1440p 144hz monitor stuck at 60hz

nc flag

I have a 1440p 144hz monitor connected to my system via HDMI. My CPU is an intel i5 10400 in an ROG Strix z490i motherboard. I don't have a dedicated graphics card so I am just running off of integrated graphics. My motherboard supports HDMI 2.0 and I am pretty sure that I am using an HDMI 2.0 capable cable. I am on Ubuntu 22.04.1 with Kernel 6.2.9 installed.

In my display settings, the refresh rate is listed as 59.95hz and I have no option to change this. Before on a 1080p 144hz monitor it only let me go up to 120hz max. I have tried running xrandr --rate 144 and I get the output Rate 144.00 Hz not available for this size. I get the same output trying xrandr --rate 60.

As far as I understand, hHDMI 2.0 support 1440p to at least 120hz and support 1080p at 240hz, so I am not sure why I don't have the option to increase my refresh rate. Intel UHD graphics 630 should support this refresh rate as well. I am new to linux so I'm not sure if there is something that I'm missing. Please help me fix this.

You are using an untested kernel. So the driver in that kernel may be a problem. What version of Ubuntu are you using?

I am using Ubuntu 22.04. I was having the same issue on the fresh install of Ubuntu, I tried updating kernel to see if that resolved the issue.

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.
