Hi, I recently got myself a UHD monitor. https://www.amazon.com/dp/B07JXCR263?tag=aboutcom02lifewire-20&linkCode=ogi&th=1&psc=1&ascsubtag=4138562%7Cneef17e57867342f0bc4b3af20a9ba60801 However, when I connect to my 3840x2160 resolution laptop and use xrandr (through HDMI, supplied with the monitor) I do not even get an option for 3840x2160. Here is what I get: $ xrandr Screen 0: minimum 320 x 200, current 3840 x 2160, maximum 16384 x 16384 eDP-1 connected primary 3840x2160+0+0 (normal left inverted right x axis y axis) 294mm x 165mm 3840x2160 60.00*+ 59.98 59.97 48.00 3200x1800 59.96 59.94 2880x1620 59.96 59.97 2560x1600 59.99 59.97 2560x1440 59.99 59.99 59.96 59.95 2048x1536 60.00 1920x1440 60.00 1856x1392 60.01 1792x1344 60.01 2048x1152 59.99 59.98 59.90 59.91 1920x1200 59.88 59.95 1920x1080 60.01 59.97 59.96 59.93 1600x1200 60.00 1680x1050 59.95 59.88 1400x1050 59.98 1600x900 59.99 59.94 59.95 59.82 1280x1024 60.02 1400x900 59.96 59.88 1280x960 60.00 1440x810 60.00 59.97 1368x768 59.88 59.85 1280x800 59.99 59.97 59.81 59.91 1280x720 60.00 59.99 59.86 59.74 1024x768 60.04 60.00 960x720 60.00 928x696 60.05 896x672 60.01 1024x576 59.95 59.96 59.90 59.82 960x600 59.93 60.00 960x540 59.96 59.99 59.63 59.82 800x600 60.00 60.32 56.25 840x525 60.01 59.88 864x486 59.92 59.57 700x525 59.98 800x450 59.95 59.82 640x512 60.02 700x450 59.96 59.88 640x480 60.00 59.94 720x405 59.51 58.99 684x384 59.88 59.85 640x400 59.88 59.98 640x360 59.86 59.83 59.84 59.32 512x384 60.00 512x288 60.00 59.92 480x270 59.63 59.82 400x300 60.32 56.34 432x243 59.92 59.57 320x240 60.05 360x202 59.51 59.13 320x180 59.84 59.32 DP-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 597mm x 336mm 1920x1080 60.00* 50.00 59.94 1680x1050 59.88 1280x1024 75.02 60.02 1440x900 59.90 1280x960 60.00 1280x720 60.00 50.00 59.94 1024x768 75.03 70.07 60.00 832x624 74.55 800x600 72.19 75.00 60.32 56.25 720x576 50.00 720x480 60.00 59.94 640x480 75.00 72.81 66.67 60.00 59.94 720x400 70.08 Why is this so, and what do I do to get the UHD resolution? I would really like to match my laptop resolution (in fact, this was why I bought this monitor). The box says 4K UHD 3840x2160 resolution. Any suggestions?
