4x4 Matrix Video Wall

Fantastic device Little large but works perfectly

I got this device for use with my home entertainment system and it's great. I use it every day. The price was right, and the build quality is nice. There's only one problem (see below). So far, I have two screen connected to it, and 4 HDMI devices. It seems the product was designed for bars, restaurants, or other commercial applications where multiple screens (up to 4) need to be connected to various sources (up to 4). You could expand to any number of screens with an appropriate HDMI splitter gadget. I can't say I've tested every possible configuration, but I've had no problems with my own combination of gear. The transitions between sources are clean. I've used my collection of various HDMI cables with no problems. The video quality is great. There is no lag or glitching introduced. The remote control is interesting because you can program various macros for frequently used command sequences into it. I've only scratched the surface with that so far. Another feature I haven't been able to explore the functions available through the 9 pin RS232 connector. No, that is NOT a VGA connector, although it looks like one. This opens up the possibility of computer control of the device which is an exciting concept, a pleasant surprise with the low cost of the unit. The unit comes with a 34 page instruction manual which is pretty good, and provides a full description of the controls available with the RS232 serial interface. It also provides trouble shooting guide including suggestions should you have an oscilloscope (I do). * Good All and all, a very good product. And as I said above, I use it every day. * Bad The bezel for the display on the front is made of very thin and flimsy, scratch-able, not cleanable, plastic. Given my propensity for scratching and getting fingerprints on such areas of devices, I may open the unit and glue in place a more solid material. You may very well not feel such a modification is needed * Very Bad It's a good thing this product has a front panel power switch. I am a ham radio operator, and I quickly discovered that the unit puts out a LOT of noise in the VHF spectrum. It completely wipes out reception on the 2-meter band. It might interfere with devices that you have as well. What I do is turn the unit off when I plan to use the VHF band for QSOs. I gave this unit four stars, mostly due to the interference. It may be possible to reduce the VHF noise by using only cables that have ferrite beads on them, or put on ferrite beads yourself. I haven't tried that, since turning off the unit solves the problem just fine for me.

Picked this up to untangle the mess of consoles and monitors in my office. Plugged in 4 sources and 4 screens and the matrix sorted every route without fuss. The little LCD tells you whats feeding what so no guessing. Button clicks feel solid and the remote actually works from across the room. 4K at 30 Hz looks fine for gaming on my retro rigs and the box can drop the signal to 1080p for my older projector. No joke, I was switching from my PC to the work laptop in under 2 seconds. Friends come over and we flip inputs mid match, zero complaints. The metal shell feels sturdy yet stays cool after a long movie night. Setup took maybe 5 min, the included RS232 cable went straight to my home lab gear. Power off memory holds the last layout so i dont have to set things up every morning, small win that saves time. At 80 bucks it beats running new HDMI lines through the wall. Only gripe is the blue status lights are a tad bright so I taped them, not a deal breaker though.

Confusing. Would not hook up. Entire video wall and switch would not connect.

It’s a pretty good matrix for the value. It offers a clear quad video output which is what I needed and the low frequency isn’t an issue for such a purpose. Installation is easy and even without a web gui management is simple enough to figure out. Overall, not bad at all.

This thing is too cool. I know you can use it for marketing and what not -- but I've got it on my workbench so i can feed any input (computer, raspberry pi, laptop, extra) to any output (screen 1, screen 2, capture card, unused) super, super easily. Fantastic addition to the old workbench! It's about 1/2 of 1U in size and comes with a remote.

This is a very nice HDMI switchbox. Very heavy duty construction. All metal case. The buttons all feel sturdy. They actuate with a positive click and illuminate to show which ones are active. The display is nice and bright and shows which inputs / outputs are active, as well. I'm using this in my home theater. I have each of the inputs connected to my various gear: Bluray player, Laserdisc player, TV box, and Gaming systems. The outputs go to my flatscreen and my projector. This setup allows me to utilize a single input on the TV and just use the switchbox to control what goes to it. When I want the "full effect" I just switch the output to my projector and pull down the screen. I noticed zero lag or sound syncing issues. The inclusion of a remote control was a nice touch. For as advanced as this piece of gear is, it's very simple to hook up and use. I appreciate the compact form factor. It was easy to integrate into my entertainment center. This would also be very beneficial in an office or presentation scenereo where multiple inputs / outputs would be shown to a group. Overall, I'm very pleased. This is basically broadcast grade quality in a compact package at a consumer level price.

This is easy to use for setting up a video wall, but from my experience, using the same TV/monitors for each output is best. If I used this with a mixed monitor type that didn't support the same output formats. This only seemed to matter if I used a very new display with a very old one or tried to mix in a 720P display with 1080P displays. Quality is good and video was good when used as a video wall or independent outputs. A GUI would have been nice to have, but wasn't too hard without one.
