I got my new Hdmi cable yesterday, it is the cheapest one atm to get a simple hdmi connection. Compared to the vga i ised before it is not as sharp/good. But at least now i can hook up my Dreamcast without issues with all tvs.
The image quality is slightly worse compared to vga, another small issue (at least for me its small) is that the image gets cut off at the top and button , and i can not adjust that via my tv. Its not by much (circa 1-2% top+bottom) but its there.
Would i recommend it ? If you want a cheap hdmi solution yes. It was the Hyperkin brand.
