Default Re: Which NVIDIA Graphics Cards can display 2048x2048 ?

Hi!

Thanks guys. I would have never set up a BARCO ISIS on NVidia card if I wouldn't have found this posts.

I am using Gigabyte GeForce 8500 GT graphics card. XWindows work on BARCO but I am not able to setup a second screen on analog output of the same card. I think it should be possible. there is also one funny thing. The menu on BARCO gets strangely interlaced when I am running it on NVidia. It can not be seen very well on the picture but one can get an idea.

My xorg.conf looks like this now:
# Xorg configuration created by system-config-display

I was trying to configure secondary screen and I had some problems. Finally I made it. Here is xorg.conf for two displays:
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 1.0 (buildmeister@builder75) Tue Dec 8 21:07:34 PST 2009
