CKLau 4Kx2K@30Hz 4 Port Multi-View HDMI KVM Switch with Cables, Audio and USB 2.0 Hub - Quad Screen Divide/Sync/Single-View Switching Up to 7 Modes

This switch is versatile and just functions the way it is supposed to. Great tech, will continue buying as my pc setup continues to become more complex.

It certainly does the job for what it is created to do. It works very well with my laptop and my PC, both with Windows.

The second video output on KVM is defective. It doesn't capture the video signal. It just give out static noises.

Awesome device, agree with other reviews.Only problem is the EDID button on the front, which the manual says toggles between 4K and 1080p modes, doesn't seem to work for me. The 1080p mode is not recognized by my monitor even though its my monitor's native resolution. The 4K mode works fine but since I have to run it in 4K mode, all of my text-based devices (Linux consoles) have the text too small to read.I might mitigate this by putting EDID emulators in all 4 input lines to limit their resolutions to 1080p but it doesn't feel like I should have to do this.

This is the best KVM Switcher that I've ever encountered!Pretty simple to install and a wonderful quality.A+

Good unit, BUT.....The included instructions reveal the fact that all computers connected to this device require two video outputs, one vga and another hdmi...This was not indicated in the description on the site. Also, When using the ports for the Number 4 position, these cables are so close to the output cables the connectors need to be trimmed in order for them to plug in next to each other. I was hoping this would combine EITHER VGA OR HDMI....Not the case.

If you have uo to four sources and want to flexibly display them on two monitors, you will have a hard time finding a more capable device than the CKLau 4 Port Multi-View KVM Switch.It's a complete KVM switch. It doesn't just switch video signals, it switches your USB devices as well. It's compliant with USB 3.0, and is not constrained to just a keyboard and mouse. You can connect a compliant hub and switch a variety of devices, including printers, scanners, and external drives.The flexibility is really apparent if you want to combine dual video output from up to two computers, instead of four discrete computer systems.With four computers connected, you can use the switch in a number of different ways.* One main display for any selected computer, 4 way split screen on the second monitor so you can see all outputs at one time.* Four way display with one primary display on the left side with three stacked smaller displays showing the other computer outputs.* Picture in picture* Split screen* Two computers on two monitorsIf you're connecting two computers each with two video outputs each, there are yet more options.* Extended mode, where one monitor shows both displays side by side from each computer, one computer over the other.* Duplicated mode, where one output displays over the other from the same computer.* Splicing mode, with side by side views from the same computer.And virtually every combination of these modes is possible. With all these complications, it could be confusing to operate, but a simple wired remote control panel is included and makes operation very clear. You controi which inputs go to which monitors, and what effect to apply to each monitor.There is so much flexibility here, and there are lots of ways to display your four HDMI devices. The only constraint is that they need to be at standard HDMI or 4K. With support for 4K and USB 3.0, this is the most capable KVM I've seen.

It would seem that the most important thing about getting this to work properly is the turn-on order. This was on, like, page 1 of the instructions. The rest was filled with a...frankly dizzying array of different input configurations this is capable of, from multi-graphics card computers to game consoles with an equally dizzying array of different display configurations. I've used quite a few KVMs. Some nice ones, too. I don't think I've ever seen one that does as many different things as this can do.And they don't skimp on the accessories, either. There is probably $50 or MORE worth of USB and HDMI cables in the box. I've seen KVMs that come with little more than a power cable.There is one little...oddity...and that's the presence of a wired remote. Yep, you read that right. As in, connected with an actual wire. This is like, some serious 1950's nostalgia built into an otherwise ultra-modern piece of gear.I don't know how many of you are up on your "TV remote control history", but the first ever TV remote control was invented by Zenith in 1950. It was called, humorously, the "Lazy Bone". And you guessed it, it used a rather bulky cable to connect the remote to the TV, and could raise and lower the volume as well as change the channel. High tech! In 1950 anyway...the "clicker" wireless remote didn't come until some years later.So, this has a wired remote. It's...perhaps not the direction I would have gone, but, at the end of the day, it doesn't diminish what it does, or how it does it, just how far away I can be when I do it. I can live with it.It'll do 4k, too, albeit only at 30hz. For most that will be fine, but not everyone. Gamers may run into issues here...in fact, lacking 4k 60hz is really the only serious negative some folks might actually have to consider. Perhaps the next generation will feature 4k60hz, or even 4k120hz...or, dare I say, 8k??? I guess we'll see later what the engineers at CKLau are working on for their next killer KVM. As long as 4k30hz is all you need? You're going to love this.
