Use dedicated ethernet cables. - Used this to remote the 4K monitor on my Lorex NVR with 4K HDMI output. Initially had issues trying to get the boxes to connect to each other when I ran them through a PoE switch on their own VLAN. After trying a few times via the switch, I directly connected them to each other with a single CAT6 cable and using the supplied power adapters and they quickly linked up. I then moved them back to the PoE switch on an isolated VLAN and they were able to link up just fine. Has been reliable for the last few weeks with no hiccups. PRO TIP- You really should put these on their own dedicated ethernet cables to each box. Do not share the cable bandwidth with other computers, etc. Why? Because these boxes are using about 800 Mbps of bandwidth at 4K 30FPS. 1080p doesn't drop the bandwidth much (uses 650-700 Mbps). -----UPDATE 10/20/2022----- This is a followup from my original review on 1/8/2021. Happy to report this 4K HDMI extender is still going with no issues so far. Both sender and receiver are connected to a PoE gigabit switch (wall warts not being used). Used in 4K30 mode with a mouse for a camera NVR. Review: Good concept but poor implimentation, documentation and high price for an extender with issues - I really regret purchasing this system and even more regret not fully testing before the return period was up. That part was my fault. My use case: I have two head3dless servers in a computer rack that I needed to have keyboard and video connectivity when changing bios settings, repairing OS, upgrades, etc. Having some experience with KVM extenders in general, I am a little leery of trying ones I have had no experience with but needed one over IP so decided to give this one a try. The POSITIVE: The receiver and sender did see each other quickly and connected without a problem. I am (was) using this KVM extender through a Cisco POE switch on a dedicated VLAN (with POE for power) which all worked fine as well. The NEGATIVE: As mentioned 99% of my need for this system is only to see the BIOS screen, POST info and Linux and DOS based boot (USB) drives to run diagnostics/ upgrades, etc. And this is where I have had a miserable experience. The first server I tried it on was a Ryzen based system (with a GeForce GT 710 1GB dedicated only to this video requirement) and running Proxmox. On this system, I could not get ANY intelligible video (just video noise) at any time- POST, BIOS, etc. The second system (also Ryzen with the same video card running Proxmox Backup OS) is almost as frustrating! The screen will NOT stop blinking on and off no matter what I try! I have rebooted many times, reset the extender many times, tried other configurations, in BIOS, DOS, Linux but still it keeps blinking. Sometimes it loses the keyboard but always keeps f-ing blinking so much it is hard to do anything, much less how crazy annoying it gets. And it doesn't help that the documentation is so ridiculously basic and so little detail that it is no help with troubleshooting any issues! I'm not sure how it works with a "standard" video signal but BEWARE if you are trying to use it like I am. ## Features - 4K@30HZ Extender: The 4k kvm usb extender extends 4K up to 328 feet (100 meters) over Cat5e Cat6 UTP cable.

Any suggestions? Lan is gigabit but there are two switches in the chain, and they are old.** A: Thank you for your question. First, you need to turn off the Engrgy efficient Ethernet (EEE) function of the switch. Second, you need to calculate the bandwidth of the entire link. The maximum network bandwidth of the KVM extender is 850Mbps. If it exceeds the range, it may affect the transmission. If you still can’t solve it, please contact the store customer service, thank you! **Q: Does it also support resolutions in between? Like 2560 x 1440 & 1920 x 1200?** A: I believe it does I have never tested that I know it supports 1080p and you can connect it in a poe switch and not have any issues connecting them together so if you don’t have a direct connection it will still find the transmitter as long as the dip switches are set right **Q: After 2.5 months this Extender failed. Do you have a warranty?** A: Yes, we promise a one-year warranty, you can contact the seller for details, thank you. **Q: i have one of the basicolor 4k hdmi kvm usb extender, kvm extender over ip over ethernet cat5e/ cat6. i need a manual for the 5631poe 4k** A: Hello, you can contact basicolor by email to get the manual. The extender is connected to the transmitter and receiver through CAT5 / CAT6 / cat7 network cable. The transmitter end is connected to the signal source with HDMI cable, and the receiver end is connected to the display with HDMI cable. Thank you. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It totally WORKS!

However IF you’re bouncing them through a networking switch. Make sure the switch can handle them. ## Frequently Bought Together - Basicolor 4K PoE HDMI KVM Extender Over IP, USB Ethernet Extender Over Cat5 Cat6 up to 328ft(100m), Plug & Play Lossless & Near Zero Latency, Support Point to Point & TX RX Team Connection - USB 3.0 KVM Switch HDMI 4 Port Support 4K@60Hz 2K@120Hz Simulation EDID,MLEEDA HDMI USB Switch for 4 Computers Share 1 Monitor and 4 USB 3.0 Port,with Desktop Controller and KVM Cables - BENFEI 4K DisplayPort to HDMI Adapter, Uni-Directional DP 1.2 Computer to HDMI 1.4 Screen Gold-Plated DP Display Port to HDMI Adapter (Male to Female) Compatible with Lenovo Dell HP and Other Passive --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/181738743-basicolor-4k-poe-hdmi-kvm-extender-over-ip-usb-ethernet](https://www.desertcart.de/products/181738743-basicolor-4k-poe-hdmi-kvm-extender-over-ip-usb-ethernet) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-04-24*
