IOGEAR 2-Port USB VGA Cabled KVM Switch - 2048 x 1536 - Remote Button Switch - Plug n Play - PC, MAC, SUN - GCS22U

THE GCS1942 ($433) IS THE ONE TO GET IF YOU HAVE DUAL 4K MONITORS!I recently upgraded my Win10 PC to a pair of LG 32" 4K monitors, which have DisplayPort inputs, and this $433 (OUCH!) IOGear GCS1942 DisplayPort KVM. My previous setup was a pair of 27" WQHD monitors with DVI-D inputs, and used an older IOGear DIV-D KVM which is also a dual-view KVM. I can then run two computers with dual monitors.So, I tried FOUR other KVM's, and had issues all around. Issues like the monitors "forgetting" window locations, monitors powering down, monitors not being recognized, proper resolutions and refresh rates not being recognizable, poor video quality, and having to try adapters to connect everything. I spent DAYS messing with settings, drivers, adapters, resetting everything, clean installing everything ... what a hassle. I returned them all.Due to the reliability of my old IOGear KVM, which is easily 10 years old, I decided to suck it up and spend the $433 for this new version. Long story short, this KVM is worth every penny!!!Computers:* Custom PC with GTX-970 which has a single DisplayPort and single HDMI output. I had to buy an active adapter for my GTX-970's HDMI port.* A 2019 Dell laptop for work, with a USB-C Dell D6000 docking port, with two DisplayPort outputs.Results:YES, I WOULD BUY THIS AGAIN even though it was $433 - it is worth every penny.PROS:* Very good quality, just like my old IOGear KVM. Big metal housing, clearly labelled ports, easy to use.* 4 DisplayPort cables included! All you need are the DP cables to your monitors.* Proper support of 4K 60Hz resolutions, which looks flawless on my LG 32" 4K monitors.* Familiar (at least for me) hotkey operation, the same as my old IOGear KVM. Just press [scroll lock][scroll lock][enter] and you switch to the next PC.* This KVM supports the "monitor is powered on" protocol when disconnected. This is VERY important - it means that when you switch from one PC to the next, and then come back, all your windows are in the same place, the resolution is the same, and it's PERFECT.* Supports wireless keyboard and mouse. Do NOT believe the IOGear support folks who say you need a wired keyboard or their IOGear keyboard. I am using an HP wireless keyboard and mouse, which is 5-6 years old, and I simply plugged the wireless USB nubs into the appropriate ports on the back of the KVM. If you plug them into the "standard" USB port, then it will NOT work, so pay attention!CONS:* Switching PC's takes about 2-3 seconds, instead of the 1-2 seconds of my old KVM. Horrors! LOL. :)* It is pretty big, so check the measurements. I put mine on a shelf behind my monitors so I don't see it and don't care.* The cables are only 4' or 5' long. Adding an extra foot or two length would have been helpful for me, but that is most because I have an antique desk and have to run the cables out my PC, under the back wall, then 4' up to the top or a raised shelf on the back.* It's $433! I hate paying that much money, but then again my last one lasted 10+ years and I use it every day for work. Plus, this works FLAWLESSLY. I figure it's worth it.

I just bought this KVM. Here are a few thoughts after using it for a few days:REASON I BOUGHT THIS ONE: It had two USB 2.0 ports, and no PS2 ports. IOGear has had some great customer reviews for this, and other KVM products. I liked the fact that I plugged my own DVI cable into the switch to my monitor making cable length irrelevant. And finally, the one negative review I did see here was answered directly by an IOGEAR representative attempting to address the problem.PACKAGING: Nice cardboard box, foam wrap around all internal components, manuals were in color and in plastic bags, the manual content is complete but concise in English.QUALITY: Everything seems to be made of sturdy high quality components. The cables are thick, well insulated, and are generous length. You would only need to be concerned with cable length if your two machines are over 10 feet away from each other. There are plastic caps that cover the stereo cables if not in use and the cables themselves are color-coded. The cables plug into the switch ports firm and secure.HOOK-UP: Couldn't be easier. There was no need to look at the manual, everything is intuitive enough. There is a mini stereo jack cable for your left/right speakers and then one for your microphone. I have a 4.1 surround setup and I don't have a need for a microphone. Well, good news for those like me... just use the microphone stereo port for your rear left/right and you will have full 4.1 surround through the KVM. This was a great surprise, and it works.INITIAL IMPRESSIONS: One problem I ran into was that my Logitech MX510 mouse has 5 additional buttons. When run through the KVM it only detects a standard three button scroll wheel mouse. I never really used these buttons anyway, but it required me to reconfigure the mouse driver to speed up the cursor movement again.I hid the KVM switch behind my desk and only see the slim remote button. The bottom of the button has a no-slip rubber pad, so you can lay it on your desk flat and it won't really slide anywhere. The button itself is easy to find and press without having to look at it.Everything else worked great right out of the box. Since this is a digital KVM switch, you don't have to worry about quality of the signal. Either the signal arrives or it doesn't. You get perfect clarity or nothing at all. In my case, it's perfect. There is absolutely no difference in display quality when compared to directly connected the computer to the display.MY SPECS: Computer #1 is an older XP machine with a ATI 9800 graphics card. The other machine is an HP running 64-bit Windows 7 with a GeForce 260. The mouse is a Logitech MX510. The keyboard is an older Microsoft split ergonomic PS /2 keyboard. I used a USB adapter without any issues at all. I hooked up a PC Works FourPointSurround (with subwoofer) through the two mini-stereo ports. Like I mentioned earlier, you can use any equipment that uses two mini-stereo ports, it doesn't have to be a microphone.FINAL THOUGHTS: I am completely satisfied and this product has met my expectations. My opinion of IOGear has increased a few notches. When looking for future hardware, I'll certainly give IOGear a favorable consideration.
