My gaming set-up

I've been working alone over the past few months to configure gaming set-up with minimal input lag and no degradation in video quality. I plan on hooking all of my video gaming consoles up to 2 monitors with surround sound. So far, I plan on hooking up a nes, snes, phillips cd-i, n64, ps1, gamecude, ps2, wii, ps3, wiiu and ps4 to a benq rl2755hm and a samsung un65ju7500. I don't want to mod any of my systems, since these are my originals and I'm ok with only going to s-video instead of rgb for video output on older consoles. I will try and explain my set-up with links to the products I will be using.

I've been searching for a few months for currently available s-video and component switches and can't seem to find much. I haven't heard much on shinybow, but what I've heard hasn't been particularly good concerning quality. If anyone has any suggestions it would be greatly appreciated. Hopefully, I'll be able to start testing this rig in the next 6 months, once the part start coming in.

Thanks,
Frosty
