black pluge very hard to discern on oled display #6

is this pluge pattern designed for oled use? playing the pattern on LG oled at default factory settings most of the pattern is black and indiscernible.

The pattern is correct. It's designed for use with every type of display, and yes OLED. The whole point of this pattern (pluge, not plunge!) is to help correctly adjust near-black. By its very nature, it's no surprise at all that what you see is black and indiscernible.

You will need to be (a) in a completely pitch-black room, and (b) very important, allow your eyes 10 minutes to adjust to the dark. This is a chemical reaction in your eyes which cannot be sped up.

LG oleds have two settings, "oled pixel light" and "brightness".

I guess I will try increasing pixel light to see the bars better.

MisterTickle commented 2 weeks ago

That would be wrong - "brightness" is what this pattern is designed for tuning. Oled Pixel light is something else. To see the bars better whilst you do the adjustment, there is literally no shortcut to (b) above and (a) is very important too. Good luck!

I tried your suggestion

the results were brightness 50 and brightness 51 both show the patterns correctly, with 51 being slightly brighter. brightness 52 goes over the threshold and shows 0.

In this case is 51 more correct than 50?
