OLED uniformity thread

[pingpong]

Dead pixels won't be visible in pictures from 4-5 feet. You have to be really close to see them. I can spot them starting from 3 feet.

Panel hasn't arrived yet. They are saying tomorrow or day after. Pfft!

Oh, then I have to check my panel closely for any dead pixels.

How's the uniformity of the new panel? What was written on the box? Was B9 specified or was it just a general OLED panel that's same for C9 and B9?

That's pretty good tbh. Keep it. You can get a lot worse. Take some free gift or something from the dealer if you can. Lol

Check colored slides, especially red, to see if there's any burn in.

No. Just these and then regular usage to ensure there's no coil whine from the power supply. It's tough get a 65 inch panel cleaner than this. So I hope it works well.

With a 5% like that, you don't even need to test 10%, 15% or 30%. White tinting seems fine too. Some gradual change is unavoidable, also because of the reflection filter. Don't see any major issues in the picture. Just check colored slides for burn-in.

Are you using the picture settings mentioned in first post including keeping oled light at 35?

This tests seems good to detect any vertical banding in our tv

I used the default out of the box standard settings

Test with the settings in the first post. That ensures all photos are directly comparable. Plus, default brightness is higher, which can mask the issue. Test with those settings for a better idea.

Yes thats why i asked you, your 2% percent slide has 3 bands visible in the center. But nothing visible in 5% and higher and in default Standard mode most sets look uniform.

Use isf dark mode with OLED light at 35 or 25, then banding will be visible.

Not sure what's the gamma in standard, but in the first post, gamma is 2.4 or BT. 1886, which are darker and will reveal more banding. Good catch, Gaurav. I jsut assumed it'll be in line with that. Lol

Ok so this is how it looks. Guess Not visible in standard mode

Ah! Now it's just average actually. Check some of the scenes mentioned in the first post to see if it's visible. Do this in a dark room for best analysis.

You can actually try your luck and replace it. Shows why it's important to stick to the same settings. Otherwise it's comparing apples to oranges.

I tried playing the Marco Polo scene mentioned but in HDR the isr dark room mode is not available.so picture is bright and vivid and I don’t see any banding
