Why is my Dreamcast displaying tiny with a new HDMI cable? (infosec.pub)

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.

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.
