AV Access 4 in 1 Out HDMI Multi-Viewer Switch with 5 Display Modes, 4K/1080p HDMI Out, 3 Way Control, IR Extension Remote + RS232 Control + Button Switch, Plug and Play

Model 4KEX40 is an affordable alternative for any need of transmitting 4K like extending NVR. It does it up to 30 fps. The housing body is metal and it look like quality build. Their newer models allow for PoC (Power over Cable) eliminating one power supply from setup. I did not experience overheating from this unit.

happy with it have a projector but was running Bluetooth to speakers and had audio lag so decided to use all HDMI connection this worked perfectly no lag with sound quality is great. it a solid device

Bought a cheaper extender from a different manufacturer originally, but it idn't work with my devices connectedat 1080p. Picture was very grainy with my FireTV unless I set it to 720, and wouldn't even transmit the signal from my DirecTV receiver since DirecTV was set to auto negotiate the resolution. Only Max of 30 feet between receiver and transmitter. Good thing Amazon return policy is so good. Got this extender instead and it works flawlessly.

I just got my 4KEX40 from AV Access and it works perfectly! My first test was to hook it up against a PS4 with a 10 meter CAT6 to my Philips 4K Monitor and played some split screen Call of Duty WW2 in 1080p to see if there was any delay, but there was none, worked just as if the PS4 was plugged in directly to the Monitor. I even tested the 4K@30Hz against my Nvidia card on the computer and it also worked flawlessly. I am very satisfied. A part from that the power adapter actually support 110-240v which means that I can use it in both US and Europe.
