Good idea, but I noticed some issues:

IMHO it would be useful if at least the result pages had permalinks so you could copy and share them.

I think the adapter suggested for "laptop with VGA" to "TV with HDMI" does not work that way around, which is exactly the kind of mistake this site should help to avoid.

As others have noticed, (m)DP is fairly important and missing.

given the watermark, you are probably not allowed to use this image on your site in this way https://www.dongledaddy.com/images/tv/hdmi.jpg
