1 Attachment(s)
Hallo,

my problem is that my Amoi HDTV-LD (until 1080p on HDMI) have only max resolution 1280 x 720 on the Geforce FX 5600 DVI ouput.

My Dist. : Kubuntu 6.10 Edgy Eft
act. nvidia packet vers. 1.0.8774

Geforce FX 5600:
APP 8x
Integrated RAMDAC
128MB
Bois vers. 4.31.20.28.00
max. pixelclock 165 Mhz
VGA + DVI + TV S-Video Connectors

Amoi LCD-TV :
HDMI connector , resolution : 1080p(HDMI), 1080i (YUV), .....

How should I configurate correctly my xorg.conf that I can use full 1080p on the LCD HDMI connected on Geforce with DVI connector ?

Enclosed my Xorg.0.log file .

Best regards Friedhelm

This problem is frequently posted on this board and you did not obey the guidelines for posting a problem report, so do not be surprised that nobody reacts anymore.

By now it is wellknown that many screens, especially TV sets with PC-input, provide incorrect EDID data. This is caused by the limitations of the EDID system as well.
Unfortunately NVIDIA obeys the EDID data as if it were the only truth, and discards your directions to use the correct resolution (1920x1080).

See the driver README and other threads on this board for ways how to work around this.

Thanks for response, but in a forest of infos and spec. for an newcommer on ubuntu dist. ist's not easy find the info's are helpfull (when actual for the specf. dist. and not for an older one etc... )

Can you give some search "keys" to find the workaround (if exit !) and for the actual README nvida ?


I found this : http://www.nvnews.net/vbulletin/show...highlight=HDTV

but ther is no solution / workaround ...
I think ist's still a construction and not fixed issue...

No what's this :

First try things like:
Option "ModeValidation" "NoDFPNativeResolutionCheck"

when that is not enough, try:
Option "UseEDID" "FALSE"

Of course you need to provide a correct modeline in that case.

I'll tried :
Option "ModeValidation" "NoDFPNativeResolutionCheck"
and also at the end
Option "UseEDID" "FALSE"

Don't helps rearly...

Then I've done this

1) Start X with level 6 verbosity:
# X -logverbose 6
2) Killall X
3) Look Xorg.0.log file: see enclosed file

It seems the driver have poor support for these monitors....
