We're getting awfully close to recreating CRT qualities with modern display panels. A curved 4:3 1000Hz OLED panel behind glass, and an integrated RetroTink 4K with G-Sync Pulsar support would do it. Then add in a simulated degauss effect and electrical whine and buzzing sounds for fun.
>1000 Hz
This sounds like a brute force solution over just having the display controller read the image as it is being sent and emulating the phosphors.
still can't play duck hunt on it though.
