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.

The peach on the author's CRT looks pretty awful, as does the photo. I'm curious what sort of CRT produced the meme image. Maybe it can't be done by a real CRT, but the author's CRT doesn't look anything like the example from the CRT database they have below.

They also said the impression is different since it's so close up - what does it look like at the size you'd really see it in game?
