ah. i guess this sounds naive of me to ask. is there any 4k upscaler? im guessing its impossible to go from 1080 to 2160.
There are plenty of 4K upscalers. They just all tend to require a lot of processing power, time, and a LOT of hard drive space. Frankly I don’t think there’s much point, especially since 1080p already looks great on 2160p displays, unlike 720p on a 1080p display (which can look fuzzy since it’s not an integer scale).
