Anyone Try 4K Wireless Yet?

I was just looking and came across this...
https://www.jtechdigital.com/j-tech-...ansmitter.html

Obviously the price isn't in the "HDMI CABLE" category, but may be a good retro option for those who aren't looking to fix drywall and have cabling run.

But, I'm more interested in whether anyone has actually used this and done any real world testing.

Feedback instead of 'options'. Though other wireless solutions would be interesting.

What I don't know, because they don't mention it, is if UHD/HDR is supported at 18Gb/s. They talk about 4K and 4K/60, but that doesn't guaranty 4K/HDR 18Gb/s as a option.

wifi is up to 300 mbps, 4K requires 12 GBPS and 4K UHD requires 18 GBPS. LG WebOS will stream what they call Netflix 4K UHD and I think it is a noticeable improvement but it is not as high quality as I get playing a 4K UltraHD disc on my OPPO UDP-205 to my LG e6p and audio from my Yamaha AVR TSR 7810.

So, wifi uses compression and decompression with a transmitter and receiver. The claim is the quality is equivalent but that is in the eye of the beholder. If all the lost data does not matter this claim could be true.

There are a lot of wiggle words and naive consumers.

Yes, I'm aware of the limitations of Wi-Fi and the rest. Wireless HDMI is often point to point, not sure if they are actually using Wi-Fi, or something more proprietary since they are almost always point to point solutions, and often range limited.

I'm really just wondering if anyone has used one a 4K solution for wireless, compared it with a cabled solution, and what their thoughts were on the product and actual results.

4/22/2019 Otto in another thread stated he has read a number of complaints about HDMI wireless.

Here is a review of various HDMI wireless solutions: https://wiki.ezvid.com/best-wireless-hdmi-transmitters I think quality takes a hit but there are a number of other reasons for using wireless HDMI which I did not consider.
