Default Can't fill 1080i Sony KDS-R50XBR1 screen

Using the latest 173.14.09 driver on Mythbuntu 8.04, the default screen resolution is only 1216x684, and the maximum is 1600x1024.

Neither of these fills a 50-inch Sony rear projection 1080i HD screen. Instead there's a 320-pixel black border on the left and right, and a 152-pixel black border top and bottom (these border dimensions are just the difference between the 1920x1080 native screen resolution and what this card and driver are actually showing).

Thanks in advance for clues on getting this card and driver to use the entire screen.

bump.

Still haven't figured out how to get a full screen display on Sony KDS-R50XBR1 DLP TV.

Thanks in advance for any clues.

Thanks. I have attached a gzipped copy of nvidia-bug-report.log.

I'd previously searched the archives for clues about configuring for this particular TV but didn't find specific instructions.

Again thanks in advance for tips on configuring X to fill the entire screen.

You are not using the nvidia driver.
Your xorg.conf specifies the VESA driver.

and you have a stupid 'Modes' set there.

edit your xorg.conf! add nvidia and remove modes - with edid they are not necessary (should not be necessary).

OK, this system now points to the nvidia driver but I'm still banging my head on the wall over two problems:

1. The image fills the entire screen when using the DVI-to-HDMI connection but the image quality is very poor -- green, grainy and contrasty with vertical red bars.

2. The picture looks MUCH better over VGA but the image size maxes out at around 1280x800 or so, leaving a big black border all around.

Naturally I'd prefer to use DVI-to-HDMI but at this point I'm stuck. Thanks in advance for any pointers on filling the entire display and getting decent video quality using either set of connectors.

still looking for help on getting this to work with a DVI-to-HDMI connection. If I wanted 1024x768 VGA, I wouldn't need this nice Nvidia card...

Again, I get either very poor image quality (or, currently, no image) when using the DVI-to-HDMI connection.

Thanks in advance for any clues in troubleshooting this.

you just get what you asked for:
Section "Screen"
Identifier "Default Screen"
Device "Configured Video Device"
Monitor "Configured Monitor"
SubSection "Display"
Modes "1024x768" "800x600"
EndSubSection
EndSection

make that
Section "Screen"
Identifier "Default Screen"
Device "Configured Video Device"
Monitor "Configured Monitor"
DefaultDepth 24
SubSection "Display"
Depth 24
EndSubSection
EndSection

Default Re: Can't fill 1080i Sony KDS-R50XBR1 screen

Thanks for getting back to me. Unfortunately removing the modes doesn't clear the issue. Neither does removing the "Depth 24" statement (which nvidia-xconfig does).

I've attached the bug log from the boot sequence with "Depth 24" included.

Either way, the failure is the same:

1. Very grainy ASUS BIOS splash screen

2. Terminal screen with vertical red stripes across screen

3. Blank screen once X starts

This Nvidia GEForce 7200 card has both DVI and VGA output, and both are cabled to the TV. The VGA output appears OK, but only at 1024x768 max with black borders all around.

Thanks again for further clues in getting the display to work with HDMI/DVI and at full screen.

Default Re: Can't fill 1080i Sony KDS-R50XBR1 screen

I think the problem lies here:

(II) NVIDIA(0): Validated modes:
(II) NVIDIA(0): "nvidia-auto-select"
(II) NVIDIA(0): Virtual screen size determined to be 1024 x 768

at that point it should choose the highest supported resolution. Hmmm

maybe you really need to play with this option:
Option "UseEDID" "boolean"

and give the right freqs and resolutions. Sorry.

No apology necessary; I appreciate your help.

I don't know how to determine frequencies and resolutions with this particular TV (Sony KDS-R50XBR1). It's been something like 15+ years since I last messed with X; I remember a tool called modeline but it isn't included with mythbuntu. Is there some other way to find this info?

thanks again
