I started the web developement 101 and set up Xubuntu, and I have a 27" 4k display. Resolution is 3840 x 2160. I’m try to get the virtual machine to get 4k as well. It’s at 1080p right now or maybe even lower at 720p. I’m trying to look for solutions.
This forum post says to use a program called xrandr that scales the video output: https://forums.linuxmint.com/viewtopic.php?t=159064
Link to download xrandr from that post: https://cgit.freedesktop.org/xorg/app/xrandr/
But I’m not sure how if it works. Does anyone have a solution they know of?
