Blurred image on external BENQ monitor with NVIDIA

Post by ateshabaev » Thu Feb 08, 2018 8:20 am

Hello,

I have monitor BENQ GW2765HT. I'm connected to it with HDMI.
However, image is blurred/pixelerated as suggested resolution from the monitor is 2560x1440@60, however maximum that I see in "Display" settings is 1920x1080 (16:9).

Looking at some topics on the Internet I found something.

I did the following:

Code: Select all

cvt 2560 1440 60
# 2560x1440 59.96 Hz (CVT 3.69M9) hsync: 89.52 kHz; pclk: 312.25 MHz
Modeline "2560x1440_60.00"  312.25  2560 2752 3024 3488  1440 1443 1448 1493 -hsync +vsync
added resolution to monitor settings:

Code: Select all

xrandr --newmode "2560x1440_60.00"  312.25  2560 2752 3024 3488  1440 1443 1448 1493 -hsync +vsync
and

Code: Select all

xrandr --addmode HDMI1 "2560x1440_60.00"
Now I can see "2560x1440_60.00" in the list of "Display" resolution settings, however when I try to switch to it, system gives me back the following error pop-ups:

Code: Select all

The selected configuration for displays could not be applied
could not set the configuration for CRTC 64
and after ~15 seconds one more with the following content:

Code: Select all

Failed to apply configuration: %s
Timeout was reached
I searched through some of the similar topics on this forum and a few other websites, however they did not really help me, because I was always getting these pop-up errors after every try. Even after rebooting the system.

Does anyone know how to solve this?

Some other useful information about my system:
