Nate Graham <n...@kde.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|REPORTED |NEEDSINFO Resolution|--- |WAITINGFORINFO CC| |n...@kde.org --- Comment #1 from Nate Graham <n...@kde.org> --- 4k@120hz requires: - A GPU that supports HDMI 2.1 - A monitor that supports HDMI 2.1 - Either an HDMI cable that supports HDMI 2.1, or an HDMI cable that supports HDMI 2.0 and then you have to turn off HDR, 10+ bit color, and use 4:2:2 chroma 4k@60hz requires: - A GPU that supports HDMI 2.0 - A monitor that supports HDMI 2.0 - An HDMI cable that supports HDMI 2.0 In both cases, if even one requirement is not fulfilled, you won't get what the monitor is capable of. So please verify that all the necessary hardware devices support the required HDMI version and your settings aren't overdriving what the cable is capable of. -- You are receiving this mail because: You are watching all bug changes.
