Interesting review IMO, with colour accuracy comparison and benchmarks of DeckHD vs. original screen (and other “known good” screens).
I would be more tempted by an OLED screen upgrade, but colour accuracy looks pretty good tbh. Pricing is in line with an official (matte) screen replacement from ifixit - $99 USD.
Higher DPI can improve text rendering. I want this screen specifically for small text. It also doesn’t force you to render everything at 1200p, you can choose to render some games at the old 800p depending on performance or scaling.
