DeckHD is a new custom screen mod for the Steam Deck. It promises improved color accuracy and a 1200p resolution increase. In this in-depth review, we cover ...

Summary of the main points:

  • Requires a custom BIOS, and it is not known (except for DeckHD) how to patch the BIOS. Future Valve BIOS will break the screen support and one is at the whim of DeckHD making patched BIOS in the future.
  • It is still possible to switch the resolution to 800p.
  • Can lock at 40 fps, but…
  • Spider-Man Remastered and Elden Ring will only reach 30 fps at 1200p, Final Fantasy XV 25–30 fps, so 40 fps lock is pointless.
  • 87.8% sRGB, 6258 K CCT (noticeably warmer) and γ = 2.12, vs. 71.9% sRGB, 7900 K CCT and γ = 2.11 of the stock LCD measured with Calman.
  • 439.5 cd/m² (noticeably darker) white luminance to 0.514 cd/m² black luminance, hence 854:1 contrast ratio (less contrast), and vs. 536.6 cd/m² to 0.507 cd/m², 1058:1 stock, and a darker game like Resident Evil 3 seems to suffer.

    Thank you for the roundup, I was considering it after seeing a friend’s Ally screen (and feeling jealous), but that brightness hit, and the custom BIOS is a hard pass from me at this stage
