There has been a lot of hype about the RetroTINK 5x-Pro because it does an amazing job up-scaling analog signals (composite, component, S-Video, RGB, & SCART) to a 1440p HDMI image. I think that technology sounds amazing, but I'm wondering if there is a device that allows people to upscale 720p HDMI gaming to 1440p or 4K. Like if I bought an Analogue clone system, set it to 720p, then used it to upscale to 1440p or 4K, that would be amazing for getting the most crisp image on a ultra high definition display. Does anybody here know of any technology that exists which can accomplish this outcome? If so, what are the best products on the market? Edit- It's also worth mentioning that I would want something that adds zero latency.
