TESmart 4x4 Multi-viewer HDMI Matrix 4K Video Switcher 4K@30hz, HDCP, EDID, 4 in 4 Out Updated 4x4 HDMI Matrix Switcher Control by IR Remote, RS232

At our old house we built a bar in our back yard, and over the years our amazing neighbors gifted us items to make it a legit watering hole. Among those gifts were TVs to hang on the wall, you know, like bars have. I know it seems extravagant to gift a TV to your neighbor, but these were older ones that they'd replaced with newer technology. Think a 720p replaced by a larger 4k TV, and they weren't sure what to do with the old one.Anyway, we recently moved to a new house which does not have a great backyard space for a bar. It does have a small upstairs game room though. I didn't want all the TVs to just sit in the attic so I came up with a plan to hang five of them on the game room wall. I do have three kids living at home, so they could each have their own gaming TV and the two larger ones could be for the... audience? I don't know. I had to make up some kind of justification to put five TVs on a wall.Long story short, I mounted all five TVs to the wall. I bought myself a new xbox one x and gave my son my old xbox one, then bought two xbox one s on a Christmas sale for my other two kids. I pulled an old original xbox out of storage and even an original Wii. I also had two Amazon Fire sticks that were used on the bar TVs. The next question was how to make this all work.I could, of course, just wire everyone's xbox to their respective TV and be done with it. If I wanted to play a classic xbox or wii game, I'd just swap out the cables to one of the TVs. The xbox can connect to youtube, netflix, etc. so there's really no need for a fire stick on those TVs. The sticks can go on the big TVs.But where is the coolness factor in that?Thus began my research to find a way to take those multiple inputs and broadcast them to any or all of the TVs on that wall. It didn't take long since there is an entire industry built around doing that very thing. I delved into the world of HDMI matrix switchers and at first was disappointed because they were all so expensive. I certainly like paying lots of money for things I don't really need, but there is a limit despite what my wife thinks.Then I came across the TESmart switcher. Half the cost of the nearest comparable 8x8 switch, it seemed like the perfect solution. But being half the cost sets off alarm bells because there has to be some horrible catch, right? I read through many of the reviews and saw people talking about loud beeps, TVs cutting out when switching sources, poor instructions, and what-not. I decided that for half price I was willing to live with a few inconveniences, especially since the switcher was intended to eliminate some even more inconvenient inconveniences that didn't really need to be eliminated at all to be perfectly honest.I've had the switcher installed for a couple weeks now and really the most difficult thing about it is remembering what device is connected to what port. I am going to get a labelmaker or something so it's easy to identify sources and outputs. Otherwise the switcher does exactly what I want and even a little bit more.Addressing the complaints:Yes, the beep associated with pressing the buttons is insanely loud. You can hear it throughout the entire house. The good thing is that you can turn off the beeps by using the associated software. I haven't done that yet but that's on my to-do list.Video cutouts do happen. Not all the time, strangely enough. It can be annoying when someone is in the middle of playing a video game and their screen blanks for about one second, but it's really not that big of a deal for anything else. It beats completely rewiring things.Switcher don't switch: Sometimes the switcher just doesn't want to do its job. You press an output, a source, and nothing changes. You can try changing the output/source combo, but occasionally the switcher just doesn't want to obey. There is a very simple solution to this - power cycle the switch. As you can imagine this isn't ideal if someone is in the middle of a game or whatever. I'm not sure if there's a fix for this but I would love to get it.And now for the awesomeness:MAJOR coolness factor. I had a NYE party at my house and everyone was just blown away by the switch. Showing the same video on all TVs was the most popular demonstration. I'd blaze through the buttons and put different inputs on other TVs and people were agape. Which is funny because they see this technology at practically every sports bar they've ever been to. I guess you don't see it in houses all that much.Works with a soundbar! I put an older soundbar as one of the outputs and it works beautifully. You just pick whichever output you want to hear the sound from and assign it to the soundbar and BAM, you have audio. For our setup this is great as all three kids have headsets for their xbox. They can listen to their own audio and if one of them has guests over they can put their xbox to the soundbar so everyone else can listen in. Or, all three xbox could be in play and the rest of the people can watch something on one of the fire sticks.The future: I bought a raspberry pi zero w and an RS232 connector and my plan is to create an Alexa skill to do the switching with voice commands. I'm working on it now and will update my review when I have it up and running.Overall one of the most fun and cool technology purchases I've made in recent times!

Works better than advertised. I've had success using multiple 100' hdmi cables as well. Awesome for the price. No issues after 4+ weeks of use

Ive had this switch for a couple weeks to a month so take this as preliminary observations if you may.First thing i have to say is this is the third switch ive bought since january. Im starting to come to terms with the fact that none of them are perfect. For this one theres a few issues but none of them are deal breakers for me but may be for you.Lets start with the remote. Its, in a word, rubbish. Its a small credit card style remote with only a few tiny buttons on it. Mine did not come with batteries, which it says in the ad it does not so i knew that going in. It did however take standard AAA batteries which was nice. It has no power button on it, and 2 of the buttons do nothing at all(even says it in the manual.)Now lets talk about the auto-switch. I find it best not to use it. Its super sensetive so if theres a computer hooked up but its asleep, itll switch to it as soon as it wakes up again whether u want it to or not. Even over powering an always on device like my roku. This is use case though and your mileage may vary. The device comes default to auto-switch off which it again notes in the manual. Its also nice the input device doesnt have to be on before you can switch to it.But heres my biggest problem with this thing. While it switches fast, when it switches it only comes back at 1080p. Its like they sacrafice video quality for fast switching. The way i found around this is when it switches, turn the out device(tv in my case) off then on again and itll will get you 4k at 60hz and hdcp 2.2. it doesnt take 5 minutes of playing with it like one switch i tried, and doesnt cause any funky glitches with other equipment like another so its still usable.All in all apart from some faults, it works. Im still on a quest to find the best 4k hdmi switch but i can deal with this one for awhile until i can buy another.

I was looking for a way to share two monitors between two laptops; one personal and one 'work". This works great and took only about 5 minutes to set everything up. Only thing I would add to a wish list is USB so it could switch wireless KB/Mouse, as is you'll need an external solution; I just used two separate KB/Mouse setups- one for each laptop.

I’ve had the product for a few months and I have not been able to get it to work. I would encourage anyone not to waste their time or money. The instructions were not helpful at all. Don’t let the fancy video promotions fool you. BUYERS BEWARE, if you’re looking to create a video wall this product is not the one. If I could have rated it a zero I would have.

Works great. I use it to connect to my cable set top box, VHS, Blueray/DVD, and laptop devices, with one connection/feed to the TV. It’s easy to switch between devices using the remote.

Picture quality is great. I wasn’t ready to condemn my Harmon kardon avr the hdmi port was failing but the sound quality was awesome so I opted for this product. Very happy with the purchase. Have had it 2 weeks now. Will update review if anything changes

The device does its job - no complains here. My only issue with this and other TESmart units, that are currently sitting on my desk for testing, is that one remote control operates all of them. I mean come on! You operate one unit and it kills setup on another unit, even if they are completely different models. Specifically observed on TESmart 8x8 matrix and this TESmart 4x4 matrix. You may say that at least the remote controls are interchangeable, so if you lose one, the other will save the day. Besides this issue I'm happy with both TESmart devices. They don't require a reboot every other day and they work as described. Very good deal!

The equipment is as per specifications. However the switching time for one output to other is more than 4 secs.
