Displays for Retrogaming

[Bumblebee]

Hey All,

I've been looking around for portable displays (such as EYOYO on amazon (12" Display) 4:3 AR https://www.amazon.com/Eyoyo-Monitor-1366x768-Portable-Display/dp/B01KJVERF8/ref=sr_1_5?crid=1XGB9NRO08NFD&dib=eyJ2IjoiMSJ9.v7Xo_BmqmMAB9IfkDg0GePxK3WWo0NSldwY16w4W9DTZcLokV7VcyZYqtjDaZqdiSxQTmBmjYg4mcm6ENg9YbSfNtI2keiwegPaSyTGmw0kX5Cpdy5m-MPlYIpdXPKEgHv-8TBXLBO5MSOjU15HudkhNYX8C-x_vKGgya7fquyATx1mZItBWRA8BihWTZZuWDPIXGcoy7bgMQQM3XLGcpKbLHtLdH0_6Qrkp45Y7zbE.2PGPzoxb7ksZzhoh2AgQDIkaUdaYm2DLmQY4qHU8TgE&dib_tag=se&keywords=EYOYO%2BGaming%2BDisplay&qid=1727862773&sprefix=eyoyo%2Bgaming%2Bdisplay%2Caps%2C80&sr=8-5&th=1) 

for retro gaming. My ultimate question after finding a youtube video that the following aspect ratios are great for retro gaming: 

4:3
8:7
3:2

Can someone tell me if there is a monitor that supports all of those? I am just looking for an all-in-one solution, so the games I play, whether through retroarch or a stand alone emultor will run them in their true glory if you know what I mean. No Pillow Bars (black bars), at the top or bottom of game that is running. If not, anything close in terms of a monitor? I don't really care what type of monitor it is, I am just looking around for now, but looking for an all in one meaning all those AR's can be changed on one screen. Meaning in the settings, I could choose 4:3 8:7 or 3:2 aspect ratio and play the game in that AR.
