I've set my 272URDF monitor to 1080p at 320Hz in both Windows settings and the Nvidia Control Panel. However, when I run tests on TestUFO, it only registers at 144Hz. I'm using an HDMI 2.1 cable. Is this a problem with the cable or could it be a software issue?

Did you check your monitor settings? Also, which GPU are you using?
Actually, it should handle 320Hz just fine. 4K at 144Hz is well under the HDMI 2.1 bandwidth, so 1080p at 320Hz shouldn't be a problem. Here's a detailed breakdown you might find useful: https://www.rtings.com/monitor/learn/hdmi-vs-displayport
Double-check if you have RivaTuner or any similar software installed. I had a similar issue where I was stuck at 120 FPS after upgrading to a 240Hz monitor because of it. That could potentially limit your FPS.
Yeah, HDMI 2.1 can definitely do what you're asking for. I trust the bandwidth is sufficient enough to support 480Hz with 10-bit color as well.
It might just be a miscue with TestUFO. You could try playing a game that supports high FPS—like, see if you can tell the difference when you cap it at 144 FPS compared to breaking past that to 360 FPS. The difference should be noticeable if everything's working right.
