screen resolution issue

Hey arch,
My problem is that I am unable to increase my screen resolution. The max is 800x600. My card:

[david@arch64-home ~]$ lspci | grep VGA
00:0d.0 VGA compatible controller: nVidia Corporation C61 [GeForce 7025 / nForce 630a] (rev a2)

I have installed nvidia prop drivers as per instructions in the wiki.
My monitor is a Sony LCD 32". It supports upto 1360x768 resolution. I tried setting it via "nvidia-settings " but the screen goes out of bounds.

Please help....

<jawdrop> 32"?! Is it a TV?

Please post the output of `grep -E '^\((W|E)' /var/log/Xorg.0.log'.

In your xorg.conf I see a CRT, not an LCD, I don't know if that means anything.
I see you're using TwinView - does that mean you have another monitor attached? If so, is it working correctly?

Re: screen resolution issue

Hey Karol,
Thanks for your reply.
Yes its a TV. I already had one and dont have enough cash to buy a monitor for the pc. So I am using the TV. Will post the Xorg.0.log as I get home this evening. I have added CRT as that was what the nVidia asked me to do as I am using a VGA cable. I specified twinview just as a trial and error thing. I have just one monitor.

I know nothing about hooking up a TV to a PC, but I think you may need to manually (and not via nvidia-settings and the like) specify the resolution and refresh rates.

What DE / WM do you use? What's the output of 'xrandr'?

Re: screen resolution issue

sudo xrandr 
Screen 0: minimum 1360 x 768, current 1360 x 768, maximum 1360 x 768
default connected 1360x768+0+0 0mm x 0mm
   1360x768       50.0*

I have configured these settings according to my TVs manual.

xrandr says you have 1360 x 768 @ 50, if your manual says it's fine, they should work.

Do you get 1360 x 768 or some other res? Did you try values other than 50 for refresh? How about 60?
