Using KDE Neon, a Vega 64, and a Pixio px277h, I have tried to manually make xrandr use the setting for 144hz because it does not seem to detect this properly. The monitor has 144hz capability, the cable that comes with it also probably does (it is labeled high speed), and the Vega 64 has HDMI 2.0, so there should be no problem on the hardware side. Here is some more information:

The option with information from cvt and input with addmode are there, but why can't I use it? How can I fix this? I know that a Vega graphics card has the capability to do 2560x1440 and 144hz based on this video:

The option with information from cvt and input with addmode are there, but why can't I use it? How can I fix this? I know that a Vega graphics card has the capability to do 2560x1440 and 144hz based on this video:

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
Also have a look atXorg.0.log, the EDID, and the result of the modeline checks. Even if your monitor supports 144 Hz, your graphics card may have a limit on the pixel clock rate, and may be unable to do 144 Hz at 2560x1440 (though it may do 144 Hz at lower resolutions).

More specifically, you seem to be using--addmodeincorrectly (without a prior--newmode), hence the link to the "duplicate" question, which gives a more detailed example usage.

Here is a video of someone reviewing the monitor. He is using a Vega graphics card and achieving 144hz. youtube.com/watch?v=cB5RRdTi9bY

Using KDE Neon, a Vega 64, and a Pixio px277h, I have tried to manually make xrandr use the setting for 144hz because it does not seem to detect this properly. The monitor has 144hz capability, the cable that comes with it also probably does (it is labeled high speed), and the Vega 64 has HDMI 2.0, so there should be no problem on the hardware side. Here is some more information:

The option with information from cvt and input with addmode are there, but why can't I use it? How can I fix this? I know that a Vega graphics card has the capability to do 2560x1440 and 144hz based on this video:

Using KDE Neon, a Vega 64, and a Pixio px277h, I have tried to manually make xrandr use the setting for 144hz because it does not seem to detect this properly. The monitor has 144hz capability, the cable that comes with it also probably does (it is labeled high speed), and the Vega 64 has HDMI 2.0, so there should be no problem on the hardware side. Here is some more information:

The option with information from cvt and input with addmode are there, but why can't I use it? How can I fix this? I know that a Vega graphics card has the capability to do 2560x1440 and 144hz based on this video:

Also have a look atXorg.0.log, the EDID, and the result of the modeline checks. Even if your monitor supports 144 Hz, your graphics card may have a limit on the pixel clock rate, and may be unable to do 144 Hz at 2560x1440 (though it may do 144 Hz at lower resolutions).

More specifically, you seem to be using--addmodeincorrectly (without a prior--newmode), hence the link to the "duplicate" question, which gives a more detailed example usage.

You've forgotten the first xrandr command:
xrandr --newmode 2560x1440_144.00 "808.75 2560 2792 3072 3584 1440 1443 1448 1568 -hsync +vsync"
And a wrong last line:
xrandr --output HDMI-A-0 --mode 2560x1440_144.00

I did use --newmode first, but hadn't put it in the commands. The option for --newmode where the quotes are not around the name, but the parameters seems to not work. xrandr --newmode 2560x1440_144.00 "808.75 2560 2792 3072 3584 1440 1443 1448 1568 -hsync +vsync" xrandr: failed to parse '2560x1440_144.00' as a mode specification Try 'xrandr --help' for more information.

I did use --newmode first, but hadn't put it in the commands. The option for --newmode where the quotes are not around the name, but the parameters seems to not work. xrandr --newmode 2560x1440_144.00 "808.75 2560 2792 3072 3584 1440 1443 1448 1568 -hsync +vsync" xrandr: failed to parse '2560x1440_144.00' as a mode specification Try 'xrandr --help' for more information.

You've forgotten the first xrandr command:
xrandr --newmode 2560x1440_144.00 "808.75 2560 2792 3072 3584 1440 1443 1448 1568 -hsync +vsync"
And a wrong last line:
xrandr --output HDMI-A-0 --mode 2560x1440_144.00

Also have a look at
Xorg.0.log, the EDID, and the result of the modeline checks. Even if your monitor supports 144 Hz, your graphics card may have a limit on the pixel clock rate, and may be unable to do 144 Hz at 2560x1440 (though it may do 144 Hz at lower resolutions).– dirkt

More specifically, you seem to be using
--addmodeincorrectly (without a prior--newmode), hence the link to the "duplicate" question, which gives a more detailed example usage.– n.st

Here is a video of someone reviewing the monitor. He is using a Vega graphics card and achieving 144hz. youtube.com/watch?v=cB5RRdTi9bY
