I'm guessing no by the lack of responses, but I'll ask anyway. Does anyone have any helpful information that they may be able to provide to assist in my many futile attempts to get my '09 Mini to display a proper resolution on my Toshiba 62MX196. I've spent so many hours over the last couple of weeks to try to get this working, I'm willing to try almost anything at this point. I've even tried going to VGA but that didn't help at all.

Thanks!!!

I can also confirm jpkad's post about the Samsung LCD set:

He was exactly right, although I was a little confused at first. I had not bothered to setup my INPUT names on the TV yet and I thought from his post that you could spell out your own INPUT names (you can so this on Sony sets I believe) ANYWAYS, it turns out there is a predefined list of names you can assign a given input and this choice affects how the set interprets the incoming signal.

I checked the manual and sure enough there is one line that references this:

"When a PC with a resolution of 1920x1080 (or 720p as I found out) is connected to the HDMI IN 1 port, you should set the HDMI/DVI mode to DVI PC in the Edit Name of the Input Mode"

Wham-o. No need to futz with displayconfigx or switchresx, it worked perfectly. no overscan. no black border.

thanks jpkad, you saved a few of my Saturday hours!

btw, the model number of my LCD is LN46B530 (it's a canadian model, eh)

Hello everybody, I have problems using my external monitor with my Macbook Pro. I have stumbled upon this post using Google.

I have a Iiyama Prolite E2403WS monitor that runs at a resolution of 1920x1200 @60 Hz. Now this reolution is not listed in the standard resolutions that Apple offers us... My Macbook runs OSX leopard 10.5.7.

So I did some research on the web and found the SwitchResX application. But I am a bit of fuzzed by how I am supposed to use it. Even when I read the tutorial at the start of this post I get lost... Can Anybody pls kindly tell me what I need to enter and where...? And than what to do.., save it somewhere and reboot?

I hope any of you can help me out..?
cheers,
Taz

hi everyone,

this seems the best place to ask questions about switchresx!

i have an old-fashioned crt tv, it's a goodmans something-or-other and it's widescreen. i'm conncecting to my intel macbook (gma 950) via the apple mini-dvi to video adapter and a coaxial cable to the composite input on the tv. someday i'll buy a nice expensive hdtv but for now i'm stuck with this!

i have managed to use switchresx to get a widescreen image rather than a stretched 4:3 image, which was my main aim, but i'd really like to get rid of the border around the image. with overscan on i lose 16 pixels from the top and bottom and 40 pixels from the left and right. without overscan, there's an irritating border around the picture.

my problem is that adjusting the porch values doesn't make any difference to the size of the picture! the resolution changes, but the physical size of the image is constant, no matter how much i adjust things. i've noticed a couple of other people on this thread had the same issue but i couldn't find a solution.

does anyone have any ideas of what to try next?

cheers,
matt

Everything was going great right up through 10.5.6 using 1024 * 768 (with overscan option checked) on my Mac mini connected to a Sharp Aquos 32" LCD via DVI -> HDMI. All that was ruined by OS 10.5.7 and I have been cursed by 1024 * 720 with huge black bars all around my monitor and fuzzy text.

I was hoping that 10.5.8 would restore everything back to normal, but have had no luck at all in that respect.

The resolution option is there, but clicking on it blacks out my TV and I am forced to screen-share into the mini to get a picture again.

Why would 1024 * 768 in 10.5.6 be different from 1024 * 768 in 10.5.8?

I have been tinkering with ScreenResX for a few hours and have come up with nothing usable yet.

Thank you for any suggestions anyone might have.

In response to my own post, just in case someone else has the same issue:

Tinkering with SwitchResX for several hours never came up with anything. I decided to give DisplayConfigX a try and literally four clicks later, it came up with a perfectly matched profile for me that filled the screen and had no blurry text. I didn't have to mess with porches or sync rates -- they were all filled in automatically.

So problem solved, but I'm still unsure why the problem ever arose -- why in the world would Apple take resolutions away, and then when they put them back in the next update, they don't work?

It was only the slightest bit off and I was able to get it perfect with just a little tweaking afterward.

When you label the input PC it enables a mode in the Picture->Size menu on the TV called Wide PC. This allows the TV to size the picture correctly.

I would also recommend that you configure Setup->Home Theater PC on, as it makes the colors look a lot better.

Hope this helps anyone else with a similar Samsung DLP.

Hi! I'm new here and had a question on your setup. I'm using similar: Mac Mini 2009 with a Samsung UN46B8000XF TV i got couple of weeks ago. Ever since i hooked up the Mini to it (and i tried both mini-dvi to HDMI and miniDP to HDMI) I've been having cropping issues where i couldn't see the menu bar at all and bottom part of the dock was also hidden from view. I saw the great SwitchResX tutorial on this forum but that didn't help (tried both older and newer versions, always got "Mode not supported" from the TV). I've updated the TV to the latest firmware too. Nothing worked. I gave up and turned "Overscan" off which was the only way i could see all of the Mac screen while using native 1920x1080@60Hz. But that doesn't fill the screen up completely.
Tonight i went into the TV menu and started playing with naming the inputs and while doing that i noticed that screen was flickering (like as if changing resolutions) when i was going through various names i can use for the inputs.
And sure enough, as soon as i scrolled to DVI PC or PC for my DVI/HDMI1 input - the screen filled up with the mac screen. How weird is this?
Whoever put this functionality into the "Name the inputs" menu - should be executed without trial...
In any event, there's still one issue I'm facing: color.
When using DVI as the name of the DVI/HDMI1 input - i get amazing rich colors but the screen is cropped. When screen is fully visible and fully filled - i get not so rich colors, they seem sort of washed out and dull. Anyone has any ideas how to fix this?
I can post pics if that helps...
I'd really like to get this to work once and for all. Never imagined i'd be having this many issues with such a simple setup.
Oh yeah, i'm on Snow Leopard...just upgraded few days ago...

Thanks in advance!

Sal.

Thanks for your post. I am new to Mac so I was wondering how I would solve this. I have a Samsung HL61a750 and my HTPC died a while back so I replaced it with a new Mac Mini (2.26Ghz Intel Core 2 Duo with the NVIDIA GeForce 9400M/256MB). I had the same problem I've read all over the place; Too much overscan (top menu bar getting cut off) or too much black space around the desktop if I used the overscan option in the Mac's display settings.

I switched the label for my HDMI3/DVI input to PC and turned the overscan option off on the Mac and just like that it was almost taking up the entire display area. You mentioned you had to do some slight modifications after that. What would those have been? I have about 1/2" of black on both sides and 1/3" on top and bottom that I'd like to get rid of if possible. It's just a relief to have it this size without the overscan problem.

Maybe I should give SwitchResX a try. I did try DisplayConfigX briefly. It seemed on my display, because it was recognized by the OS (10.6.1), that I was not able to change any of the settings.

kompuntu, do you have Color Gaumet settings on your TV? Have you tried playing with those? I am using sRGB and have my Gamma set at -3. The TV's color, tint, and sharpness are grayed out of me in this "PC" mode.

I have the new edition of the Mini (Nvidia 9400M graphics) and have my Samsung connected via min-dvi port to a minidvi-dvi apple adaptor then a dvi to HDMI cable. The TV's picture size is set to "16:9" (other options are 4:3 and wide-fit. The latter causes even more overscan).

I have the Mini set with the overscan option checked. without it, the image is way to small for the display, and SwitchResX can't increase the size enough.

The porch settings do not effect the image position at all (on reboot or on display un and re-plugging). I can get close to filling the screen, but I'm still off 55 px or so in the horizontal and 20 px or so in the vertical. compressing or extending the image size causes artifacts and blinking on the edges.

In bootcamp, I loaded up the latest NVIDIA driver set, and was able to get the overscan corrected in 2 clicks. (Boy, Apple needs to so get this working in OS X this easy). The Bootcamp 3.0 driver set didn't have a functional overscan correction, but updating to the latest and greatest from NVIDIA worked perfectly. Here's a clip of the info the NVIDIA panel shows for it's working resolution:


Entering this in SwitchResX doesn't work, the TV says "no signal" when I select the resolution in SwitchResX. Here's the SwitchResX version of the config:


I tried unchecking the positive horizontal sync in SwitchResX, and that didn't work either.

I saw the posts about later model Sammy LCD's and the Input naming, that didn't do anything for my older model.

Any ideas or suggestions?

i have the latest model macmini and was having issues with overscan like everyone else here seemed to be. I am hooked up using dvi to my TV (LG Model 47LC7DF)

I read through (Thanks everyone) for all the info in this thread. I got switchresx and tried to tweak things and kept on getting "Invalid Format" for my tv. Finally I read about changing the labelings of inputs.

If you go menu - option - Input Label and set the label of the hdmi input for the mini to PC, it immediately works. I have overscan turned on and the picture is exactly correct. No need for switchresx anymore. Hope this helps someone with a LG tv in the future.

Hello, first of all, thank you for this tutorial, it really helps a lot! I hope someone here can help me with my output on the tv.

Here is what I'm using :
Old MacBook Pro (silver keys)
DVI to component cable
Sony Bravia 40"

I've been tryting to set up my computer to output the screen on my tv, but it doesnt seem to work even though I seem kinda close I think. Here is a screenshot of my tv.



As you can see, the colors are all wrong, its all green-ish and it keeps shaking. There is a part of the tv that isnt rendering anything and my screen seems cropped.

I tried to export my DDC but Descriptor 0,1,2,3 are all empty. It seems like the computer isnt recognizing the tv.

Does anyone know which resolution I should use with my Sony Bravia 40". To get the results I have now I'm using a standard 1920X1080 60hz.

Thank you!

You can't use a cable like that, you need a transcoder ($120+) if you have any hope of going component. Plenty of threads about this in the forum. Try a search on "vga to component transcoder." Better still, try going VGA, DVI or HDMI in to your TV.

Hmm. I've been trying to no avail with my setup here.
I've got a 2009 Mac Mini running Snow Leopard 10.6.2.
I am connected to an old Mitsubishi 46809 RPTV.
I am using the Mac mini displayport to VGA dongle
I am connected to a Box1020 RGB to Component Converter via VGA cable from the Mac
The Box1020 is connected via component to RPTV.
This TV is capable of 480i,480p,1080i (Not 720p)

When the mac is in 640x480, I get correct image on the RPTV.
When I try custom 1080i settings I get scrambled screen noise.

I also have a PS3/XBOX360/DirectTV DVR all running 1080i on a component switcher to the TV no problem.

Snow Leopard has introduced the setting of "1080i" on Display preferences. This only seemes to be available when using the Minidisplayport-DVI or HDMI dongle.
VGA does not give this setting.
I borrowed an HDFury2 and ran HDMI out of the Mac, selected 1080i, then ran the HDFury2 to the Box1020 and got correct 1080i signal dispayed on the RPTV from the Mac.
Unfortunately, I don't have the HDFury2 anymore, so I would like to find the settings for DisplayConfigX to work. So far only 640x480 comes up clear.
I tried some of Fedward's methods to no avail.
I would gladly pay consulting fees to get this setup working.
This is the EDID I am seeing at present:

I have been going nuts trying to figure this all out but I feel like my Switchresx version is completely different. I have tried creating custom settings to resize my screen but nothing seems to be taking effect. Do I really have to do the
"unplug-plug back in" method? Does anyone know the proper adjustments to for it to fit? I know this is a lot of questions with little info but it was up all night trying to figure this out and i may be losing it. thanks for any help you can provide.

Someone please help!!!!

I'm using an Intel based Macbook Pro hooked up to a Samsung ln-s2651d using a mini display port to HDMI connector. With this, I get 720p, and 1080i settings. They look ok, but they're either too small for the TV (black border all around) or too big with overscan on (can't see sides or top and bottom too well).

I thought I could fix the issue with SwitchResX, and I did get SOMEWHERE with it. I was able to get what seemed to be the right screen size and what have you, but the image was pushed too far to the left (I got this blue flickering bar on the right side). So, I figured I could just move the image right using the front and back porch settings. But, IT DOESN'T WORK.

My question is why. I have tried everything and it just won't work. Am I missing something? Or should I try DisplayConfigX? I don't really want to spend $20 before I know it works, but this whole process is driving me crazy!!!
Thanks to anyone in advance who can help me or give me any info. I really appreciate it!

Hi all,

This thread has allowed me to figure out how to use SRX, so I thought I'd post my results, in case it helps somebody else...

First, the info off SRX:

-----------------------------------------------------
------------------- MAIN EDID BLOCK -----------------
-----------------------------------------------------

EDID Version........1.3
Manufacturer........MEI
Product Code........19360 (4BA0) (A04B)
Serial Number.......0000022C

Manufactured........Week 51 of year 2006
Gamma...............2.20

Monitor Description blocks:
---------------------------
Descriptor #0 - Timing definition:
Mode = 1280 x 720 @ 50.000Hz
Pixel Clock............. 74.25 MHz Non-Interlaced

Horizontal Vertical
Active.................. 1280 pixels 720 lines
Front Porch............. 440 pixels 5 lines
Sync Width.............. 40 pixels 5 lines
Back Porch.............. 220 pixels 20 lines
Blanking................ 700 pixels 30 lines
Total................... 1980 pixels 750 lines
Scan Rate............... 37.500 kHz 50.000 Hz

Image Size.............. 1434 mm 806 mm
Border.................. 0 pixels 0 lines

Sync: Digital separate with
* Positive vertical polarity
* Positive horizontal polarity


And here's what I use (after gradual trial and error):

Pixel Clock: 74.18

Active: 1216 / 684
Front Porch: 478 / 21
Sync Width: 40 / 5
Back Porch: 252 / 36
Blanking: 770 / 62
Total: 1986 / 746
Scan Rate: 37.351 / 50.069

Positive Sync: Yes / Yes

Note: The values in bold are the only ones I modified - the other ones changed automatically.
Also, I have 'Overscan' enabled on the mac.

... Alex ...

I tried to configure switchresx for a few hours, and could not get it right at all. I then read a post over at apple.com and it recommended I go into the TV settings and mess around with it. 1 minute later I had the mac mini showing perfect on my monitor. Here is my settings as well as the post.

wide mode = full

Auto Wide = ON

4:3 default = off

Display Area = Normal

I have my mac display settings at 1080p, but SRX says it's 720p or 1080i. It won't let me adjust 1080p settings. maybe this is because the signal is going through an older denon av receiver on its way to my newer panny hdtv, but whatever. the mac doesn't get confused when it shows me supported display resolutions, so i'm not sure why SRX is.

The tutorial worked for 720p...BUT...it seems to introduce glitchy video performance. moving a window with the mouse causes the display to flash...like it can't keep up. my mac mini is a brand new intel dual core, so i'm not sure what's going on there.

oh, regarding the tutorial, YMMV, but using the arrows is a lot easier than doing the math. it does the auto-compensation math for you.

edit: i think most of my woes are due to the fact that my mac mini goes through a denon A/V receiver. i've been in conversation with the program author (who has been very helpful), and as soon as i get a long enough hdmi cable, i am going to connect the mac directly to the plasma.

Hi, I thought I'd tell my story as it may help others here as this post helped me. I'm very inexperienced with all aspects of fixing this problem... I'm also relatively new to OSX. So I'm sorry if I'm stating the obvious.

My gear:
early 2009 mac mini 2.26 320 gb
Toshiba 32" lcd (32HL86) 720p/1080i with 1 hdmi input
the mini -> mini-DVI to DVI -> DVI to HDMI cable -> HDMI on the TV

On 1080i the screen is too small, overscan is too large. Don't have any fancy "just scan" or similar feature on the TV.

First off here is the EDID for my TV

Monitor Description blocks:
---------------------------
Descriptor #0 - Timing definition:
Mode = 1920 x 540 @ 60.053Hz
Pixel Clock............. 74.25 MHz Interlaced

Horizontal Vertical
Active.................. 1920 pixels 540 lines
Front Porch............. 88 pixels 2 lines
Sync Width.............. 44 pixels 5 lines
Back Porch.............. 148 pixels 15 lines
Blanking................ 280 pixels 22 lines
Total................... 2200 pixels 562 lines
Scan Rate............... 33.750 kHz 60.053 Hz

Image Size.............. 708 mm 398 mm
Border.................. 0 pixels 0 lines

Sync: Digital separate with
* Positive vertical polarity
* Positive horizontal polarity

Descriptor #1 - Timing definition:
Mode = 720 x 480 @ 59.940Hz
Pixel Clock............. 27.00 MHz Non-Interlaced

Horizontal Vertical
Active.................. 720 pixels 480 lines
Front Porch............. 16 pixels 9 lines
Sync Width.............. 62 pixels 6 lines
Back Porch.............. 60 pixels 30 lines
Blanking................ 138 pixels 45 lines
Total................... 858 pixels 525 lines
Scan Rate............... 31.469 kHz 59.940 Hz

Image Size.............. 708 mm 398 mm
Border.................. 0 pixels 0 lines

Sync: Digital separate with
* Negative vertical polarity
* Negative horizontal polarity

So I got SRX and attempted to follow the guide by fedward, as well as the BSteely's Generalized Timing Formula (GTF) solution. Neither worked... I ended up with many black screens which required just as many safe mode start-ups or my custom resolution's status of "not activated - invalid?" (but this may have worked in the end even though the status indicted it didn't... please see step 7 and 8 below)

As I have two macs i set up the mini to be controlled through a remote desktop via Chicken of the VNC. Here's a guide to setting it up (of course the computers need to be networked)...
http://www.dssw.co.uk/blog/2007/05/1...-mac-os-x-104/
(step 3 in SL, I turned on Remote Mangement. When you click Remote management a box pops up... check all boxes, hit OK, then go to Computer Settings, check "VNC viewers may control screen with password" and enter a password)

This is how I made the rest work.
1) system Prefs -> displays -> 1080i, then to Options -> Overscan (for some reason I could not increase the size of the "underscaned" screen, but could decrease the size of the overscaned screen)
2) System prefs -> SRX -> Launch Daemon
3) Select Toshiba-TV on left menu bar -> Custom Resolution
4) Plus-sign for new custom res. The options were all prefilled to my current resolution, which matched my EDID completely (1920 x 1080).
5) I then used the Quick Change buttons to shrink the vertical and horizontal resolutions. After many, many changes and restarts (no, unplugging and replugging the hdmi cable did not install the resolutions) I ended up with a resolution of 1024 x 1032 that fit my screen well.
6) After changing the resolution with the quick change buttons you need to save by selecting File (in the menu bar at the top of the screen) -> save settings. Then the status of the custom resolution changed from "not installed" to "restart required." I restarted the mini.
7) here's where i wasted a lot of time. I would then go back into SRX and Custom Resolutions to find the status as "Not activated - invalid?." At this point I'd start all over trying to make everything work (as mentioned above fedward's guide didn't work...well it may have in the end)
8) Go to the current resolutions tab (right next to custom resolutions) and there I found my newly created resolutions... (e.g. 1824 x 1032, 60Hz (NTSC)). Select that resolution and it worked.

Sorry if this was painfully simple... as I said it took me hours to figure this out, when it might have been right the whole time. Good luck!

Now I just need to fix the colour because it's way too rich on the TV.

Well I have an older mac mini and I just swapped cables to try something. DVI to VGA cable from the mac to my Sony 60" SXRD display. In system preferences the best resolution available is 1360 x 768. It let me do 1080 last time!

Goodness now what? hehe

BTW, I've got a long-standing problem getting the mac mini to fill the screen of my TV.

im having trouble understanding something, and just looking for some help. I have a macbook with a MDP > HDMI adaptor connected to my Sharp LC-37PD5X. I can't believe i actually bought this piece of crap with no VGA input, but thats beside the point. I have been able to get it working through a 1080i preset (below)

Code:
Pixel Clock - 74.25    -  Overscanned & Interlaced
                  H                         V
Active:     1920px                1080L
FR Por        88px                    4L
Sync W       44px                  10L
Back Por    148px                  30L
Scan         33.75kHz              60Hz
The problem with this setting is I cannot see the menu on the bottom of the screen, the width of the Horizontal is nearly all the way to the borders of the TV, so i tried to shrink the visible on the Vertical with this set

Code:
Pixel Clock - 74.25    -  Overscanned & Interlaced
                  H                         V
Active:     1920px                1000L
FR Por        88px                    47L
Sync W       44px                  10L
Back Por    148px                  68L
Scan         33.75kHz             60Hz
This worked sweet on the vertical side but it brought the horizontals in about 2 inch's on each side of the tv frame, and it seems any changes i make to the horizontal active (keeping it balanced of course) makes no changes to the screen at all, i am able to move the screen around with the front and back porch just not able to make active area any larger. Any ideas please ??

The instructions for this are great. However, I can't get all of the values to stay at the same total.

I want to increase the size on the left side and the right side to fit the image to screen.

So I increased the active vertical pixels by 16 and decreased the horizontal porches by 8 pixels each. I didn't touch the synch width and I ensure the scan rates and pixel rates were the same as they were in the EDID file that I exported. The problem, is that the blanking cells changed (and they cannot be altered in switchresx). The result is that the total visible + blanking do not equal to what they were in the original EDID settings - and from the original tutorial here, it seems like that is essential.

Is anyone else coming accross this problem and if so what is the fix? Do the values not need to add up to the EDID values?

I've also been having some trouble getting SwitchResX to play nicely with my Sharp LC-47SB57UT LCD HDTV. I've used SRX as well as other frequency tweaking software out there for the mac and nothing seems to help. Ive played around with every single setting on my TV but its always the same in the end. I've tried everything with overscan on, and with overscan off. I've tried creating whole new settings and then restarting to a black screen - only to have to unplug-and-re-plug again. I have since gotten wise and now use a VNC service from my iPhone to get back in and change the resolution when I have a black monitor

I even dedicated a part of my blog in hopes someone will come across it and send some help my way!
(link below, I had to break it up b/c I dont have sufficent privlidges to post a URL yet to this forum)

http:// sketchstudios.net/ wordpress/2010/04/switchresx-call-for-help/

I am going to yet again, spend another night tinkering with the settings and hope I get lucky. Until I find out the exact solution I'm in the same boat as many of you - but like many of you - I too will not cease until the problem is solved. Once that happens, Ill be back here to post the results.

I ended up just setting the display settings to 720p and then stretching the picture. It fits the 60" screen perfectly now, albeit in 720p... but with a macbook (mini dvi-dvi-hdmi) it was never going to be 1080P anyways. It looks pretty good. Obviously I would love to get it as close to 1080P as possible, but i'm happy for now until someone tells me how to solve my problem. Have you tried this yet?

Hi all,

I've recently re-used an old Intel Mac Mini (with the DVI connector at the back) to connect to my TV, so I've purchased a DVI+Audio to HDMI converter (I think it's the same model sold by MonoPrice, CAT-6066).

First, the info off SRX:

-----------------------------------------------------
------------------- MAIN EDID BLOCK -----------------
-----------------------------------------------------

EDID Version........1.3
Manufacturer........CAT
Product Code........24678 (6066) (6660)
Serial Number.......00000000

Manufactured........Week 50 of year 2006
Max H Size..........60 cm
Max V Size..........34 cm
Gamma...............2.20

Detailed Timing Block #5 - Timing definition:
Mode = 1280 x 720 @ 50.000Hz
Pixel Clock............. 74.25 MHz Non-Interlaced

Horizontal Vertical
Active.................. 1280 pixels 720 lines
Front Porch............. 440 pixels 5 lines
Sync Width.............. 40 pixels 5 lines
Back Porch.............. 220 pixels 20 lines
Blanking................ 700 pixels 30 lines
Total................... 1980 pixels 750 lines
Scan Rate............... 37.500 kHz 50.000 Hz

Image Size.............. 603 mm 342 mm
Border.................. 0 pixels 0 lines

Sync: Digital separate with
* Positive vertical polarity
* Positive horizontal polarity


And here's what I use (after gradual trial and error):

Pixel Clock............. 74.25 MHz Non-Interlaced

Horizontal Vertical
Active.................. 1208 pixels 680 lines
Front Porch............. 476 pixels 25 lines
Sync Width.............. 40 pixels 5 lines
Back Porch.............. 256 pixels 40 lines
Blanking................ xxx pixels xx lines
Total................... 1980 pixels 750 lines
Scan Rate............... 37.500 kHz 50.000 Hz

Image Size.............. 603 mm 342 mm
Border.................. 0 pixels 0 lines

Sync: Digital separate with
* Positive vertical polarity
* Positive horizontal polarity

Note: The values in bold are the only ones I modified - the other ones changed automatically.
Also, I have 'Overscan' enabled on the mac.

Hello there,

I am searching for a tool that can fix the following problem.
I have been searching for an answer everywhere but I can't seem to find it. Maybe it's because I have a special setup.
I have been using SwitchResX for a couple of days now but I can't find to get what I want.

At the moment I am using a MacBook Pro and its connected via DP/DVI/USB -> HDMI cable (from Apple) to my television.
This is the new Philips 21:9 (resolution 2560x1080). When I start the MacBook the WHOLE screen is white with the startup logo from Apple in the middle. (no borders left of right)

I set my MacBook to a resolution of 1920x1080 (or 1080p) but whatever I do I cant get the full screen filled. Left and right are borders. Overscan doesn't help too, still some borders left and right and I miss a lot on the top and bottom of the screen.

I also have serveral other HDMI stuff connected, like XBOX360, PS3 and a Popcorn media box. All expand to full screen?

Is there something I miss?

I am planning to buy the new Mac Mini (with HDMI on board). I read that it supports higher resolutions so that would be nice. But still this has to work.

Thanks in advance.

I recently purchased a 2010 Mac Mini, which is so far pretty fantastic, and it pretty much fixes the overscan issue (I'm using a Panasonic th-42pz80u for a display), at least for me. However, one frustration is using the Mac interface at a distance. From the discussions I've seen of SwitchResX, you can associate resolutions with different programs, but I haven't been able to find any discussion of what resolutions people suggest for, say, web browsing and the like. Any suggestions? Or is this something better performed with AppleScript?

Also, how does switching between applications on the fly (Mac button + tab, if memory serves) work? If I, say, go from Safari to Plex, how quickly does it switch (or does it switch at all)?

Suggestions?
