I’m gonna get downvoted to oblivion for this…
I just got my new OLED and weirdly enough, upon booting it I saw something that I didn’t even think of till now. With the new OLED, the sub-pixel arrangement is slightly different than the LCD, and it’s causing white edge (specially on text) to have this green/magenta fringing. It’s extremely faint, and it’s not particular to the Steam Deck since I know of other OLED panels that have the same fringing. However I have heard zero mention of this and I have to say that although this matters close to nothing while playing videogames, it’s something I do see with subtitles.
With this out of the way, the screen looks amazing and I’m more than ready to sell and replace my LCD deck now. I hope the technology gets there where this isn’t an issue anymore!
Probably because SD screens are designed as vertical screens and are used horizontally. If you ever boot into bios or check screen orientation in display orientation you’ll see signs that hints to this.
