KDE Neon、Vega 64、およびPixio px277hを使用してxrandrが144hz設定を使用するように手動で試しましたが、これが正しく検出されないようです。モニターには144hz機能があり、付属のケーブルにも144hz機能があり(High-Speedと表示)、Vega 64にはHDMI 2.0があるため、ハードウェアの面では問題ありません。詳細は次のとおりです。

cvtの情報とaddmode入力オプションがありますが、なぜ使用できないのですか?この問題をどのように解決できますか?このビデオに基づいて、Vegaグラフィックカードが2560x1440と144hzをサポートできることがわかりました。 https://www.youtube.com/watch?v=cB5RRdTi9bY
答え1
最初のxrandrコマンドを忘れました:
xrandr --newmode 2560x1440_144.00 "808.75 2560 2792 3072 3584 1440 1443 1448 1568 -hsync +vsync"
最後の行が間違っています。
xrandr --output HDMI-A-0 --mode 2560x1440_144.00
