I am using a stack monitor setup on my laptop, one is using hdmi to hdmi and one is using usb c 3.0 to hdmi

[Schluca]

My top display keeps shuddering with the usb c when I do anything I've tried everything to fix it. I tried a ufo test and my bottom display works fine no lagging issues and tried it on the usb c and it says performance warning and looks like its shuddering every 2 seconds PLS HELP ME

Details are helpful. It’s possible the cable you’re using is adapting to HDMI and the port doesn’t support HDMI Alt mode. DisplayPort from the Type C port might be better here. What cable/adapter? What refresh rate is the top display set to?

in bios is the hdmi alt mode I saw that should I enable, the display is 1080 144hz and the cable is some china cable off amazon its rated for thunder bolt 3/4 and 4k 144hz highest and 1080p 240hz

should I try enabling usb c dp alt mode in bios?
