So I've done the first optical test and the 4 x 1440px solution fails. I have concerns about brightness (and size) of using 2 x 2160p screens since I'd expect <200nits to the eye. I'm going with 2 x 2560px screens as the 2 drawbacks are its high cost (£500) and 75Hz (when over 1920x1920/eye) refresh rate, but is otherwise an ideal choice.

From trying different screens, I can say that:
- 70ppd looks pixelated and annoying. Must avoid.
- 80ppd is on the edge of looking pixelated. I'd like to avoid because I'm always going to be squinting, thinking "can I see pixels?".
- 90ppd is a nice balance of sharpness and Windows GUI at 100% scaling.
So it seems that 100ppd would either be ultrasharp or just indistinguishable from 90 if I extrapolated it, and that increments of 10ppd make a very noticable difference until getting to my eye's resolution, so I'd rather not imagine what Nreal Air and its 50ppd looks like.

I will admit that a notable reason why I'm starting this project is because of some issues with #Teti [gd0022] and its 3 screens. I've had them since Dec 2020, so I know of the challenges and limitations, which are:
- There's only 3 screens. I can store extras away when I don't need them, but if I'm really in the zone, programming something mystical like #enSweepen [gd0096], I might want 4 or 5. The only solution would be to move closer to the screen and reduce the scaling percentages of them all to fit more content.
- They weight 800 grams each. That's 2.4kg of screens to be carried inside #TetInventory [gd0039], and somehow needs to be held in place by a hinge on Teti.
- 9:16 is a very tall aspect ratio for portrait mode viewing.
- I don't like screen light coming in via my peripheral vision. It's a leading reason why I've gone with a stacked monitor setup for Teti.
- They have different white balances. I didn't expect this because they look fine by themselves, but when I turn on all 3, I can see that one is slightly bluer than another.
- They're small. 15.6" is a decent size, but I've longed for a 17.3" or larger screen.
- They're large. I know what I just said a bullet point ago, but there's still a lot of glass surface area that might be impacted or scratched one day. It's also pretty tough to hold one handed since glass doesn't have a suitable level of grip.
- They're a bit of a "black box". If they break (I've already got a stuck green pixel on one), I wouldn't really know if I could get parts to fix it or have the skill to not break something else while doing so. The firmware on them also has this annoying blue "no signal" screen that has annoyed me for the 22 months I've had the displays.
- They're 60Hz. I'm glad I went resolution over fps back in 2020, but I'd very much prefer higher Hz.
- There's no privacy. I can only imagine how curiosity inducing I'd look whilst sitting somewhere with a complete 3 monitor PC setup. Additionally, IPS panels have great viewing angles, so pretty much any 170 degree angle behind me is visible.
- Speaking about visibilty, they're glossy, meaning that anything behind me that's not dark coloured is going to reflect off the screen.
- I need something to place the screens onto, which limits the comfortable viewing positions possible.
- Tetent might not be ergonomically compatible with the dual screen laptop configuration idea.
TyMist can solve all these problems (and others, such as other things like protecting my eyes from bright light sources), and currently, it seems less complex than I originally estimated to obtain a solution.
- I can have much more than 3 screens, and I won't even be limited by the minimum angle due to the length/width of the screen. I could have 5 screens yet my neck only needs to move the angle of 2.
- I fully expect that a HMD isn't going to be 2.4kg in weight.
- 3:4 is a comfortable aspect ratio for portrait mode.
- Only the active screen and position markers for windows on other screens...
