How can I get retro consoles playing on a tv with only HDMI?

BenRC

Wife got me a bunch of retro consoles for Xmas, thing is my gaming tv only has HDMI and nothing else. I need to connect a few RF, scart and rca leads.
Is there a one stop solution that means I can have them all plugged in at once via some sort of switch? Tried the cheap chinese rca to HDMI jobbies off eBay but they're pretty naff tbh.

You can buy Scart to HDMI converters. With most consoles (say Megadrive, Master System, SNES, Saturn etc.) RGB scart is the best image you can get. If you connect the RGB scart cable to a scart to hdmi converter, then you can just plug into the tv via HDMI. Some also upscale to 720p or 1080p. Here’s one from Amazon:

Thanks. I got one in the end and im really impressed with pixel based games. Polygon games don't really improve much.
