AV Access HDMI KVM Extender 50m/164ft, 4K@60Hz 4:4:4, 1080P@240Hz & 2K@144Hz, 4 USB 2.0 Ports, Low Latency, PoC, EDID, for Gaming PC, Office & CCTV (4KEX50-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.

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!

it works with a small monitor at 1920x1080p. I bought it for a sim rig in lower floor 25 ft away. A 34 inch widescreen monitor @4k is too much for it. Documentation could mention monitor limitations but does not. Giving 2 stars because i have a very expensive usb extender that will not support my monitor.

This is definitely not lossless or zero latency. There is noticeable compression, a 1440p signal looks more like 1080p. Latency is also there, maybe 20-30ms at 60Hz. I used this with a Cat 7 cable. It works but for my purposes for gaming I'm looking more at active HDMI and USB repeaters and cables.

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.

I bought this to connect my PC to a TV in another room, and it’s been great so far. The signal stays stable. The extender is well made, match the product description.

I'm fairly new to HDMI extenders but following a failed unit I previously bought I saw this and given the positive reviews decided to order when I had the chance. First off this one was so much better packaged and looked more premium. I really hate poor packaging as it's often a sign of the general quality of whats inside! The unit itself feels really well made and is heavier than I expected though it's compact and easily hidden from view. There's not a huge amount to this but it does an excellent job where it needs to. I'm not a gamer and my needs are more content viewing related but the various refresh rates are a huge benefit whatever usage case you have. Obviously the KVM part is the main usp here. In terms of audio output, this will support stereo but if you're looking for surround sound this won't provide what you need. For my needs this extender has been excellent. It's not cheap and there are more affordable options out there but this is pretty flawless in my opinion.

This is an excellent HDMI/USB extender. It extends an HDMI video/audio signal over a network cable (Cat5e/6/6a/7), supporting 4k@60 Hz with chroma 4:4:4, as well USB for a keyboard, mouse and other USB accessories. In my testing with a Mac and a 25' (7.6 m) Cat8 cable, the audio and video worked perfectly in 4k@60 Hz, without any latency or signal degradation. The output was indistinguishable from a direct connection. The transmitter and receiver are made of metal (aluminium, I think), with rubber feet to prevent sliding. The build quality looks very high. The package also includes brackets and screws for fixing the transmitter and receiver to desks, walls, etc. For power, there’s an AC adapter, together with AC cables for the US, UK and EU. I left the UK and EU cables out of the photo. For connectivity to the host device, there’s a USB-B to USB-A cable, which uses the USB-B port on the transmitter. There’s also an instruction booklet, which I also left out of the photo. To set up the extender, the power should be connected to the receiver. The transmitter is powered using power-over-cable (PoC), which is similar to power-over-Ethernet (PoE) and allows the receiver to supply power to the transmitter over the network cable. Next, the USB-B to USB-A cable is attached from the transmitter to the host device. Finally, HDMI cables are attached at each end. Audio is transmitted over the HDMI output, but for those using separate audio systems, e.g., because the monitor lacks audio support, there’s also a separate connection on the receiver for audio. I’ve used a number of HDMI and HDMI/USB over network-cable extenders, and this one is the first I’ve seen that supports 4k@60 Hz. It’s also the best in quality and performance. The price is relatively high, but the performance and quality are well worth it. Overall, I can highly recommend this product.
