The purple device is using DeckHD.
I spent the last month testing the DeckHD mod and the various configurations that the team created for their display. If you were thinking of doing this mod yourself, I have some advice that might help you. I can also try to answer any questions that people have.
General Stuff
This mod is pretty involved, so you should plan on the entire thing taking about an hour to complete. The kit comes with a suction cup that is better than the ones that I’ve seen in some of the shell mod kits, but there are better suction cups that you can buy that would make the entire process way easier to do. They priced this at $99 (without discounts) and it comes with the same surface type as the 512GB Deck. This puts their kit in the same league as the official kit from Ifixit, but that kit comes with slightly better tools. It is a good idea to update to BIOS 116 before you think about doing this mod, especially if you have a Deck that uses an unsupported BIOS (114).
The Good
The upgraded screen does improve color accuracy within 1% of their advertised specification. In a random selection of games that I picked, there were many instances of colors that were completely absent from the stock Deck that are visible on DeckHD. These colors are usually purple or magenta since those are the least accurate colors on the Steam Deck screen. Other colors that improve are green & blue (to a smaller extent) and red. Overall, the color accuracy increased by about 16%. Their original marketing material had this value in the 25% region.
Every feature of the Steam Deck screen fully works on DeckHD, including changing the refresh rate down to 40Hz. I didn’t notice any screen flickering issues changing the refresh rate or the brightness. The minimum brightness level is also exactly the same as it is on stock.
The Deck does have the ability to play demanding games at 1200p, and you aren’t limited to very old games for this. As a general rule of thumb, most modern games that run near 40-50 FPS at 800p will be around 30FPS with this panel. If you don’t want to use the added resolution, you can just stick with 800p as the default setting for all titles.
The Not So Good
This mod requires the use of a custom BIOS to function. This BIOS is installed by the user in desktop mode. The team hopes that they will eventually get official support from Valve, but it’s better to view that as something that will never happen. BIOS updates don’t hit the Deck that often, but you’d need to hope that the company continues to push out modified BIOS updates going forward. I would hope they would open source the changes that they need to make to the BIOS so this could be done by the community if the company drops support for this screen in the future.
The color temperature of the new screen is not the same as the Deck. It’s significantly warmer. If you look at a white picture on the Deck and that color looks “normal” to you, then this screen will seem a little strange until you get used to it. If white colors look too cool for you on your Deck, then this screen will be an upgrade.
The maximum brightness of the current retail screen configuration is -100 nits from the stock Deck. This is about 75% brightness on stock, so you can use that setting on your own Deck to see how it would be.
The screen uses about .5W-1W of additional power and it also generates slightly more heat on the right side. This could be the result of many things, but it’s important to note that the back of the screen does not have a full sheet of thermal film like the stock screen.
There are occasional times when you’ll wake the screen up and the entire screen will be white. To fix this, you just have to sleep the device and wake it back up again. No idea if this can be fixed long-term, but it is very rare when it does happen (I’ve only seen it a few times in the last month).
Finally, they do have another configuration that is not as warm as the retail version. That one has almost the same color temperature as the stock screen, but it comes with much higher brightness and better contrast. Some things won’t look like they are a direct upgrade over the stock screen due to the RGB balance, but it is a more obvious direct upgrade over the stock screen without looking strange. They have that configuration, but I don’t know how others would get it.
