Here is my current retro setup monitor. Being in the US it's really hard to find RGB capable displays, most PVM/BVM monitors are too small for my taste and people around here want crazy money for them. I took a chance a few years ago and picked up a 27" Mitsubishi AM-2751A for $50 off some really nerdy middle aged dude on craigslist who looked like he was stuck in the 80s. The MFG date is May 1990 and yet the tube condition is nearly brand new. It'll do 15khz all the way up to 800x600, albeit somewhat poorly. Still--impressive for 1990!
It really needs a recap but there's like 4 boards and a zillion caps in this thing for whatever reason and I don't feel like it. I tuned the adjustments when I got it but I was never happy with it, and the color/geometry pots were loose, so rotating the monitor a while back screwed up my adjustments. I had some time the other day to open it up and fix most of the issues with it. The geometry isn't perfect but it's good enough, corner convergence is decent, the color is good now as is the purity (fridge magnets!) and all adjustment pots have small hot glue dots holding them in place. I think it looks nice, despite being an old shadow mask tube. Very arcade-like.

480p performance (nothing amazing, but decent enough)
