As far as I know, 4:3 OLED screens in the size of a conventional monitor don't exist.

This apparently came up during the development of the Checkmate LCD monitor. They looked into the possibility of OLED panels, but they would have had to been custom made and require a minimum order of 50,000 units.

If you want to see what is available, you can always check https://www.panelook.com/

On Amazon and other pages you can see industrial 4:3 TFTs and they all advertise 75 Hz and fast response and IPS.

I'd be careful about screen refresh rates being advertised. Some monitors advertise support for 75Hz, but that doesn't mean the panel itself can display 75 Hz. Some of these monitors may achieve this via frame skipping.

Even my current LG 38" ultrawide monitor does this. It advertised up to 75Hz, but the panel only runs at 60Hz.

I think I have a mission now. I need to find 49999 other friends to so we can place the order.

I don't understand why nobody can't just build a 4K 4:3 monitor with built-in CRT screen shader software...

Because the panels don't exist.

edited to add: Slight correction in that Arcooda does offer 26" and 35" 4k 4:3 displays. However, those are designed for arcade usage and not for desktop PC.

There is a 1440*1080 IPS monitor that does 15~31khz , it was tested on RETRORGB site: https://www.retrorgb.com/arcooda-26-43-lcd-ar … tor-tested.html
maybe it is of interest

Arcooda is one of the few companies still focusing on retro displays, although their focus is more on arcades.

They are apparently working on a modified version of the Checkmate monitor, except with their own panel and internals. They'd promised specs back in March, but no updates since.

Last I heard, the tariff situation with the U.S. had a significant impact on their business since they are an Aussie company and the U.S. is a big customer.
