Doctor OLED TV is a toolbox for OLED TV owners.
OLED TVs should be handled with care to avoid image retention and screen burn-in, because the OLEDs degrade over time. Also typically, some of the big OLED panels have vertical banding issues which can be visualised with this App.
It includes the following test;
1. Burn-in 1
2. Burn-in 2
3. Equal brightness
4. Checkerboard test for image retention
5. Vertical banding 1
6. Vertical banding 2
7. Play non burn-in colors
This app can only display graphical content on your TV, it does not claim to cure your TV for any sorts of issues or artefacts. If you have detected issues during these tests, consult your TV reseller for help and advise.
Enjoy, your rating, feedback is much appreciated.
