Default LCD-TV max 640x480 resolution

I have a 7600gs card and one LCD(1600x1200) connected with DVI.

Today I bought a LCD-TV(720p) and connected it with a standard VGA cable. But nvidia-settings only give me the option of 640x480 or 320x240 and calls my LCD-TV a CRT?

How can I fix this?

If you're connecting to the TV with a VGA cable, then its treated as an analog TV. I'd guess that the TV isn't providing an EDID, so the driver is falling back to a 640x480 mode.

If you'd like further assistance, please see the forum sticky posts.

Sorry, didn't read the sticy posts.

Is it posible to generate the EDID-file my-selves, I see there is a option for providing one in nvidia-settings.

Attached the nvidia-bug-report.log file.

Tried to connect the TV to my laptop running X.Org 7.3 and using the latest intel driver the one named intel(not i810). Xrandr detected all supported resolutions for my TV, so should be posible.

As I suspected, the EDID isn't getting read:
(WW) NVIDIA(GPU-0): Unable to read EDID for display device CRT-1

However, a large part of your problem is overly conservative HorizSync in xorg.conf :
(WW) NVIDIA(0): Mode is rejected: HorizSync (37.9 kHz) out of range
(WW) NVIDIA(0): (28.000-33.000 kHz).


As for the intel X driver, its possible that its alot less cautious about default modes, or it doesn't use the defined HorizSync in xorg.conf.

I can't see any refrece to HorizSync in xorg.conf, should I just add it and if so where and to what value?

Because your CRT monitor has no EDID, you need to specify the sync ranges yourself with the HorizSync and VertRefresh options. You should be able to find the appropriate values for these in the owner's manual for your monitor.
