Comment on Why is my Dreamcast displaying tiny with a new HDMI cable?

  If your TV has a crappy upscale then you can look into external hardware, however seems odd this is making it choppy, does your TV have a low latency GAME mode?

    With this cable it’s getting the signal as vga, so it’s “pc” settings. No lag or anything. And I meant choppy like lines and such. Should’ve said “crispness”. The game plays flawlessly on the tv with no output issues.

    Sorry for the confusion.

      Yeah, as said, that’s going to be due to however your TV upscales things.

      Getting a dedicated scaler will help, but bear in mind that you’re taking an image that’s at least 1/4 smaller (might be less than that, can’t remember the math off hand) than your screen’s native resolution and zooming in on it.

      Using most scalers gives you a ton of options for how to zoom in. Straight pixels, bilinear (or trilinear) filtering, and some have various shader effects as well to emulate the style of TVs these consoles were made for.

      By using HDMI/VGA you are getting the clearest digital signal version of that image possible, but it’s still tiny, and any way you choose to expand it will have pros and cons.

      You probably need to take a picture, you might be describing that the output is 480i interlaced where every other line is drawn and some modern TVs will render that badly.

      Take a look at this link some games support 240p output mode…
