AV Access 4K HDMI Fiber KVM Extender Over IP, up to 550m/1800ft, Zero Latency, 3xUSB 2.0 Ports, Remote Keyboard Mouse USB Control Over Fiber Optic, Remote PC Control in Server Room (4KIP500F-KVM)

We have a pretty beefy gaming desktop that is unsightly and loud under load. It also doubles as a space heater. :) We normally keep it in the basement but sometimes we want to play in the living room on our 4K tv. Lugging the desktop up and down was a pain, plus we have a ups for it in the basement to protect it from power glitches.So I hesitantly got this figuring their would be video/audio latency or USB input latency. Much to my surprise it works great, no latency, with 4K@60fps and surround audio transmitted. We also have a USB based force feedback steering wheel for racing games which works awesome and we can plug in our Xbox USB wireless controller adapter and use those controllers in the living room. Very pleased with this device so far. I'm using a flat cat6 100' Ethernet cable to connect the two ends.

Absolutely plug and play. I ran an unshielded Category 6 cable just a little less than 100 meters in a huge warehouse from the IT room to the main offices. Plugged in the HDMI cable into my NVR which outputs 4K. I have over 45 four megapixel cameras in the NVR. Plugged in the HDMI on the other end and a wireless mouse. You only need power on one side. Now my customer can control the NVR right from the 4K TV in his office and look at the entire facility, zoom in, configure, etc. The display is amazingly crisp and clear. We used a wireless mouse on the receiving end and it also came up right away through the USB port. Great product. I looked at other products costing $700-$800 and read reviews and a lot of time they didn't work as advertised. Ryan at AV Access answered my questions right away by email and made me confident it would work and it did! I picked a winner.

My PC is now in the basement where it is nice and cool, and I will eventually put inside a dedicated conditioned/filtered cabinet. Monitor and wireless keyboard/mouse are upstairs. Everything works great with no lag. I won't say zero because i haven't measured it, but its so close to zero that I can't tell. It wakes up my PC when I jiggle the mouse. The 4 ports are nice so I can put in a usb stick and transfer files. Not as fast as the USB3 at the PC, but good enough for smaller files. The only downside that I've found is that when I have windows set to extended desktop, it can't figure out if one of the two monitors is disconnected. Usually if you have two monitors hooked up to a single windows machine, it can tell if one is unplugged and will automatically switch to a single display. With this device it always thinks the monitor is connected. So if you sometimes work on a local monitor and other times at the remote, you'll need to manually tell windows which monitor is your active desktop. You can leave it in extended mode, but you'll have windows open up on the other desktop and its a pain to drag a window into the active screen when you can't see it. Even with that little bug, I'm happy with the performance. I only have a 1080p monitor, so I can't comment on the 4k capability. I purchased this for an eventual 4k monitor for future proofing.

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 didminor 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 HDRthis 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!
