1440p and 1080p monitor not working together.

Graphics / Linux Linux
1

I’m running driver version 337.25 on an Archlinux 64 bit system. This problem occurs both on the CK kernel and standard kernel. I can run the 1440p monitor or 1080p monitor alone, when I attempt to run both, only the 1440p monitor works. The 1080p is attempting to run at 2048x1536. When I attempt to run it at a lower resolution, which is scaled, it still fails to run. Here is my /etc/X11/xorg.conf

I’ve tried a variety of settings, but none have worked.

Hi KingofKingsss,

Is there any particular reason you’re not using the monitor’s EDID? You can debug mode validation problems by enabling the “ModeDebug” option, starting X, and the examining the X log to determine which modes were rejected, and why.

I didn’t use the EDID because I don’t know how to find it.

[ 17.165] (II) NVIDIA(GPU-0): Validating Mode “1920x1080”:
[ 17.165] (II) NVIDIA(GPU-0): 1920 x 1080 @ 60 Hz
[ 17.165] (II) NVIDIA(GPU-0): Mode Source: X Configuration file ModeLine
[ 17.165] (II) NVIDIA(GPU-0): Pixel Clock : 172.80 MHz
[ 17.165] (II) NVIDIA(GPU-0): HRes, HSyncStart : 1920, 2040
[ 17.165] (II) NVIDIA(GPU-0): HSyncEnd, HTotal : 2248, 2576
[ 17.165] (II) NVIDIA(GPU-0): VRes, VSyncStart : 1080, 1081
[ 17.165] (II) NVIDIA(GPU-0): VSyncEnd, VTotal : 1084, 1118
[ 17.165] (II) NVIDIA(GPU-0): H/V Polarity : -/+
[ 17.165] (WW) NVIDIA(GPU-0): Mode is rejected: HorizSync (67.1 kHz) out$

is why the proper mode is rejected, I’m not sure how to fix that. It then goes to Nvidia Autoselect, which attempts to put it at 2048x1536. The 1080p option nvidia settings gives me is at 85hz. The 1080p monitor is 60hz, the 1440p is overclockable.

[Edit]

I set the EDID sections for the 1080p monitor to true. It now defaults to 1280x1024 and still too high a frequency. I’ll keep working on it.

[Edit]

It now works at 1024x768. I’ll work with it more tomorrow and post a working config if possible.

[Edit]

1080p!
