AV Access 4K HDMI USB KVM Extender TCP/IP Over Single Cat5e/6/6a/7 up to 120M(390ft), 1080P@120Hz, Plug & Play, Keyboard & Mouse Over Network, Zero Latency, 3 Ports USB Hub, DIP up to 16 Sets

I've been using this extender for about a week, and it’s been rock solid so far. I'm running it at 1080P@120Hz over about 100m of CAT6 cable to my gaming setup, and the image quality is crystal clear with zero lag. The 3 USB ports on the receiver side are super handy — I have my mouse, keyboard, and a USB headset plugged in, and they all respond instantly. Setting it up was straightforward — no drivers, just plug and play. I like that the power connectors lock in place, so nothing gets accidentally unplugged. Also tested it with my PS5 and Xbox, and both worked flawlessly. If you need to control your PC or console remotely with smooth, high refresh video and stable USB connections, this is a solid choice.

I've been having a medical issue/pain, which is preventing me from sitting in my office chair for more than a few minutes at a time. I'm a lifelong gamer, so not only was I having to work on my iPad, but I couldn't play any PC games. I got some super long cables and ran them across the house to connect my PC to the living room TV, but I don't like clutter and it started driving me nuts immediately. My husband fabricated an amazing monitor stand to go beside the couch, and I bought these delightful things (AV Access 4K HDMI USB KVM Extender). I hooked them up and they worked immediately! I have zero lag, and have played several games, including World of Warcraft and Aloft on Steam. Even my USB headset works for Zoom calls. There have been maybe two instances where they didn't work when I started the computer, but disconnecting the Ethernet cable and reconnecting it did the trick. It has not dropped while I'm actively using it. The entire ~40' run (from the first KVM to the wall jack, from the inside of the female-female office jack to the inside of the living room jack, from the living room jack to the second KVM) is CAT6 (https://www.amazon.com/dp/B07J6NJDRV).

Tested with multiple known-good cables (that are short and well below manufacturer's required lengths) and accessories that work perfectly with other devices, but not this KVM extender. To an HDMI monitor for testing: Blank black video with partial image flickering once every second for about 10ms. This was with both TX and RX independently powered with their AC transformers, multiple known-good short HDMI cables that each function fine when directly connected from PC to Monitor/TV, with multiple known-good CAT5e and CAT6 ethernet cables that also function elsewhere. To a receiver port that works with local devices and another KVM extender I tested today: Blank black video. Display is not recognized at all on the PC (unlike the monitor). USB: Some wired devices function (several wired mice), but no wireless USB dongles I tried worked, including a wireless mouse that works when directly connected to multiple computers, and a wireless Xbox controller adapter dongle that works when directly connected to my PC and a SteamLink. The USB ports are reportedly 2.0, but recommend 0.5A or less power draw; I was unable to confirm the exact power draw of my Razer wireless mouse dongle or the Xbox adapter, but I seriously doubt they're drawing more than 0.5A. Returning and trying another product.

Initially I wanted to run this through a switch, but for some reason can't get a signal even though I set the dip switch to channel 1 on both ends. I made sure to power cycle both end points, but still no luck. Luckily, I had extra ports on the wall that can run directly, so I can confirm it works. Mouse/Keyboard/8bit Duo Ultimate 2 Controller AND display works. No latency noticed. Even while gaming. Resolution configuration could be better. I could only do 4K @ 30 Hz, 2K @ 30 Hz, 1080p @ (30 Hz, 60 Hz, 120 Hz). There is no in between. I was hoping to be able to do 2K @ 60Hz, but nope. It always goes down to 1080p when trying that resolution and speed. I ended up settling for 1080p @ 120Hz.

Works really well and straight forward setup. I'm using it to connect my racing sim to my PC from across the house through cat6a. Only problem is that it uses a lot of bandwidth, 1 Gigabit switch is just barely enough for 1080p 60hz and my USB devices. Doing anything else that requires the network on the same line causes the screen to flicker (such as discord screensharing). I'd imagine i'd need to upgrade my switches to 2.5 Gigabit to resolve this issue, but it would have been nice for the merchant to mention this, or perhaps better optimization of the KVM Extender. A direct connection of the extenders would also likely eliminate this issue, but that isn't possible with my network.
