andersschroder, can you explain what you mean by setting up a text doc? I am not familar with that feature in SRX. Otherwise I would like to help.

Thank you! If you read the first post, fedward sets up switchresx by exporting DDC. It outputs the settings that switchresx detects as a text file as far as i understand. Then he changes the text file and loads the info back in. And bam, he has some new modes to select. If there is an easier way to do it, it would be great =)

My lcd screen runs 1366*768 but switchresx detects 1280x720. It leaves the picture with big fat borders around the edge of the screen and if i select overscan it crops too much of the picture.

btw i'm going dvi->hdmi

Hope you can help.

Yes, there is an easier way to input a video timing into SwitchRes X by using its built-in calculator that is based on something called the Generalized Timing Formula (GTF). By using the GTF calculator, all you need enter is the format, namely 1366 by 768 in this case, and the desired vertical refresh, usually 50Hz or 60Hz, and SRX will calculate and fill in all the other boxes based on the GTF. The way to do this is as follows:

Open SRX and click on the Custom tab. Click on the "+" symbol to add a new timing. A new window will open with the current video timing values inserted. At the bottom of that window, put a check mark in the box for "Use simplified settings:" and then in the associated pop-up select "GTF". Now go into the timing cells on the window and you should see that you can only enter values for Horizontal Active (set this to 1366) and Vertical Active (set to 768) and then set the correct Vertical Scan rate, which I guess will be 50Hz for that particular Sony, though 60 might also do, so you may need to try both. Then click the OK button and follow the directions for saving and restarting. The newly created timing should then show up within the normal OS X Displays preferences pane.

I have to warn you, I read the English language version of the user manual for your Sony TV and did not find a single mention of how to connect the TV to a PC. That's usually a bad sign. This TV seems to only be compatible with conventional video timings like 1080i, 720p, 480i, etc. but it may not necessarily work from a timing equal to the panel's native resolution. So I can't promise a good outcome from using SRX as I have outlined above. I wish you luck.

Thank you so much. I tried your trick but everytime my lcd goes black and states that it doesnt work with that resolution. Bummer I guess i wont get this screen to work. But thanx anyway for helping me out =)

Hello all, I'm a new member here but have lurked for a while now. Thanks for the good SwitchResX tutorial posted above.

For what it's worth I have my Mac mini 1.66 Core Duo connected via DVI --> HDMI to a Panasonic Viera TH-50PX80U and am using these settings:

Horizontal (H) active - 1224
H front porch - 136
H Sync - 80
H Back porch - 208
Vertical (V) active - 688
V front porch - 22
V sync - 5
V back porch - 36

I originally found these settings for a TH-42PX60B, and adjusted the vertical front and back porch in order to move the image down a bit. At this point I am missing just the top of the Apple leaf in the menu bar, and I have the full Dock. (I'll update this post with a link once I'm allowed )

I still need to experiment in order to eliminate the periodic horizontal shift. This thread was a nice help in adjusting the porch settings.

Thanks all!
post #70 of 131
I used your settings for my 50px80u and I got the same results. Thanks!

Have you updated your settings for better results?

Have you tried to create a custom setting for a 1080 signal from the mac?

Thanks again!

What is the 'Export DDC' Descriptor info based on exactly? Is it factory default info retrieved from the monitor/HDTV or can it be changed by dabbling with the resolutions. The reason I ask is that my 1080p HDTV shows descriptor info exactly as my current resolution of choice (1360x768) but I don't think this non-native resolution would be retrieved from SRX as a factory default, though I'm fairly certain that when I began using this app (before I found this thread) that it wasn't 1920x1080p either because this Sharp doesn't support 1080p over VGA/RGB (though it can be achieved with PowerStrip in XP)... I think originally it came out as 1440 or some oddball resolution, eventually I had the best luck in OSX by going with 1360x768 (same res I use in Windows with ease) but this left black bars on the left and right (horizontal front and back porch) in OS X, unlike XP which displays perfectly (or as perfectly as can be for scaling to non native res.. I've been trying to eliminate these black bars for awhile now and then I came across this thread.

Anyway, I attempted to reset the DDC info back to factory default, and rebooted... with the mindset that it wouldn't make sense to work off DDC info which doesn't fill my screen and which I created. Now, I have blank screen on reboot on both HDTV and Macbook Color LCD. I'm operating in the dark and have no alternative but time machine restore or fresh install. Any ideas?
post #72 of 131
ok, fresh format, and my suspicion was correct. If the Exported EDID information (i.e. the resolution therein) doesn't look so good (which presumably is the reason one is using SRX in the 1st place), how can proper settings be derived using these numbers as a basis?
post #73 of 131
I give up trying to get 1:1 Pixel mapping (or as near as I can) over analog miniDP to VGA to my Sharp HDTV with the aluminum Macbook. I have literally spent hours upon hours on this. 'Counter intuitive' is an understatement. Unfortunately Sharp (in their infinite wisdom) does not have proper EDID info on the D64U series. I guess it made more sense to their R&D to have a non native default resolution for VGA input. SWX reports 1360x768, but max according o Sharp over VGA has always been 1600x1200, which is idiotic considering a. it's a WS panel and b. native res is 1080p. However, in Windows environment, I can go with default Powerstrip EIA TIA timings for 1080p and get perfect 1:1 pixel mapping in VGA with my desktop. Not so with Mac and/or SRX in Leopard (I haven't tried in bootcamp wtih Powerstrip). What happens with identical timings (i.e. porches, sync width) is the picture is shifted off far right into the horizontal front porch abyss, and while the vertical timings can be tweaked to get a perfect up and down (which gave me so much hope, and consequently wasted hours of my day testing), no amount of tweaking with horizontal porches and sync width yields a perfect picture with bot no bars on the sides AND no vertical (what can only be described as) pin stripes. I can only get one or the other and both require different active horizontal pixels and different totals. Which brings me to my dilemma... In my scenario you actually must change the horizontal totals (the lower you go from from 2200, the wider it gets) for if you don't, porch adjustments via the quick tool or manually will not do a single thing.

Much easier dealing with my 37" Sceptre in the bedroom which reports accurate EDID 1080p info, but this Sharp is quite another story.

If only the new MB had a HDMI output, I think it would be quite another story for me, and a lot less headaches.

You need to get a MiniDP to DVI adaptor and then a DVI to HDMI cable. You will then have HDMI out, as you wish.

I have been playing wiht switchresx for a while to try to fix my picture size when piped through the Harman Kardon avr 355 to my toshiba regza 42".
I can't get anything to change at all! doesnt seem to matter what i do. is this the AVR?
two quick questions:
1. do i need to have overscan active in os x?
2. does "reboot" mean quite switchresx and restart, or reboot the computer?

Yes, it probably is the AVR. Try connecting directly to your TV.

negative... i don't have the audio input to support the HDMI TV input I'd be using. Unfortunately, Apple patronizes their loyal users by utilizing esoteric, obscure formats with inferior specifications as the miniDP supposedly doesn't have a pin out for audio. Of course, there's no miniDP to HDMI... don't even get me started on that but sufficed to say, I'm not a proponent of the double adapter solution.

I really wish I could have got this going... I literally spent hours tinkering with SWX; even employed my wife's assistance... and tried it the 'correct' way. No go so I ended up spending way too much time attempting to delineate differences in pixel clock, scan rate, sync width, porches, res, pixel/scan totals, etc. I either get full screen with a lower res and which requires a lower total, but is hampered with translucent pin stripes, or I can get higher resolution, abiding by the 'total' rule, but with bars on both sides... porches adjustments don't do squat.
post #78 of 131
I'm surprised you are having so much trouble with a D64U series Sharp. That series has a pretty good track record and reputation with the Mac plug-and-play crowd. For most people, it just works. The only thing many people have missed is the Sharp's dot by dot setting, but once they figure that out, they're done. No SRX required.

I can't seem to get my Mac Mini to display properly on my Samsung HLT5087S. I have it hooked up with a DVI->HDMI connector.

With overscan on and 1920x1080 resolution I am losing the menu bar and some other real estate on the screen. If I turn overscan off, the picture won't even fill up the screen at 1920x1080.

I've been mucking around with SwitchResX to no avail. I've gotten the settings from the EDID and plugged them into a custom resolution for the Samsung. Same results as before, so I started adjusting the resolution and porch values as described earlier in this thread.

The resolution seems to make a difference, but if I only change the porch values it doesn't seem to shift the picture at all. Has anyone had any luck with getting a mac mini setup on a Samsung DLP like this?

I will mostly be using Plex, which I can calibrate to compensate for the overscan. However, I would really like to get the desktop fitting the screen adequately if possible.

Any suggestions would be appreciated.
post #80 of 131
I figured it out by accident. In the TV setup if you go to Sources->Edit Names and select "PC" as the name of the source for the Mac Mini the TV then figures out how to size the screen properly.

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.

Hey jpkad - I just found this thread yesterday, been wrestling with getting my HLT5087S to display the output from my Mac Mini correctly. Can you tell me what firmware you're running on that set? Even after assigning the correct name ("PC") to the input (which is HDMI-DVI) i get no such display option (WIDE PC) and cannot find the Setup-> Home Theater PC toggle you speak of. I'm either missing it here or perhaps these features have been enabled in a more recent firmware release? Is this working for you with Overscan on or off? (i.e. - does the WIDE PC setting upscale or downscale?)

I'm generally having the same issue with non-overscan giving me too much border, and overscan mode cropping off my menu bar, etc etc. I've also had a hard time getting SwitchResX to play nice, some of the porch settings seem to yield results, others don't do squat, so its been tough using process of elimination, i never get a black screen, but most of the time the changes dont seem to do anything at all. The documentation for that app is just terribly vague and non-intuitive. If anyone has the true resolution / porch settings for these sets, it would be a huge help for me, using DisplayConfigX's test screens i managed to ballpark the true 1920x1080p rez to somewhere around 1890x1032 with overscan ON (reducing the size of the display to fit inside the frame), but any changes i make seem to occasionally move the display around slightly, but never seems to shrink the overall size.

Hi,
After spending few hours and corresponding with Stephane Madrau, I decided to last try to check with you guys if you can solve my resolution problem.

I was sitting for more than 5 hours trying to configure my Toshiba Regza 42" (1366X768 is the native resolution, to be precise) and could not find a solution - I am keep getting black screen when switching to the custom resolution.
I read both the help, manual, tutorial and forum.

I was hoping to get you advise before giving up.

I am attaching the Exported File (Toshiba-TV).

The custom setting I used was for (I am attaching a screenshot in the word file):
Horizontal - Active : 1360
Vertical - Active : 768
Interlaced - was checked
Positive Sync (both for Horizontal and Vertical) - were checked I used Simplified Settings - GTF (also tried CVT)

Thanks in advanced!

Gadi.

I've registered just to say thank you for this hint

It worked perfectly with Mac Mini (2009) connected to Samsung LN-T4661F via Monoprice Mini Display Port to HDMI Adapter.

Thanks again!

Hello,

I recently used the SwitchResX app to fill out a 1920x1080 space with a Boxlight digital projector.

At least, I think I did.

I followed the steps from the tutorial explicitly as I was having the same problem with the truncated 1920x540 resolution.

When I completed all the steps, there was no change, I was still seeing a 1920x540 image on the projector. However, when I went into the Apply Display options in System Preferences, I noticed that a bunch of new options had opened up.

Does that mean my custom resolution preset actually allowed for more options in the Apple Display menu? For some reason, I thought the changes I made in SwitchResX would be applied automatically.

I guess I'm just wondering if my tinkering with SwitchResX did anything or if some other unknown variable changed the options in Display options.

Hey BSteely, big fan of your Sharp related support on Apple Forums... think I've even replied in a couple of your threads.

Aquos doesn't like VGA off the Mac, what can I say... output is matted on WS resolution... even after tweaking endlessly with SRX, it's either the bars, other weird anomalies. I just gave up with marginal settings, and will be content with it until Apple releases a MDP to HDMI adapter with audio. Hopefully they do...

In fairness, Aquos never had their act together with the D64Us as EDID info doesn't report true max res over VGA... what kept me going is that I know with my U series, 1920x1080p 1:1 can be achieved over VGA on PC; not so on the S series (later revision D64U); not so with either [S/U] revision on late '08 model Macs.
post #86 of 131
I solved through SwitchResX i have a Panasonic TH50PZ80E, but i think (hope!!!) my settings should be correct for all Panasonic 50″.
Here my parameters for 1080p:
Horizontal Vertical
Active 1832 1026
Fr Porch 568 29
Sync W 44 5
Bk Porch 196 65

I hope they will be useful.
P.S. In my Mac Mini a reboot was not sufficient to apply settings. I had to power cycle the mini, or if i only reboot it was necessary enter a "power saving" cycle when OS X loaded, i mean enter and exit pressing power button shortly.

Have a nice tuning!

damn i have a 46" sammy as well and I couldnt get this to work for me and my 2009 mini
post #88 of 131
I wish I understood why this is so terribly difficult to get working. After trying with no luck to get a proper resolution with my '09 Mini on a Toshiba 62MX196, I got the settings from someone who got it to work with a very similar Toshiba 62MX195. This resulted in a black screen for me. I've tried many other settings based on information found in this thread or other places on the web, and they are either not applied, or result in a black screen. The native resolution of this TV is 1920x1080@60Hz. That is what the Mini is outputting and it results in black borders on four sides with overscan off and missing edges with overscan on. I've probably spent a good 20 hours on this over the last few days. Any ideas to get this working before I go back to vga?

Thanks!!!
post #89 of 131
Well, I got it working great on a TH-C50CD18 (the costco model of the p80U) with the exception of a bright blue line running down the right side of the screen. I'm thinking I need to make the image about 6 pixels wider and move it over to the right, should this work? I'm going to try when I get home, but it's frustrating that everything else is perfect except for that
post #90 of 131
I have a Panasonic TC-P50X1 hooked up to an Intel Mac Mini. After several hours and countless attempts, I'm stumped. Similar to many here, the image is either too small with overscan off or cropped with overscan on. Custom SRX settings that make me optimistic only give me a black screen.

I'm open to any and all suggestions.

Thanks
