@Deadeye I'd say I'm fairly flexible. 14' or so sounds good to me. I'll be fairly close to the screen. I have a SNES and N64, both RGB modded, and SCART cables for both. I also have the HDRetrovision cable which they both can use.
My goal is simply to be able to use my SNES and N64 on this TV which will be hidden away in the corner of my bedroom. I want a lag-free and good looking experience. High quality for sure is a must, though I am not looking to spend a grand if I can help it.
Ideally as "plug and play" as possible. I'd like to avoid having to buy some sort of adapter.
Extra nice to have: If I can play PS1 on it as well that'd be lovely.
