I recently installed kubuntu 23.04 on this laptop which supports 120hz on my laptop screen but in display configuration it says it only supports 60hz. I tried wayland and x11.

This is the output of sudo get-edid | parse-edid:

Looks like i2c was successful. Have a good day.

EDIT 1: Whenever I boot through recovery mode on X11 it says that 91hz is the only supported refresh rate. When I restart and boot normally I can only select 60 hz.

Try setting your scale to 100% and see if it allows you to go to 120Hz.

@Terrance I tried 100% and it doesn't work.

If you are using XOrg there might be a way of using the Horizsync and Vertrefresh https://askubuntu.com/a/789553/231142 Unfortunately, I am not going to be much more help beyond this since I don't have any 120Hz monitors to test with. +1 to help with visibility and we can hope someone has an answer for you.

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.
