Increase monitor DPI with xrandr

# MoreDPI - increase resolution beyond monitor limits
alias moredpi="xrandr --output VGA1 --scale 1.25x1.25 --panning 1280x960"
In this case, the upper resolution limit of the monitor [VGA1] is 1024x768 (4:3). The screen is scaled down by 25% [--scale 1.25x1.25]. A "--panning" argument is given to allow this new area be interacted with.

To return the screen to default settings, the following alias is used:
# LessDPI - reset resolution to default
alias lessdpi="xrandr --output VGA1 --mode 1024x768 --scale 1x1 --panning 1024x768"
