I have never written a review before on amazon (at least I think), but this HDMI converter was so impressive that it's worth leaving one for.
Works seamlessly on a modern PC monitor and outputs amazing audio and video with no noticeable input delay.
I've used AV converters before that cost twice as much and leave noise and artefacts, but this is truly as close as you'll get to perfection without using a HDMI mod on the Dreamcast console.
A solid 10/10 for me, I'm definitely looking into buying the same brand for my original Xbox also.
