Alternative hardware for high refresh rates

[devRomeos]

Hello, I am studying the best option for my project, I plan to use only a single 32x32 panel , but 3840hz and I want to avoid the black bars when you take a daytime picture, also the "dizziness" when you turn your head quickly.

What I learned here it's that esp32 it's way too far to archve that refresh, even for a single color . Not sure if this is the place to ask this but I wonder if there is out there any other hardware or card that can handle my needs, just want to show static 4-5 bits images, and change it on demand

any feedback is welcome

3840hz will need a fpga or a super low colour depth

Hum, do you think I can get atleast ~1500hz with 4 bits images? I had tried the spreadsheet calculator but the refresh rate it's always stuck on 143hz

[mrcodetastic]

Ckock speed in hz (Mhz) / 32 / 32 / colordepth^2

Should = refresh rate

[mrcodetastic]

Work backwards from that

Gotcha, thanks !
Asuming 20Mhz with 32 x 32 total pixel at 3 Bit I get 2170hz that might be enough

Anyway, if some body know any other hardware or chinese card where I can do this in a more fast way let me know, I only need to push an static image from time to time, sending the change command by UART or something

Actually, I might be wrong, what is the "scan type" of the panel?

1/16? Which means two parallel scan lines at the same time.

If so, then one of those 32's in my equation should be a 16.

So double the refresh rate.

I don't have panels on my own yet as I'm researching before take action, the panel I am considering are 1/4 and 1/6, does that mean it would be double the double? 😚
