Not sure of your preferences of PS2 video output, however there's the pimoroni 8" it's pricey and only has HDMI in. Or there's HE080IA-01D it's also the same 8" 1024*768 but it has the smaller driver boards with HDMI VGA (no 15 kHz) and composite. I'm still waiting on my pair to come in but they aren't too pricey.So I've been overhauling my PS2 portable recently and I've just got to know: What is that screen! Frankly I'd love a 4:3 solution with a smaller driver board than the Eyoyo 8"

** Actually just realized that driver board in the previous photo is the one on the 8" I linked
