AV Access 120M/390ft 4K KVM Extender over TCP/IP Ethernet, 120Hz High Fresh Rate, 16 Sets DIP Switch, 3 Ports USB 2.0, 4K@30Hz 1080P@120Hz over Single Cat5e/6 Cable, Zero Latency

I was looking for a way that I could have the same display from my PC HDMI go to my main monitor in my game room to the TV in my bedroom! I have this device hooked up to a HDMI splitter and then a CAT 6 cable running through the loft space into the bedroom wall and out behind the TV. I have a wireless mouse and keyboard and have the keyboard 2.4Ghz receiver plugged into the receiving end of this device since I use a wired keyboard at my desk and the wireless mouse is plugged into my pc and has very good range. The value for money is impeccable! The quality is excellent and it’s very easy to install, although to get it looking tidy and neat (for instance having the cable run through the ceiling into the loft and through the wall) it can get tricky if you have never done anything like that before! It’s the perfect solution though and works flawlessly! I am getting high fps (around 200 @1080p) which is plenty for me when I’m on a tv anyway and basically zero latency which is perfect for playing WoW in bed.

I work at an audio post production facility and needed a solution to run some high res displays with no compromise on sync. These boxes have been perfect. I've currently got about 4 pairs running in different rooms some at 2560x1440 and others at 1080p. All have been extremely reliable with no issues at all. No drop offs, no sync issues. USB is solid as well. I'd highly recommend these despite there being slightly cheaper products. These are perfect.

I don't usually leave reviews, but decided to for this product because it's a minefield knowing which KVMs are suitable for low latency applications. This one is excellent, as long as you have a dedicated run of Cat6 cable, isolated from the rest of your network. I use it to access my desktop at the other side of the house from my TV in the living room. This includes streaming, gaming and web browsing. It works well with wireless periperals (xbox controller, mouse, keyboard) and is very responsive. The PC can be woken from sleep by tapping a key on the keyboard in the living room. 1080p @ 60htz works well. I've used 4k @ 30htz too and it's good. The distance between the PC and the TV is about 30m and I'm getting no percievable lag - gaming feels exactly like it does on a monitor plugged directly into the PC (I'm not a competitive gamer though). Have found it to be very reliable - if it doesn't work it's usually been an issue with the PC being shut down or windows not liking different scren resolutions on monitor vs TV. Highly recommend.

when connecting the devices over one single switch works fine but doesn't work over a network with multiple switch.

Bought this after having issues with a different HDMI USB Ethernet KVM, so far it's been working very well. The image is clean and the response time seems great, can't even tell the difference to having my PC directly connected. I use it with a racing simulator setup, which I have connected to my computer outputting 1080p/120hz. I did have to disable HDMI Deep Colour on my TV to get an image, after contacting support they told me it's because their unit doesn't support 4K/60hz only 30hz, which is stated in this description. I use 2 of the USB's for my steering wheel and pedals with a powered USB hub in the 3rd port, which I connect a wireless Keyboard and a USB wireless headset. I haven't experienced any issues after hours of use. My only issue with the device is that after using it and turning off the receiver end my PC still stays connected to the HDMI output so I have to unplug the HDMI to my graphics card for it to go back to the Display port which my monitor uses. Not a big deal though.

I needed a kvm to control a remote pc that runs our home automation. I decided to run a dedicated network cable between the tx and rx units. The result is amazing. There is zero lag from my key presses to what appears on my monitor, mouse control is equally lagless. It worked straight out of the box, no configuration needed. I would recommend running a network cable between the two units rather than using your lan for the best result.

Good, simple device to use. Quality could be better

This is a very well made extender as you would expect from the price tag (£162), which I think it is a decent price but still an expensive piece of kit. The extender comes with a transmitter and a receiver, if you are doing a single extension then all you need to do is to plug in the HDMI cable and the USB cable from your computer to the transmitter, connect the transmitter and the receiver using a fast ethernet cable (CAT5 or above), then you got your USB ports on the receiver where you can plug your keyboard, mouse or whatever you want to control your computer. Both the transmitter and the receiver come with individual power adaptor that has 3pin UK plug or Europe plug converters. This extender allows me to take one ethernet cable up to my bedroom TV and I have full control of my PC downstairs on my TV. As if I was having a PC next to me but using a different my TV as monitor which is very handy to watch movies and even do a bit of gaming on the bed. In terms of performance, I have not noticed any latency. At 4K quality this can only run 30fps which is not so smooth but most games or videos I watch online do not need the full frame rate so it is enough for me. I don't have a HDMI splitter, therefore each time I go back to my PC downstairs I will need to unplug the HDMI cable and plug it back into the monitor downstairs, which is a bit of a pain. It could do with a HDMI out in the transmitter too so that I dont have to source my own splitter. Overall, this is a very simple solution to 'remotely' control your computer. It has a dip switch so it can form part of the one-to-many or many-to-many connections. The size of this is a lot smaller than the earlier generations KVM extender. It is not cheap but definitely very useful if it suits your need.
