Not sure if it belongs here, but it might be of interest to some:
I needed an extra-long HDMI cable run for the new home theater setup I've been putting together, and after looking over all the options it seemed like HDBaseT would be the least-expensive and most convenient option - if it lived up to its claims.
I've never really seen much information on these devices from enthusiasts, and have been skeptical of them.
But I tried out an "AV Access" brand adapter which seemed to tick all the right boxes for my needs: Uncompressed 4K60 with EDID cloning (critically important), claims of zero latency, and as a bonus it also included USB. It does analog audio too, but you shouldn't use it (it's bad). A shame it doesn't have an S/PDIF connection as one of their other boxes does.
…and it works!
I got to check it with a lag tester today and I'm measuring 0.14ms delay.
The EDID management works correctly - so 1080p120 works. I wasn't sure if it would, since they only advertised 4K60.
And USB works for more than just keyboards and mice. They work like regular USB ports. I was able to connect controllers and even a USB audio interface, which all worked like they were connected directly to the PC. I'm guessing it's a single 480 mbps link.
It's not cheap, but I've spent far more on long cables and active HDMI/USB extenders in total, when trying to find a solution that worked in the past.
Being able to do this all over a single ethernet cable -which even carries power to the receiver- and for less than the cables I was looking at feels like cheating.
