I think I have only ever wall mounted one 4k screen and it was perhaps the end of last year. It was a Samsung it had this on it to connect to the screen.
Hmmm, I thought although this was nice in a way.. There was no VGA connectivity and although you can just use an adaptor connection for DVI to HDMI You cannot do that for Analogue RGB. Whilst they serve component and composite sources as Video standards backwards compatible. you can get an external active powered box to convert to HDMI from VGA probably a Analgue to digital convertor chip.
VGA is definitely being dropped from the market place when many people still use it and don't want the extra costs.
I Had to put the screen on the wall but you can imagine all the mess behind the screen that was visible from this thing all stuffed up behind as the TV has no inputs on it!!!
So who has the HDMI 2.0 connection on there 4K set and who does not? and who has a Full HD set with a HDMI 2.0 sockit and who does not?
Here is a snippet from an article.
First, here's where we are now. The until-now most recent version of the HDMI specification was version 1.4. It specified a number of things, like 4,096x2,160-pixel resolution up to 24 frames per second, or 3,820x2,160 up to 30fps. If you've bought any gear with an HDMI connector in the past few years, it's probably version 1.4. It carried over all the features and support from previous versions, plus added 3D , Audio Return Channel, and so on.
2.0 for 4K
With the TV industry moving inexorably toward Ultra HD "4K," it was clear there needed to be more bandwidth in the connection to handle the future's higher resolutions and frame rates. On that front, HDMI 2.0 delivers, supporting "4K" (2160p by the Forum's explanation) up to 60fps. This allows for full-resolution 4K 3D, along with higher-frame-rate 2D content, like (potentially) home videos and computer games (PC, not PS4/Xbox One). Since almost all movies are shot at 24fps , this increase is less important for feature films or scripted TV shows.

Also don't get me started on all the stupid flimsy graphics Adaptors on Laptops now and everything is becoming out board connections that easily break or get lost or the cable is damaged or the end on the laptop plug shears off. It's yet another minefield of problems.
Anyway if I connected a 4k blu ray player to a full HD set would it just pump out full HD down a normal HDMI and down scale or would I have to have gear that was HDMI 2.0 compliant for it it to work at all?
I have never tried it so I don't know.. I guess we will find out.
