There are a couple of known issues with EDID interlaced modes that we hope to fix in a future driver release.

Can you give us a way to work around it? For now I can't use ANY 1080i modes under linux.... I've tried every "option" listed in the forums, and can't get the driver to believe the EDID information.

The data right from the log:

Quote:

(--) NVIDIA(0): VSyncEnd, VTotal : 547, 562
(--) NVIDIA(0): H/V Polarity : +/+
(--) NVIDIA(0): Extra : Interlaced

The bugger is.... how does THAT turn into THIS?

Somehow, the driver needs to believe the EDID. I just can't come up with a way to make that happen.

You may be able to work around the problem by using nvidia-settings to save the EDID to a file, editing the mode in question to double the vertical timings, and then feeding it back to the driver with the CustomEdid option. I haven't tried that particular approach so I don't know if it'll work. Other than that, I don't think there's a workaround for this problem.

I've searched the forums, but does anyone have a good step-by to do this?

Default Re: 1080i EDID modes broken in 100.14.19

It's working. I got 1080i modes working again. What a PITB...

I spent approximately 20+ hours over the last couple days, and was able to get it working.

XRANDR is still broken, any mode switches BACK to a 1080i mode end up with the double-size/half-screen issue, but as long as I don't switch modes, it's working.

What finally worked? Explicit mode line:

Quote:
ModeLine "sony1920" 74.2 1920 2008 2052 2200 1080 1088 1091 1121 +hsync +vsync interlace
For reference, here are the xorg.conf options:
Quote:
Section "Device"
Identifier "Videocard0"
Driver "nvidia"
BoardName "NVIDIA GeForce FX (generic)"
Option "RenderAccel" "1"
Option "NvAGP" "3"
Option "XvmcUsesTextures" "true"
Option "ConnectedMonitor" "DFP-0"
Option "ModeValidation" "NoVertRefreshCheck,AllowNon60HzDFPModes"
Option "IgnoreDisplayDevices" "CRT"
Option "AllowGLXWithComposite" "true"
Option "AddARGBGLXVisuals" "True"
Option "UseEDIDdpi" "false"
Option "UseEvents" "True"
EndSection

I'm working on resolving the XRANDR issue.. I think I'm going to ignore all EDID completely and carve out a couple of lines.

Oh, here's my monitor section. This is specific to the Sony 60" XBR1.

Quote:
Identifier "Monitor0"
VendorName "Sony XBR 60 SXRD"
ModelName "XBR 60 inch SXRD"
HorizSync 15.0 - 46.0
VertRefresh 59.0 - 61.0
ModeLine "sony1920" 74.2 1920 2008 2052 2200 1080 1088 1091 1121 +hsync +vsync interlace
Option "DPI" "100 x 100"
EndSection

FWIW, Given the volume of CORRECT data that comes back from the TV via EDID, I think it's a monster screwup to have it broken so badly under linux. Under windows, it's perfectly fine.... So I have hope...

The xrandr issue that you cite may be the key to reproducing this for nVidia.

Many of us here are using this with MythTV, and we have X starting in a different mode (720p or something like that) and then only use 1080i when playing back 1080i material. What you're saying is that you can get 1080i working, but only if it's the starting resolution.

BTW: I've used that exact same modeline previously with no luck--just a black screen (not the messed up screen that I get with EDID values).

Have you tried all the same xorg.conf options as well?

Default Re: 1080i EDID modes broken in 100.14.19

Since I upgraded from a Geforce 7 to a Gerforce 8 (driver 100.14.19) my modeline for a sanyo plv-z2 beamer doesnt work properly anymore, the mode gets validated with edid ignored and some other validation skips but the resulting output is much too small and the beamer cant recognize it as 720p anymore.
(the same xorg.conf works great with the geforce 7 and the older driver)

Dunno if that fits into this thread or if my problem goes even further (as i have edid disabled)

I just wanted to chime in and say that I also have this issue. 1080i mode makes the desktop 1080 lines high, but displays only the top 540 lines. The TV is a Philips 42PFL7432D.

I should specify that the computer is connected via HDMI (it is a 7050-based motherboard). And the mode in question is one of the EDID modes sent by the TV. Custom modelines with doubled vertical timings do not work for me. The TV fails to sync to these modes.
