Frequently Asked Questions
Why does a resolution look stretched in a game?
This usually happens when the resolution's aspect ratio doesn't match your monitor's native aspect ratio.
What's the difference between 16:9 and 16:10?
16:10 is slightly taller relative to its width than 16:9 — both are common, but most consumer TVs and monitors today use 16:9.
