So, I have a question...
Would it be possible to implement a firmware feature (by HD Fury) to support nearest neighbor scaling? I've been searching far and wide for a method to upscale an HDMI source using integer scaling WITHOUT filtering. I understand that, for film content, filtering makes sense but I use this for game and game capture purposes (partially for my job at Digital Foundry - where we focus on the technical side of game coverage)
Taking a 1080p image (or, if it were supported, a 720p image) and scaling it to 4K would be perfect for many games.
Here's an example - this is a direct-feed capture from Nintendo Switch's portable mode (using a modded system). The viewer allows for nearest neighbor scaling. The result here is a perfect 2x2 scale from 1280x720 to 1440p. A 3x3 scale is also possible for an exact 2160p image. I cropped this a tad for better viewing on the forum but you can see the result - perfectly sharp pixels. Up close this may not be super desirable but, from a normal distance, this greater increases the perception of clarity and sharpness. No ringing artefacts and no blurring.
(simply drag these images to the address bar to see them at full resolution - this forum scales them down automatically)
For comparison, this is a cropped image of a 4K capture from the HD Fury Linker with the Switch itself outputting 1080p. This is a pixel art game set to "no filter" mode so the output should be super sharp and crisp (the PS4 Pro and Xbox One X versions support this internally and output razor sharp pixels). The HD Fury, however, blurs the image as does virtually every other TV on the market when upscaling a 1080p signal (aside from one uncommon Panasonic TV which also exhibits high input latency, unfortunately).
So, basically, what I'd like to see is an option to completely eliminate any sort of blurring during the upscale process. Nearest scaling should be computationally cheaper as well. Unless, of course, this is a hardware limitation on the Linker side.
If not the Linker, has anyone else discovered a solution that fits the bill? I haven't been able to find a single option that delivers this.
