The RetroTINK-4K is the latest evolution of the RetroTINK line of video line doublers and upscalers - and it's a gamechanger. It comes bundled with so many different options and it will handle just about everything you throw at it. But it doesn't come cheap at $750 USD. I've spent the past week testing one out and I wanted to share my thoughts in this comprehensive deep dive with many different systems tested. Big thanks to Mike Chi for sending one out for me to take a look at on the channel. Please enjoy!
