How to use
- Let the monitor warm up for 15 minutes and set the room lighting as you normally use it.
- Turn off dynamic contrast, eco modes and image "enhancements" in the monitor menu.
- Open each pattern in full screen (click to go to the next one) and follow the hint above it.
- Adjust brightness with the black pattern, contrast with the white pattern, then check gamma and gradients.
Frequently asked questions
Is this a real calibration?
It is a visual adjustment. A colorimeter is needed for exact color and gamma measurements, but these patterns fix the most common problems: crushed blacks, clipped whites and wrong sharpness.
Why do I not see the darkest squares?
Brightness (black level) is too low, the panel cannot show them, or the graphics driver uses a limited 16–235 range. Raise the brightness until steps 2–3 are just visible.
I see stripes in the gradients.
Some banding is normal on 6-bit and many 8-bit panels. Strong banding often comes from color profiles, "vivid" picture modes or low contrast settings.
