This is a video I made as a response to "Sony Bravia A95K Game Dimming | Surprising Results | Real Game Testing" video by Classy Tech Calibrations: [ Ссылка ]
He found that there is no dimming over time during gameplay in HDR, but that dimming only happens in SDR. From this it follows that as long as TV is in HDR mode and receiving HDR signal, it should not dim over time in the context of gameplay with static UI elements.
This test was meant to confirm the theory that his finding means that it's possible to workaround dimming by simply keeping windows in HDR mode even when playing SDR games.
To my surprise, the test resulted in demonstrating dimming happening, and what's more, it demonstrated two different types of dimming happening.
I performed 2 tests, one with gradation preferred HDR tonemapping, the one that's most accurate, and the one that Classy Tech was using. And the second test was with HDR tonemapping off to push the brightness as far as it goes, to see what happens, for science.
Timestamps of what happens in the video:
1. Showing settings 0:00
2. Test starts 0:27
3. Dimming starts (after 54 sec) 1:21
4. Dimming ends (duration 22 sec) nothing happens for the next 6 min 1:44
5. Changing to "SDR in SDR" mode 8:12
6. "SDR in SDR" for comparison 9:00
7. Start of test with HDR tonemapping off 9:29
8. Dimming starts (after 10 sec) 9:39
9. Dimming ends (duration 123 secs) nothing happens for the next 1.6 min 11:41
10. Moving around reduces dimming, but does not remove it entirely 13:13
You might have heard that constantly keeping windows in HDR is not recommended. But this is due to most screens lacking the accuracy to properly show SDR content encoded within an HDR signal. But with A95K that's not really the case anymore due to it's accuracy.
Since both SDR and HDR on A95K are so accurate, playing SDR game in SDR or HDR looks practically the same either way when one increases HDR/SDR brightness in windows HD Color settings to achieve desired brightness.
