[E1][T] Screen options

A project log for T^2 TyMist [gd0138]

I need some virtual desktop monitors that offer 90PPD at 90Hz.

I've been thinking over my options all day, and even scanned over Panelook to see if there were others I hadn't considered. I'd like to think of something else like the PCB of #Tetrinsic [gd0041], but it seems I sold the solution too well to myself and now my subconsious won't let it go.

Anyway, the screen options:

My initial thought is to make the CAD design somewhat option agnostic, so that if I initially planned to use one and then decided to use something different instead, I haven't hard-coded myself hours of rework. I'm also thinking of eliminating the 2:1 ratio options in favour of being able to switch from landscape to portrait desktops.

I have also finally found a video that has the black PLDC film option against light:

I've been worried for a few days now that the film was going to be too dark, but this seems to be fine. I also looked around for electrochromic glass that (eventually) tints, but I can't find any purchase locations:

I've been holding my 4k monitor at 40cm such that I get 80ppd, and I couldn't shake the feeling that 2160 seemed small and / or crampt, with thought phrases like "kinda compressed" or "kiddy edition". Changed to 2560*1920 and exclaimed "WOAH. SO EXPANSIVE". Thus, it seems that the 2160 option has been downgraded to CanDoTheTaskIsh, which is lower than the minimum required level, CanDoTheTaskApp.

If what I wrote in a comment last log is correct and I can usably beamsplit the 2160, it would be the most likely to work for the least cost. And CanDoTheTaskIsh is miles better than "CanDoTheTaskTheoretically" aka "it's a nice idea but I don't have anything that I can actually use in a reasonable time frame".

On that note, 2560 still seems to be leading as the best solution assuming I can order from Alibaba.

Quad 1440 has a lot of hurdles to overcome. For starters, one of the reviews said HDMI->DP doesn't work. I've been looking into MST hubs and solutions exist for 2 or 3 DP's through USBC. It wouldn't be too much of an ask to sheath 2 DP's and a USB cable into one larger cable. Then there's the size of all the optics. Get past those and I'd be left with a massive, 2880x2160, 120fps setup so the struggle is certainly worth it.

Me, looking at [https://www.aliexpress.com/item/1005003483742763.html]: Man, why is the control board £90? That's one of the most expensive driver boards in this Aliexpress industry. Probably because it drives 2160 @ 90Hz. Understandable.

The listing: "Refresh Rate of driver board is 40HZ."

Me: car_crash.sfx [https://www.youtube.com/watch?v=9QQGbu9wrF0]

40Hz is going to ruin that entire run. 2160 at 90Hz requires 10Gbps and the Toshiba chip I found only does 7.2, so it's not like I could make a solution.
