Picked up a Hyperkin Dreamcast cable that outputs via HDMI. I tried it out and it’s displaying in this tiny box on my TV. The box on the cable has no settings and the TV is a 1080 Sony Bravia.

I’m not sure what options I have aside from stretching the image via the TV settings but if anyone can assist, it would be appreciated. Thanks.

    I was using an RCA cable output prior to this. It worked great, though was lower quality of an image than I would’ve liked.

    I’ll have to check the display mode on the tv and see if any other options exist. I did play it in Fill mode which kept the 4:3 resolution but I feel like that sorta defeats the purpose of using hdmi.

      HDMI doesn’t automatically mean good resolution. The Dreamcast only outputs 480p. That’s regardless of what you’re using to plug it in. The TV was likely automatically scaling the RCA signal, but isn’t scaling the HDMI.

      Well no? You are getting a digital signal which will be MUCH clearer than analog RCA… Upscaling / fill mode is the Only way to make it bigger.

        You’re right. The picture is cleaner but choppy not crisp from TV being set to Full. That’ll have to be my Solution for the time being.

          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. In which case it is a deinterlacing issue.

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

      If your game isn’t 16:9 then your video won’t be. Nothing about HDMI means you’re automatically going to get high def widescreen.
