[Ubuntu-x-swat] [Bug 1990170] Re: HDMI refresh rate at 4k 144hz cant be set

Thanks for the bug report. This appears to be either a hardware problem or a bug in the Nvidia driver. I think most likely it's due to insufficient HDMI cable bandwidth. Please ensure you are using an HDMI 2.1 certified cable capable of at least 40 Gbit/s. An HDMI 2.0 cable will not be good

[Ubuntu-x-swat] [Bug 1978153] Re: Video plays back as grayscale and compressed on left

Yes comment #16 shows the bug is in intel-media-va-driver. But if you install intel-media-va-driver-non-free instead then that should be free of the bug. ** Tags added: kinetic ** Changed in: intel-media-driver (Ubuntu) Importance: Undecided => High ** Changed in: intel-media-driver (Ubuntu)
