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.
TVs didn't used to be that big, so your Dreamcast is pushing the biggest size available at that time.
Nah, I'm just kidding.
It is essentially what is going on.
