8K Resolution works only in 30 Hz - How change clock Resolution

nr flag

I have a question. I use my Computer at a Samsung 8k Television. I use Dual-Boot. In Windows 8k with 60 Hz on HDMI-2.1 is no Problem. In Ubuntu 22.04 with Nvidia 510 driver it is only possible to use 30 Hz at 8k resolution. The command "xrandr -q" shows me only 8k at 29.997 Hz Resolution. Can anybody explain me, who to add the 8k - 60 Hz resolution in Ubuntu 22.04 to the screes settings. (I use the Nvidia 5.10 .. driver , have RTX 3080 installed). Would be appreciate about an answer, Ingolf

On a similar search to have 8K from Linux I found two discussions with technical info, very different in nature from each other and in tone, with better tech info further down in discussions:

Maybe that helps you. Myself I still haven't found anyone saying they got a Linux notebook to work with an 8K TV. You are running a desktop, right?

Now I installed a new Ubuntu 22.04, once with Nvidia 510 , once with the 520 driver. And it is the same situation. It`s only possible to use 7680x4320 at 29,97 Hz. So it seems to be the Nvidia-Driver.

It is not clear that this is an answer to your original question. Perhaps this would be better as an update to your question?
I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
