The resolution is usually limited by build-in graphics card in display ,however, we can obtain a higher resolution by modifing it via software built in linux forced.
Such as my low-end laptop,We can get any resolution rather than 1024x768 the maximum resolution setted in laptop default.
The reference:
For example: enter below command in your terminal#!/usr/bin/bash
# panning constrain the mouse cursor boundaries
xrandr --output LVDS1 --fb 1229x922 --scale 1.2x1.2 --panning 1229x922
# scale parameter should be calculated by yourself like: 1229/1024 = 922/768 = 1.2
# you can increase the lighting contrast of font if it's pale (range from 0 ~ 1.0)
xgamma -gamma .7
