XBMC(liveusb) + projector = resolution problem

[morphy.g]

hi

i have a LiveXBMC (thread-link (http://xbmc.org/forum/showthread.php?t=32853)) with a GF6600 and an Acer DLP Projector.

if i change the resolution on a tft (1024x768) and than switch the cable to the projector, the picture is perfect!

i restart the XBMC and the XBMC changes the resolutio to
640x480 or to 1600 x XXX....

is it possible to change the resolution in a conf-file and switch off the monitor/resolution-detection?

xorg.conf:

Section "Monitor"
Identifier "Monitor0"
VendorName "Unknown"
ModelName "Unknown"
HorizSync 31.0 - 80.0
VertRefresh 50.0 - 85.0
Option "DPMS"
EndSection

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1024x768"
EndSubSection
EndSection

Yes i had a similar problem.

I own a dlp projector which is naitive 720p but will also accept upto a 1080p/24 signal.

Linux thinks (or my projector tells linux?) that it only supports upto 720p and this is the best option it gave me.

To fix it, i used the nvidia settings manager to force a 1080p picture and i suspect you could do the same.

I think the nvidia settings manager will just alter the contents of xorg.conf but is an easier way to do it for a non-techie.

i cant start this manager, because i have not gnome/kde

can you post your xorg.conf?

is there a possibility to switch off the automatic resolution detection?
...and force the XBMC to use only one given resolution

i solved the problem.

with this xorg.conf (with modifications for my projector):
