Thanks for infoIts complicated.
1) HDbaseT has different version chipsets and different partner compression/uncompression chips. So its really only 100% compatible with the TX and RX match on both these fronts. You'll most likely still be able to get some sort of video if they don't fully match, but the feed won't be reliable, or it will be limited to a certain resolution....just overall not a good idea
2) Different HDbaseT kits have different power requirements. Some brands use 24v 1a or some use 12v 2a. Given the fact that most HDbaseT kits use POC (Power over Cable), you could fry either the TX or RX because one of them is sending the wrong power requirements to the other side.
Thanks for info
Another factoid to consider is that video is still compressed via HDBT until the latest Valens chipsets are made available (VS3000). HDBT Spec 3.0 is the latest version but whether there are devices shipping with that spec or not I don't know. And I agree with the above, keep the tx and rx the same. Don't mix and match. It also helps if the cabling in-between is solid copper core UTP (non-CCS/CCA and not pre-terminated ethernet) cable.
