Why is my Dreamcast displaying tiny with a new HDMI cable? (discuss.tchncs.de)

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.

And I meant choppy like lines and such. Should’ve said “crispness”. The game plays flawlessly on the tv with no output issues.

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..
