VRR flicker tested, is there an OLED that doesn't have it? Do IPS and VA have it? Does vesa Adaptive Sync prevent it?

The to all the questions is No

Rtings now test for VRR flicker and are the only ones doing so. They've done 25 monitors at first

Link below to the full testing results, but the summary is that:

* All OLEDs have VRR flicker, but all are not the same, some monitors are much worse than others.

* IPS and VA also have VRR flicker, but it is almost unnoticeable in IPS in general, while VA is in between and depending on the monitor, VA can flicker as bad as OLED

* Gsync/Adaptive Sync/Freesync does not prevent flicker

For the test, Rtings runs content, such as a game and has the system frequently changing the framerate from equalling the monitors max refresh, to 10hz under the max and switching between the two - for example a 120hz monitor would be tested by rapidly changing from 120fps to 110fps and flicker is defined by changes in the screens output brightness during this change in framerate
