TV specialists from German tech magazine “Video” put Samsung QLED TVs through a 72-hour stress test, certifying them as “burn-in free”. Conducted in conjunction with Connect Testlab, the experiment found that 2018 Samsung QLED TVs were free of burn-in and afterglow.
Testers performed measurements on the TVs to check possible burn-in effects, which can be caused by static picture elements. These effects — also referred to as “ghosting”, “image retention” or “burn-in” — are known to tangibly impair the picture quality of a television.
Engineers added variable text elements and an intermittently blinking white frame to the test picture so that the automatic stills detection customary for modern HDR TVs could not spring into action. This helped testers create similar conditions as in HDR games.
In addition to the standard analysis, testers used dark grey images with brightness values of 10cd/m², which will show if dark pixels are brightened up.
The measurements showed that the tested Samsung QLED TVs remained unaffected. Video concludes that the TV can theoretically be left on permanently without picture elements like network logos leaving an afterglow or “burning in”.
Analyst Comment
Of course, the unwritten part of this release is the implied criticism of the possible burn-in issues of OLED TVs. (BR)
