I have a Retrotink 4k. I mostly use it for VHS transfer these days, but it's original purpose is upscaling retro game images and applying various masks and filters to make the game look like it's using a CRT on a modern display.

It works beautifully, and you no longer need a clunky, heavy, dying CRT. I'm sure the purists will say it's not the same, but I've done sides by side comparisons IRL and it's good enough for me even when pixel peeping. I prefer the emulated CRT look on a modern OLED to the real thing these days.
