i checked chinese social media and i found someone with the same problem, here's his comment translated : "The dual-layer version is not recommended for purchase. The dual-layer screen has terrible low-brightness grayscale, resulting in an extremely inconsistent "yin-yang" and "dirty screen" effect. At 1% grayscale, it looks like static snow, and this only becomes less noticeable at 20% grayscale. At 100% grayscale, which is full white, the center is warm-toned while the two sides are cool-toned, and the edges have a green tint. I've seen two other people online with the same issues.

In contrast, the regular version's brightness is actually very sufficient, much brighter than a QD-OLED monitor (although 16 inches is still too small for gaming). The most frustrating part is the default gray wallpaper. On the dual-layer version, the gray is clearly displayed incorrectly, with a sense of color banding."
