I have a Dell Precision 5510 with a 3840x2160 screen, connected to a monitor with a 1920x1200px resolution. In order to use them together I followed what is suggested here. In other words, executing:
xrandr --output eDP1 --auto --output HDMI1 --auto --panning 3840x2400+3840+0 --scale 2x2 --right-of eDP1
However, I get several problems:
- The worse is my graphics card slows down a lot.
- Also, it sometimes freezes and restarts with no warning. This can be really dangerous if it continues to happen.
Does anyone have an idea of what I could do, or what could be wrong?
