Ubuntu 22.04 cannot get 4k resolution working

th flag

i've got a machine with Intel 630 Integrated Graphics 630 (Kaby Lake) and a TV which can do 4K connected via HDMI (bought 2.1).

I've tried this (and also 3840x2160_30.00)

cvt 3840 2160 60
# 3840x2160 59.98 Hz (CVT 8.29M9) hsync: 134.18 kHz; pclk: 712.75 MHz

xrandr --newmode "3840x60.00"  712.75  3840 4160 4576 5312  2160 2163 >
xrandr --addmode XWAYLAND0 "3840x60.00"
xrandr --output XWAYLAND0 --mode "3840x60.00"

  Minor opcode of failed request:  21 (RRSetCrtcConfig)
  Value in failed request:  0x0

But as you can see above i get this error. Please help!

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.
