Frequently asked questions
Does this test fix burn-in?
No. It only helps reveal possible retention or uneven wear.
Which displays can burn in?
OLED, plasma, and other emissive technologies can develop persistent uneven wear. LCD image persistence has different causes.
How long should I run the test?
A few seconds per pattern is normally enough for inspection. Avoid long static display times.
