Display Tests

- Stuck Pixel FixerFlashes rapidly changing colors over a stuck pixel to try to bring it back. Drag a small flashing square over the pixel, or flash the whole screen.
- Refresh Rate TestMeasures the real refresh rate of your screen, checks it against the rate it is sold at, like 144 Hz, and counts dropped frames.
