AV Access HDBaseT DisplayPort KVM Extender, Zero Latency, 4k@30Hz/1080P@120Hz, DP 1.2 PoE Extender, 2 USB 2.0 Ports for Keyboard and Mouse, EDID, Over Single Cat5e/6/6a/7 Up to 330ft (4KEX100-DP-KVM)

Very happy with this. I already own an AVAccess KVM for my main PC, so when I decided to start using a second mini PC (held in my network closet) for streaming my media library onto my living room TV, this seemed like a great option. Works great right out of the package. Set up was easy and I was able to start using right away. Everything was packaged carefully and everything needed was included. The only thing I had to provide of my own were two HDMI cables and an ethernet cable. Latency is very low and image quality is almost identical to a direct connection. I was initially concerned about issue with PoE as some other reviews reported it, but I had no issue. But I am using a brand new cat5e cable I had stashed, so your hardware may affect this. I plugged this into an AV receiver in order to run audio and video to my tv and still no noticeable difference from a direct connection. Movies and TV shows look and sound great. I set this up to test kind of hastily, but the low profile of both the receiver and transmitter will make it very easy to set up inconspicuously and out of the way of all my other devices. I may even mount it behind the TV. I am very happy with the performance so far.

I bought the this extender because I needed to place my PC in a different room and still have full control from my desk. Plugged it in with a single Cat6 cable and it delivered: I’m getting smooth 4K with zero noticeable latency, and all my USB 2.0 devices (keyboard, mouse, webcam) work perfectly at 50 m away.

Not often to I grant 4 stars. But the only problems I had with this thing is what is the lack of knowledge base thats publicly available to it. I am in IT, this is what I do. To me, a tech savvy guy... This thing was a pain in the ass. So heres the good and the bad: The good: Easy to setup Works when finished 0 Latency The bad: Lack of publicly available knowledge base regarding this product for troubleshooting USB functionality does not cover usb 3.0, I think it's at 1.0 but I could be mistaken since the last time I checked the specs. I spent hours on the phone with their support trying to get this to work. We eventually discovered that there is only 1 known type of display to HDMI cable that works with this system. which is the UGREEN Display to HDMI cable. The product works! But make sure that you have every bit of detail about what you are plugging into your machine before making this purchase. It does not support usb 3.0, so some of your accessories might not work. Very specific cables are needed under different circumstances.

Another edit: Soon after I posted the edit for some reason there was another post that said it worked perfectly for them and gave it a 5 star review. Which I find extremely suspicious. The reason being that there was another post that gave it a 1 star(its gone now) and not soon after that there was someone that said that it worked great out of the box. Now they did it to me. So yeah don't trust them or buy this especially with them manipulating the rating of their product. I could be wrong but I really doubt it with a product like this. Waste of 200-300$. I need to keep using it but I will have to look into a replacement option soon. Also it keeps messing up on me and it just keeps getting worse even just scrolling on the internet is messing with it. I wish I could just return it but they took a literal month to ship it to me(the whole return window). If I do get a refund or replacement I will update this post saying so but I really doubt I will get either. I'm deleting my original post. I don't want to give any credit where it is not earned. Edit: They were great when they worked. They now frequently flash weird lines like the graphics card is messing up(its not). I am also having a problem where it keeps going to a black screen every few minuets. It happens when I am gaming or even just watching a video it just flashes to a black screen for a few seconds then goes back the content then a few minuets later it will do it again. At first I thought it was the heat messing with something so I bought a fan for each extender part but that did not fix it. I will have to look into other aspects to figure out if its something that is happening on my end but I'm pretty sure its not. I am afraid when I really need them they will just black screen. Like when I am taking an exam for school or playing games(I died a lot of times because of it already). I am going to have to look into another solution. I would rather take reliability over looks when it comes to things like this. I thought this was reliable and cheap but I guess I was wrong. Its only cheap.

pricier than the alternatives, but you get what you pay for -- fantastic KVM that is much more stable and well-built compared to previous cheaper ones that i have tried. i chose this one because the previous one i tried had very limited USB support -- the drivers for the USB ports were for mice and keyboards // HID devices *only*, so no USB bluetooth dongle support like i needed -- and this one doesn't have that issue. i don't have hard numbers or measurements, but the latency is basically imperceptible for gaming. i played through jedi survivor and just finished bloodborne at 1080p + 120hz on my samsung QN90D TV, and it has worked flawlessly. so i really have no complaints at all, this is absolutely worth the money! i would recommend it to anyone who wants to use their computer for PC gaming on a TV in a separate room like i did minor things to watch out for (but which are not issues with the KVM itself!) -- make sure to get this newer version with HDMI 2.0 support, and use HDMI 2.0+ cables if you want to use higher refresh rates (120hz) or resolutions (4k, although i typically use 1080p). also, just something to keep in mind -- i had to dig around the website to confirm it, but this version does not support HDR this is a fantastic KVM that has worked perfectly for my needs, and i've had no issues with it at all. if they release an updated version with HDMI 2.1 support, i will almost certainly upgrade to it. highly recommend it!

Amazing product. I can send a 4K 60hz signal from my gaming computer 50ft away to my Sony 4K TV perfectly. There is no input or streaming lag, the USB 2.0 extension lets me connect a 2.4ghz gaming controller and a separate mini keyboard/mouse. The HDMI also passes all audio formats perfectly, I've tested compressed and uncompressed Atmos+TrueHD and no issues at all with any surround format. Yes it is pricey compared to cheaper ones, but I've tried a no-name and OREI and the picture quality of this AV Access extender is like I've got my computer directly plugged into my TV. The others the compression is very noticeable and text is pixelated. Also, the other extenders with USB it may only pass keyboard and mouse signals whereas this one has no problem with webcams or controllers. Also good service, my extender came with a faulty USB cable and they refunded me a small amount to buy a new one.

Unit has been used to watch maybe 30 movies in the past year. Today it quit on me. PoE is not working, can plug in either transmitter or receiver in with 18v and they turn on fine, but will not power other unit over PoE. Have changed out cat6 multiple times. What a waste of $270 at the time, I see the price has gone way up. Not worth it at all.
