Hallo,
ich versuche jetzt schon längere Zeit erfolglos 4k mit 60 Hz unter Ubuntu zum Laufen zu bekommen. Ich nutze ein Asus Notebook mit einer Intel UHD und ein HDMI-Kabel. Der Hinweis, den ich mit Abstand am häufigsten gefunden habe, ist, dass es wahrscheinlich am Kabel liegt. Da es mit dem Kabel aber unter Windows klappt, scheint es mir in meinem Fall nicht die Ursache zu sein.
Ich wäre für jeden Tipp sehr dankbar
