01 / Instructions
How to use this test
Choose the gradient or contrast pattern. Enter full screen. Look in normal lighting without changing several settings at once.

Understand your result
Abrupt steps or invisible patches can reveal an issue worth comparing at another brightness or in another browser.
03 / Testing methodology
What this test cannot tell you
This is a visual check, not colour calibration or an HDR certification. Ambient light and browser rendering change what you see.
