Linux 无法检测到 Vega 64 的 2560x1440 144z 功能

Linux 无法检测到 Vega 64 的 2560x1440 144z 功能

使用 KDE Neon、Vega 64 和 Pixio px277h,我尝试手动使 xrandr 使用 144hz 的设置,因为它似乎无法正确检测到这一点。显示器具有 144hz 功能,附带的电缆也可能具有(标记为高速),并且 Vega 64 具有 HDMI 2.0,因此硬件方面应该没有问题。以下是更多信息:

来自 cvt 的信息和带有 addmode 的输入的选项都在那里,但为什么我不能使用它?我怎样才能解决这个问题?根据此视频,我知道 Vega 显卡能够支持 2560x1440 和 144hz: https://www.youtube.com/watch?v=cB5RRdTi9bY

答案1

您忘记了第一个 xrandr 命令:

 xrandr --newmode 2560x1440_144.00  "808.75  2560 2792 3072 3584  1440 1443 1448 1568 -hsync +vsync"

最后一行错误:

xrandr --output HDMI-A-0 --mode 2560x1440_144.00
