J-Tech Digital 4k 2X2 Video Wall Controller Multiviewer Seamless Matrix 4K@60Hz Input 4K30Hz Output HDCP 2.2 [JTECH-VWM04]

I actually bought the standard one first that is the upper two TVs and I purchased this 4K which is the lower TVs this machine is fantastic well worth the extra money would highly recommend it to anyone

The Amazon description of this device includes a few pictures. I used those to purchase this device. The pictures showing "Vertical" are exactly what I wanted to accomplish. Guess what! They lie. J-Tech support tells me there is no way to do this with this device. Don't buy! I have an email from them proving this if you don't believe me, ask them! Wasted my time.

Item stopped working in less than 3 months. Complete waste of money, very expensive paper weight.

Life saver for running HDMI across large rooms. Easily allowed me to reach my TV's over 75' away in a large room with no loss of signal or picture. Easy to install on each end. Hardest part was running the Cat 6 cable really.

I bought the HDMI Extender to run a 4K signal from my media server to a wall-mounted TV about 100 feet away, it’s been flawless. I’ve tried other extenders before and always ran into signal drops or weird compatibility issues, but this one just works. Plugged it in, powered it up, and boom—clean 4K video with zero lag. 📺 Crisp 4K@30Hz Over Long Distance I’m running 4K@30Hz over CAT6 cable, and the picture is crystal clear. No flickering, no artifacts, no weird handshake problems. It’s rated for up to 132 ft at 4K and 230 ft at 1080p, and I believe it. I tested both resolutions and they held up great. Perfect for home theater setups or even office displays. 🔁 HDMI Loop Out = Local Monitoring Made Easy The loop out feature on the transmitter is super handy. I’ve got a local monitor hooked up so I can see what’s playing without walking to the other room. It’s great for troubleshooting or just keeping tabs on what’s live. 🔊 Audio Extraction Works Like a Charm The 3.5mm audio out on the receiver is a nice touch. I hooked it up to a small soundbar and it pulls stereo audio cleanly from the HDMI signal. Just make sure your source is set to stereo output—took me a sec to figure that out, but once I did, it worked perfect. 🔌 Power Over Cable (PoC) = Less Clutter Only one power adapter needed thanks to PoC. I plugged the adapter into the transmitter and the receiver powered up automatically. No need to run extra power lines or find another outlet—huge win for clean installs. 🛠️ Setup Was Stupid Simple Literally plug-and-play. No drivers, no firmware updates, no weird settings. Just connect HDMI, Ethernet, and power, and you’re good to go. Took me maybe 10 minutes total, and most of that was just routing the cable. 📦 Build Quality and Support Feels solid—metal casing, good weight, doesn’t feel cheap. Comes with IR cables too if you wanna control your source remotely. Plus, J-Tech offers lifetime tech support, which is nice to have even if you don’t need it. If you need to extend HDMI over Ethernet and want something reliable, this is it. Clean video, solid audio, easy setup, and no extra power mess. I’ve already recomended it to a buddy doing a conference room install. Would definetly recomend to anyone looking for a dependable HDMI extender that doesn’t break the bank or your patience.
