# First we need to get the modeline string for xrandr | |
# Luckily, the tool "gtf" will help you calculate it. | |
# All you have to do is to pass the resolution & the- | |
# refresh-rate as the command parameters: | |
gtf 1920 1080 60 | |
# In this case, the horizontal resolution is 1920px the | |
# vertical resolution is 1080px & refresh-rate is 60Hz. | |
# IMPORTANT: BE SURE THE MONITOR SUPPORTS THE RESOLUTION |
