NVIDIA Dual Monitor not working

I have two monitors, 1 QNIX 1440p running at 100hz that is properly working, the other, and 1080p Asus at 60hz is running at 1024x768.

Here is my xorg.conf

Re: NVIDIA Dual Monitor not working

You haven't provided any information alluding as to what is specifically happening with your configuration; What exactly is wrong with your second monitor?

I mentioned at the top that the 1080p Asus (60 hz) is running at 1024 x 768.
I have been using nvidia-settings and 1024 x 768 is the highest resolution available for that monitor.
Are there any more config files I should post or anything?

Re: NVIDIA Dual Monitor not working

Hi,

I have the same issue. I've made a fresh install of Arch the other day and my second screen in not properly detected. The first monitor works perfectly but 800x600 is the highest resolution I can get in nvidia-settings for my other monitor. Everything used to work perfectly before reinstallation.  And I'm sure there is no hardware problem.


Regards

Re: NVIDIA Dual Monitor not working

I haven't had to deal with xorg.conf files since I started using arandr from the standard repo - it's a simple X Window interface to xrandr and allows you to enable/disable monitors, set resolutions, and place the screens in relation to each other.  A really useful tool.

Re: NVIDIA Dual Monitor not working

I was hoping today's nvidia + xorg upgrade would solve my problem... it didn't. Thanks Joe for arandr, I didn't know that tool. However I don't seem to be able to add other resolutions. Still stuck with 800x600 on my second monitor.

Haven't tested this yet, I'll let you know.


Really disappointed that the last update did not solve anything.

Re: NVIDIA Dual Monitor not working

it is not a bug in driver, it is actually a communication problem between your monitor and the driver. You will be able to add resolutions very easily.

Re: NVIDIA Dual Monitor not working

Alright. Thanks a lot. Do you have some kind of explanation of why it used to work perfectly and it doesn't anymore ?
