OLED screen quality

System: Windows 10
Battery or AC: AC
Description: OLED screen quality
Model: Asus Zenbook Pro Duo
Frequency of Occurrence: Always
Reset OS: No

I bought Zenbook Pro Duo and the first thing that caught my eye was the uneven backlight of the screen. When displaying e.g. 5% gray, using a video on YouTube at this link https://www.youtube.com/watch?v=Qi4Wy7vE8-o&t=124s and reducing the screen backlight, you can see a large unevenness in the brightness of the backlight. I will point out that the problems I describe can be seen best in a dark room, when working during the day the problems are not visible or are very poorly visible.

Banding? Do you have grain too?

First of all, OLED screens, like the main 15" screen of the ASUS ZenBook Pro Duo, do not have backlights. They are emissive displays where each pixel produces its own light when activated. That being said, you should be seeing a solid image with a solid screen like that of the 5% gray video that you linked to. I tried it on my Pro Duo in the dark and did not notice any difference in the illumination of the screen even at low brightness settings. If your screen looks normal in normal viewing conditions, I wouldn't be too worried about something that only occurs in the dark at extreme settings that you're not likely to use anyway..

Read this. It's same panel and show same problem ( https://www.ultrabookreview.com/29145-dell-xps-15-7590-oled-review/ ) Your photo is not clear about grain. Your screen have grain in gray/white background?
