Custom Resolution

General system Newbie
1

I love playing game on a stretched resolution like 1680x1050. I just swapped from windows to Endeavouros with Gnome 42. I could configure the Resolution to 1680x1050 but i can’t set the Refresh to 240.

xrandr:

DP-4 connected primary 1680x1050+1080+1080 (normal left inverted right x axis y axis) 600mm x 340mm

1920x1080 60.00 + 239.96 143.99 119.98 59.94 50.00

1680x1050 59.95*

1440x900 59.89

I’ve tried to set a new custom resolution with the following commands:

$ cvt 1680 1050 240

# 1680x1050 239.81 Hz (CVT) hsync: 291.14 kHz; pclk: 684.75 MHz

Modeline "1680x1050_240.00" 684.75 1680 1832 2016 2352 1050 1053 1059 1214 -hsync +vsync

$ xrandr --newmode "1680x1050_240.00" 684.75 1680 1832 2016 2352 1050 1053 1059 1214 -hsync +vsync

But i am getting the following error:

X Error of failed request: BadName (named color or font does not exist)

Major opcode of failed request: 140 (RANDR)

Minor opcode of failed request: 16 (RRCreateMode)

Serial number of failed request: 47

Current serial number in output stream: 47

Tried to generate other Modelines for 1680x1050_100Hz, 1680x1050_120… etc but non did work.

Using a RTX2080ti with the following driver:

$ nvidia-smi

Does your panel support that combination?

Hello, and welcome to the forum!
Also, did you try using Wayland instead of Xorg yet?

4

Wayland and Nvidia is still not a great combination.

5

Thanks, I wasn’t aware of this.

6

it did on windows

7

Hi, i did not because heard that it isnt good with nvidia

in the mean while i could create the xrandr --newmode and it gets listed via xrandr below the usb-c:

        v: height 1050 start 1053 end 1059 total 1214           clock 239.81Hz

but when i try to add it to the output DP-4 the following happens:

$ xrandr --addmode DP-4 1680x1050_240.00 
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  18 (RRAddOutputMode)
  Serial number of failed request:  47
  Current serial number in output stream:  48

Also tried the following:

$ xrandr --output DP-4 --mode 1680x1050 --rate 240

but that just sets the Monitor to 1680x1050 with rate 60.

Any ideas how i could archive 1680x1050 with 240hz?

For everyone who runs into the problem:
If you’re trying to retain the high refresh rate at 1680x1050 resolution on a 1080p monitor, you might consider doing what I do, and use --scale-from 1680x1050 for your xrandr command.

Ie, “–output DisplayPort-0 --mode 1920x1080 --scale-from 1680x1050 -r 240”.

That high refresh rate only kicks in at higher resolutions. So make the monitor think it’s using a higher res, but scale it down to what you actually want.
