Are there any AV receivers that will allow me to cleanly integer scale any popular resolution (240p, 480p, 720p, 1080p) up to 4K or 8K?

    Just passthrough 4K and do the scaling on your own via software. Wouldn't make sense to have a built in scaler use the worse scaling imaginable.

      My use case is for video games, I want it scaled every frame

        Don't emulators do this? If you need it straight from a console you can probably still do what I said just via a capture card device.

          I'm concerned that passing through a capture card would add a lot of lag

            Pretty sure due to the rise of streaming they have low latency capture cards. You're going to get some latency through an AVR scaler anyway.

    Even software AI upscalers can only do a decent job upscaling native blu-ray 1080p to 4K. Anything less than 1080p causes the AI to hallucinate a lot of important details.

      I'm not sure why I'd be involving AI for something like this, wouldn't it just be multiplying the resolution and keeping the pixels in order?

        You'd just get pixilation at higher resolutions especially from 240p sources.

          That's what I'm trying to do. I know that I'm not going to plug them in and get it to look like Cuphead, I want something that will multiply the pixels and keep them square and uniform

            GPU upscaler should be able to do that on nvidia/amd when you go fullscreen.

              GPU scaler, that could be possible.

              OP, this is called nearest neighbor scaling, lots of output streams support it, what are you trying exactly?

              Nearest neighbor! That's the term, I thought it was integer scaling, thanks.
              For a specific example, I'm playing Demon's Souls on my PlayStation 3, which outputs the game at 720p. My LG TV is 4320p.
              I want to be able to multiply each pixel of the PS3's output into a 6x6 grid so it'll fit cleanly into that 4320p image.

                the lazy /buy/ way, it'd be impossible to know which product would work for you as far as latency goes.
                frankly it sounds like you want an FPGA with HDMI in and out, that's the only """guarantee""" I can give you, but I'm not sure if you care for the amount of work.

                No that makes sense, it's a very niche thing. Thanks for the answer at least.

                This seems like a silly endeavor considering that you can't turn off all of the post processing TVs have anyway.

                The closer to the perfection the better. And most post processing gets turned off in game mode.

                There's some expensive upscalers that can do it with very little lag, though I doubt any that can do more than 4K. >>>/vr/ usually has a thread about them.

                Could always emulate.

                The emulated version is fantastic but there's something special about the original systems. Thanks though, I'll hit up /vr/

                I don't think consumer tvs will have an option choosing between different scaling strategies, so not sure how to proceed here in an easy/accessible way

                the lazy /buy/ way, it'd be impossible to know which product would work for you as far as latency goes.

                what this guy said would work but it might be out of scope for your scenario, you'd need some kind of specialized hardware inbetween for no latency
                Maybe look into some custom made retro emulator stuff? they may have some premade solution for that
