Touchscreens can have a negative impact on the image quality, which is also the case for some OLED models from Asus' ProArt series. The creator tablet ProArt PZ14, however, features a gorgeous 144 Hz OLED touchscreen without any issues. However, when you start adding a touchscreen, there can be issues with a grainy picture impression on brighter contents, which is a bit like a matte IPS screen. One big aspect is the supplier of the OLED panel, and older Samsung OLED panels in particular suffered from this problem. Samsung fixed this issue for its own Galaxy Book models by now, but Asus devices sometimes still suffer from this issue, just like we saw on the recently reviewed ProArt PX13 convertible, which is still equipped with an older Samsung OLED panel.
