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!
Unfortunately this happens in most low pixel density OLED screens, unless they are Super AMOLED Plus (or at least that’s how Samsung called the version of OLED with a traditional and regular RGB subpixel arrangement, I think they only used it in the Galaxy S II).
The diamond subpixel arrangement definitely minimizes this effect, but probably doesn’t work too well for low pixel density screens, since it’s primarily found on mobile phones.
