Custom Resolution Guide for 1080i HDTV-HTPC-POWERSTRIP-RADEON - Page 54

post #1591 of 1734
Has anyone successfully gotten a Pioneer RPTV (mine is a HD643 64") to work with an HTPC? I have a Radeon 9800 Pro and am using the component out. I have successfully gotten 1776x1000 to work correctly but there is some jitter with bright colors and you can notice the lower refresh rate.

I would have liked to use a 480p setting but I can't get any to work at all. That being said, for DVD and video playback it seems just fine at 1776x1000. But the windows desktop is hard to look at for long periods of time, and the resolution is so large that text is tiny and mostly unreadable when using the internet.

Is this mostly because this is a RPTV (CRT style)?

Hi Bolker,
At 50 + pages this thread is becoming unweildly for most.

I suggest that you start at the HTPC part of this forum and print out about the first 10 or so pages of this thread http://www.avsforum.com/avs-vb/showthread.php?t=206854

Karnis provides a wealth of info regarding timings and resolutions "NO MATTER WHAT TYPE OF DISPLAY" That said you still have to read his entire post before it starts to sink in.

He also advises on how not to blow the conversion and other things on your display.


Perhaps an administrator might do something to make this topic more manageable.

Thanks for the reply petermwilson.

I had actually read most of the thread and implemented Powerstrip 3, and added all of the timings listed on the first few pages. I tried them all, and only two worked at all, those being the 1080i settings of 1980x1080 and 1776x1000. The 1776x1000 worked best because the Catalyst drivers allowed me to tweak the resolution so that there was literally no overscan, and it fit my screen perfectly. Actually I was pretty pleased with the results because video and DVD work perfectly, but the flickering screen makes it difficult for anything other than playing videos and such.

After reading more it looked like everyone was in the same boat as myself if they have a CRT type display, with the exception being that others could use 480p for doing PC kinds of things and then switch to 1080i settings for videos and such. Like I said, the videos and DVD works great

Realistically, I was hoping someone else had gone through figuring out the best timings for my TV but it looks like I'm the only one here with this particular TV. My post was really in the hope that someone else knew of a timing that worked better in 1080i, or a 480p setting that I could use.

But thanks for the pointers. I continue to try out new settings and hopefully I'll be able to post my TVs optimum settings......just in time for me to buy a new DLP or TFT widescreeen.

Hi bolker,
What are you using to connect the PC to TV, & what vid card?

Please help. Sorry if this was already asked/posted.
I have a Panasonic tc32lx60 LCD HDTV, I am connected through DVI to HDMI adapter when using my PC. Using Catalyst6.9. The best I could adjust my screen was 1240X700 60hz using Catalyst, slight overscan. The TV has a resolution of 1360X768. Is there a way I can get closer to the native res? Or should I just be happy with how it is?

Hi,

I have a sharp DLP projector(specifications listed below) and I'm trying to drive it from my HTPC via DVI. Using powerstrip, I was able to run the projector at its native resolution of 1024x576. I wasn't able to get HDTV resolutions of 720p/1080i. When I tried a res. of 1280x720p, there was overscan and so I had to pan to get to the ends of the windows desktop. I couldn't even get to 1920x1080i. I have the following questions:

* How do I get 720p without overscan? I have played around with porch settings as suggested but without luck

* When I use the projector without powerstrip, it seems to assume a resolution of 1024x768. Isn't it already doing 768p in this case?

Thanks

Anyone;
What is a Windows keyboard shortcut to change resolution down to 1024x768 or 800x600 at boot or at the desktop?? I'm at some high res. and both VGA and DVI inputs won't display a image on my Microdisplay.
I really don't want to lug a 17" CRT monitor go get back the display. I can view safe mode though.

Searched hi and low, cant find an answer. I have a TH-42PX60U, and I'm trying to get the pc to display on it. I have a radeon 9800 pro, using a DVI to HDMI cable to my plasma. No matter what I do, nothing displays on the plasma. I am thinking I just am not setting the powerstrip settings correctly, anyone have any advice on what to set it to???

I have an older Pioneer RPTV (Elite 510), and these Powerstrip settings work for me for 480p:

Don't think I've tried 1776x1000, but these "work", still giving flickery text, but with manageble overscan so you can use the desktop if you get close enough to read the text:

I wish to set a 1920x1080@48Hz with nvidia drivers, XFX7950CT and Mitsubishi 5000 projector.
Somebody can help me to get it with powerstrip?
post #1601 of 1734
Hi.
I have a Vizio LCD 42" (from costco) and I can not seem to get the native resolution to work full screen. That is 1366x768. I can get 1152x648 and 1776x1000 to work just fine, I was hoping to get something in between those so the native resolution would be perfect.

I'm going component out of my HP mediacenter PC to component in on the TV.

I've tried a bunch of settings with powerstrip but I'm not sure how to achieve what I'm looking for. At least I can't figure it out on my own.

Any help would be much appreciated!

Thanks.

I have a Samsung HLP-5063W 52" DLP. I've gotten the standard timings for 720p to work on my tv from my video card (Radeon X850 PRO) over a VGA cable. I've gotten 1080i to work using some of the timings from this thread, but at this resolution, the text is blurry and flickers. Any idea how to clean up the text at this resolution? Or would this be better corrected using a DVI -> HDMI cable instead of a VGA cable?

Any suggestions would be appreciated.
post #1603 of 1734
Same as above post. I have sammy 6767; VGA input can get 1:1 pixel mapping by resizing image via TV. HDMI has no such allowed function. Picture is 10% overscanned. Nvidia allows custom timing, but my experimenting doesn't work. I notice thereisa "front-end active" and "back-end active" for both vertical and horizontal. H: FE active is 1768, BE active is 1920. V: FEA is 991, BEA is 1080. I cleverly figured if I match FEA to BEA all would be well; but it didn't work. Should I adjust back porches instead?
post #1604 of 1734
Petermwilson I am not sure if you still monitor these threads but I could use your help. I have a Toshiba 65h80 tv and I need a modeline for 1080i. I have tried to PM you and send email to the Rogers account you listed with powerstrip in the subject. I have gotten no reply.

If anyone has 1080i modeline for toshiba RPTV please send to alex.vandeusen@gmail.com or post it here.
post #1605 of 1734
Recently purchased a Hitachi 51A59 RPCRT. The only resolutions it doesn't use the less than desirable upscaler are 1080i/540P. 1080i is awfully small (plus the tv is only 1280*1080... so pixels are being dropped anyways). 540P is incredible. Far and away the best resolution! But I have real problems using powerstrip (Radeon 9800 currently using the ATI component dongle) and getting 540P to work with any consistency and to not have it crash my system.

I've used powerstrip to add the 960*540 resolution to my toolbars and it has... but it does so with letterboxs on all 4 sides and it's obviously not 960*540 since the picture is blurry and is using my sets VirtualHD scaler (Which true 960*540 doesn't).

In Powerstrip, if I choose 960*540 and go to add custom resolutions and add the 960*540 (HDTV), it remains with the borders on all sides.

If I choose ANY other resolution as my starting point, hit custom resolutions, pick 960*540 (HDTV), and hit apply... the screen switches to true 960*540 and fills the whole screen (and greys out my VirtualHD setting... meaning no scaling is involved). It's glorious. But the moment I try switching to ANY other resolution, the computer will go blank, hang, and finially hard reboot.

Anyone have any ideas at all? Thanks.

I installed Vista and connected the PC to my Sony 70" XBR2 and for some reason it'll only go up to 1280 x 1024 resolution. I'm thinking that computer doesn't know that my TV can go up to 1900 x 1080. Right now the monitor is set as Generic PnP Monitor. Is there a driver for XBR2? How do I get the to display 1900 x 1080 on the XBR2? Can Power Strip fix this? Can I use PS on Vista? Anyone have the PS download link and settings for the 70" XBR2?
post #1607 of 1734
How are you connecting it? I'm not up on the Sony labeling lingo, but I know with the LCOS based sets and VGA, the resolution is well below 1920*1080. 1280*1024 seems about what I remember VGA being.

As you seem to be guessing, the problem is the Generic PnP Monitor driver. You can actually use the latest version of PowerStrip to create a custom driver - just make one that has a refresh rate and resolution at least as high as your display supports and install that as your monitor driver. You should then be good to go.

What are the settings for an R60XBR1 SXRD running out from a laptop using an Intel 915 chipset ?
post #1610 of 1734
Hey all,

Sorry but this is a huge thread and I'm hoping someone can help me out...

I've been using the nvidia drivers on my Panasonic PT50DL54 DLP with my HTPC running a 7600GT. The image is slightly smaller then the display. I'm pretty sure the manual states a native resolution of 1280x720 - why does selecting 720p in the nvidia drivers not fill the screen? Will using Powerstrip fix this? Thanks.

Hi Karnis, can you pm me? I've read through this thread at length and you've steered other Pioneer ELite RPTV HD owners to the promised land of custom timings. I desperately need help and guidance with setting up a brand new nVidia 7950gt Vidieo card with PureVIdeo drivers to talk nicely with my Pioneer Elite 710HD display. I've burned 15 hours and have achieved zilch. Hoping you may have some custom timing ideas that I can try out!

Thanks!

I've been running component cables via the ATI Breakout cable, from my AIW9700 to my Tosh 51HX83 for the last few years.

I recently rebuilt my HTPC and finally decided to load newer ATI Drivers. To my dissappointment, when I connected the DVI cable, the same problem I had 3 years ago still exists. When the windows desktop appears, it never is centered. It's always shifted vertically. I would have hoped it be fixed by now? Anyone know why this is happening?

BTW, I have another PC that I bought a cheap ASUS NVIDIA based graphics card with DVI out. I decided to test this on my TV. To my surprise this cheap $50 card could do what my AIW could not. What gives?

So, while NVIDIA is a consideration, anyone got an AIW card driving their RPTV via DVI, without Powerstrip?

Thanks
post #1613 of 1734
I'm using a 9800XT, but yes dvi and no powerstrip. Latest ATI drivers as well.
post #1614 of 1734
umm are there any numbers for 1080p at 60 hz? Ive gone through a few pages and can't find any numbers

if it matters im running a Samsung HLS5687 and a X850XT PE card
post #1615 of 1734
Tried powerstrip on my ATI radeon.To get 1080i, seems like we have to use powerstrip to get to a 1920x1080 resolution, 30 HZ, Interlaced.

When I use the NVidia cards I don't have to use powerstip. I just connect the TV to the graphics card reboot the machine & the display settings gives me a a 1920x1080 resolution, 30 HZ, Interlaced option automatically.

I am using my old Mitsubishi 46807 & it's RGBHV DTV input. Got the VGA to RGBHV cables from a local store for $12 for 10feet long cable.

As noted earlier, the font is very small to view computer stuff and some flickering. But the DVD look good. Though I think playing the DVD thro Norcent progressive component output the picture is better than the 1080i! Wonder why that is. May be when I attache the HD DVD external drive (available from MS for XBox for $200), I will get better results.
post #1616 of 1734
Yes, 1080 will be 30 hz interlaced. I'm running a Mitsubishi 48413 at a custom resolution (1700x976 or something) using the box stock ATI stuff, and it wasn't hard to do. Most of this stuff is out of date here, the drivers do all of this now.

I didnt read the complete thread yet. I am going to connect Mits 65413 to
ATi 9800pro. The ATi driver installed does have 1920x1080 30Hz interlaced
as one of the support. Wouldnt this work without PS?
I have yet to try it out though.

I have my ATI x850PE connected via the S-Video/Component Out connector to my 32" Westinghouse W32L6. So the flickering we get when using 1080i is normal? A regular picture seems fine, but looking at a white desktop, or moving through the menu's of a program flickers lightly, is that normal?

As will become obvious from my answer, I have not been using PS for quite some time because for me, it has become obsolete so I have a different answer.

Pardon me if you already know all this as this may be old hat to some folks but not to me since I have not been in the HTPC forum for quite some time

Why not just get the cheapest Nividia based card which has DVI output?
I use the Geforce 6500 PCI-E card.


You install the unified Nvidia Driver (it handles all Nvidia GPU based cards) and the Nvidia Control Panel has settings for HDTV's.

My Geforce 6500 saw my Zenith Plasma as an 'LG PDP' and let me set it to 1280x720P (aka 720P).
The underscan was corrected by the 'Resize TV' menu .

Since the Zenith is 1366x768P Native that explains the underscan.

Once you are done dragging the left/right,up/down re-size slider to fix under/overscan, that new resolution is saved .

I have been running my Zenith this way for quite some time.
Prior to getting this Nvidia card, I did use PS with a Radeon card but,as you know it was a PITA.


I just recently completed the same thing with a 52" Sharp 1080P LCD HDTV because I replaced the Zenith with the Sharp.
The Nvidia control panel identified the display as a "SHARP HDMI"

The Nvidia control panel had a choice for 1080 Interlace or Progressive.
I picked 1080P and since that is what the Sharp is there was no need to fiddle with the over.under scan.


Hope this helps
