While I was on paternity leave, I fell into a rabbit hole with YouTube channels like My Life in Gaming and Modern Vintage Gamer, and websites like RetroRGB and Video Game Perfection.
For those of you that aren't familiar with these guys or what they talk about, they're interested in getting the best picture possible from older/retro consoles on modern HDTVs. Consoles before the sixth generation (PS2, Xbox, Dreamcast, GameCube) usually output at 320x240 resolution, which most modern TVs either don't support or don't display well. You need a battery of speciality devices and high-end cables to get crisp, accurate visuals on digital screens with no additional input lag.
There's a bunch of retro gamers here. Have any of you messed around with this stuff? Do you have older consoles hooked up to newer TVs, or keep an old school CRT hooked up for all your retro stuff?
I found it all really interesting, especially when you start learning about the lengths people are going to in order to modernize retro hardware. There are modders out there that will add HDMI to a Nintendo 64, put Bluetooth in a Dreamcast controller, or replace your Saturn CD-ROM with a SD card reader.
