Although we have not tested the Burn-in effect of subtitles on OLEDs, we expect that subtitles can cause burn-in. Attached are a few pictures of an LG C7 that one of our visitors has kindly shared with us. These pictures were taken after 7100 hours of TV usage during which content with subtitles was displayed. Green, Magenta, Red, Orange,Yellow, Blue, Cyan, RealContent.
UPDATE Here are the pictures from the same TV after 11500 hours of use. Green, Green-2, Red, Blue-1, Blue-2, Pink, RealContent. We wish to thank our visitor for his contribution.
Update: Weโve updated the CPI graph displayed in the Sensor Latency section of this review. Our results remain the same, but these graphs have two new columns with results from the Delay At Half Movement and Delay To End Of Movement tests.
