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.
It’d be cool if coreboot supported the Deck. Hopefully OpenSIL will help with that.
