Unlike DeckHD, the team at JSAUX decided to stick with the normal 800p Steam Deck resolution. The only minor difference is that JSAUX claim their screen has 70% sRGB coverage versus 67% on the original. Could be a good little upgrade mod for anyone with a 64GB or 256GB Steam Deck to get the anti-glare screen.
A difficult mod to do though, that requires taking the entire Steam Deck apart. Not something beginners should think about, as a lot of small things can go wrong that could end up becoming a big expense. Even the JSAUX store page has a warning on this (nice to see).
Still, it's nice to continue to see more and more hardware mods appearing for the Steam Deck because of how open it is.
Available for $89.99 via JSAUX.
