at a higher resolution than your monitor supports (sort of). The
folks at LinusTechTips explain how.  This "trick" is really the
usage of a lesser-known type of anti-aliasing, called Ordered
Grid Super Sampling Anti-Aliasing. Unlike regular anti-aliasing,
which just smoothes out the edges of your game's graphics,
OGSSAA basically sends a higher-than-native resolution signal to
your monitor, and then downsamples it to your monitor's native
resolution for a sharper image all around. LinusTechTips forum
user tabuburn explains it well:  [For example,] Your display is
natively able to support a resolution up to 1920x1080. Using
Downsampling it will send out a signal to tell your display to
output a resolution of 2560x1440. Now on a display that can
output a maximum resolution of 1080p has about 2 million pixels
while a 1440p displ
