[Searching] New screen for mounting 3 MFD's horizontally

Hello all, I have been making some plans towards building up my own cockpit setup and create a sort of minimalist sim pit. My current setup has a nice combination of a large and small screen so that I can mount 2 MFD's (or remove them to open up the screen for Discord and such):

I am looking for a new screen that I can use to mount 3 MFD's in a horizontal fashion (side-by-side). Similarly to my current setup I do not wish to have a full-size 2nd monitor, but instead something smaller.

I have been looking on Amazon to find Piece of Sales (POS) screens of desired small size and widescreen, but have not been able to find anything yet that seems to fit 3 Thrustmaster MFD's next to one another.

The screen size should minimally be 387.2 mm wide, with a height of 141.2 mm (preferably with a wide bezel and HDMI input). Are there any screens out there that fit these specs?

I mean whatever size the monitor above is seems to be a good size.

A 25 class is probably going to be the smallest Ultrawide panel you'll find.

I got myself three Lilliput 8" touch screens and a powered usb 3.0 hub. Never looked back. I use the touch function for extra controls through Helios.

Quick play with the dimensions of MFD listed on the diagram on here suggests you'd be looking for a monitor about 400mm wide.

Plugging that into here suggests an 18.5" 16:9 monitor might do the job

There look to be a reasonable number of cheap monitor out there of that size but they tend to be low resolution - 1366x768 or so - which I think would give you something around 350x350 pixels for each MFD
