Review: Better than the rest by a huge margin, but limited support for 1440p and 4K (30Hz only) - UPDATE: Limited refresh rate support makes this switch INCONVENIENT for use with 4K MONITORS. Not lowering the rating because the switch works well for what it is designed to handle. I've tried several 4-port HDMI switches recently. This one, although almost twice as pricey, wins my vote. Some of the "pros" below seem obvious, but you'd be surprised how many other switches do not support one or more. Pros: 1. Remembers monitor resolution (EDID) and sends it to each connected PC even if it is currently disconnected from the monitor. There are no monitor adjustments each time the PC is connected, there are no 1024x768 tiny Windows screens when PC is rebooted without being actually connected to the monitor. It's what the doctor ordered. (See the "not tested" comments though). 2. Direct switching via keyboard shortcuts. You can switch directly to any PC, no need to cycle through every PC. 3. Ability to switch the monitor only, leaving the keyboard and the mouse attached to the other PC. If you do any kind of cross work across PCs, and do not have another keyboard lying around (or no room for it), this may be handy. 4. Support. The support site has all the manuals, even firmware upgrades. Cons: 1. Switching is not instantaneous. It takes a few seconds for the picture to appear. But this happened with every switch I tested. Perhaps it is my monitor or perhaps this can't be avoided. 2. The switch doesn't handle resolutions above 1920 x 1200 well. Only 30Hz refresh rate is supported. This presents a problem with 4K and 1440p monitors. These montiors present EDID resolution data to the computer indicating that 4K @60Hz or 1440p @60Hz is supported. This makes the computer switch to the best available resolution supported by the monitor but the switch cannot handle it. Then... no picture. Unless a monitor is connected using a different cable to bypass the switch, no BIOS settings or graphics card settings are going to be accessible. Not tested: * How keyboard emulation may affect gaming speed. * Analog sound and mike. Sound is delivered via HDMI in my setup.
Review: Solid switch with minor room for improvement - I am using this to switch four relatively disparate devices (two PCs, a Mac, and a Raspberry Pi) using a PS/2 keyboard and a USB scroll wheel mouse. I had to fiddle with mouse settings to make the mouse work (before disabling mouse emulation the mouse would move only down and to the right, and even that was erratic). Switching is annoyingly slow, taking about 3 seconds, but honestly I don't know if that's the monitor re-syncing to the new HDMI signal or the switch itself, and for the use I am putting it to this is not a big deal. With a guarantee of at least one USB connection and at least one HDMI connection coming in, it would be nice if it could draw power from one of the controlled devices. Adding Yet Another wall wart when you're already controlling four plug-hungry computers is just insult upon injury -- but I guess it's better than three more monitors! Build quality seems solid, and while it won't win any aesthetic design awards its appearance is quite acceptable. Overall I am quite happy with this switch. I type very fast and have noticed no glitching of the keyboard, and HDMI settings seem to be passed through with enough attention to detail that all resolutions/color spaces/etc. configure themselves appropriately. The command beep is an appropriate pitch and volume for a relatively quiet office environment and infrequent use (it would probably be lost in a rack room and would become quite annoying for very frequent switching). The status LEDs are maybe a little bit bright for the selected display, but not egregiously so. (This is probably because dimmed LEDs are used for unselected-but-available displays.) Update: Two years down the line, I would report that I do experience some glitches with both the keyboard and mouse. When using one port on the KVM and a computer on another port boots up, the keyboard stutters and becomes unresponsive for a few hundred milliseconds at a time over a few seconds. This causes missed and/or repeated characters. This isn't a huge deal for me because the machines on my KVM seldom reboot while I am using other machines, but it is annoying when it happens. The mouse also sometimes gets "lost" when switching back and forth frequently, and has to be unplugged from the KVM and plugged back in. When this happens, the mouse seems to simply not report to the selected computer at all, and neither mouse movements nor button presses register. Re-plugging it fixes the problem. This problem is more annoying, but infrequent enough that I haven't replaced the switch.

## Questions & Answers

**Q: does anyone have any experience using this with a higher resolution monitor, my monitor is 2560x1440**
A: I have been using this KVM switch with a 34" LG monitor at 2560x1080 resolution for a couple of years now with no issues. It is curious that the specs say 1920x1080 max ... perhaps that's the highest resolution that IOGEAR will provide support for, but it seems like a number of people are using it successfully at higher resolution.

**Q: need manual**
A: Manual link has changed. Current link as of 12/5/2018:
https://www.iogear.com/support/dm/manual/GCS1794

**Q: Does this switch work for pre post to be able to enter fucntion commands and enter bios etc. prior to drivers loading?**
A: I rebooted Ubuntu machine and pressed F1 to get into BIOS - no problem.  Tried several times with Win10 but couldn't get into BIOS.  I use a Logitech wireless keyboard and mouse with my 4 port IOGeear MiniVIew.  I suppose if I wanted to get into Win10 BIOS, I'd just take the Logitech dongle out of the 4 port switch and into the Win10 PC.

**Q: How long are the cables?**
A: There are 4 sets of cables with connections for USB2.0, HDMI, plus plugs for sound and microphone included, and each set is about 72 inches long. A nice feature are the sliding cable guides, that can be moved to adjust the separation of the cables to suit your computer port positions.  The switch has worked well for several month, without issues.

### ⭐⭐⭐⭐⭐ Best KVM for HDMI Video
*by T***E on January 16, 2016*

Pros: • Well packaged with recyclable materials • Sturdy and well-made housing on unit, stays put when pressing buttons on unit. • Cables are high quality and flexible. • Ports for cables are primarily on the back with audio ports and one USB on the front. • Functionality is outstanding. Switching always works via buttons or hotkeys. • Varied devices that it can control • Takes up less space than competing products. Cons: • Expensive, but the quality is worth it. • Annoying beeping when switching devices is too loud. Had to turn it off. See other thoughts • Manual is not complete and website does not help much. • My laser pointer mouse did not work in the “mouse” USB port, which I have read is an issue for some mice. Moving to one of the other USB ports solved the problem. No issues. Other Thoughts: • My setup. I have four HTDI devices plugged into this device: Desktop PC w/ Windows 10, Laptop w/ Windows 10, Sony PS4, and Microsoft Display Dock for my Windows Phone. All work flawlessly. Each device shares keyboard, mouse and one monitor. • Switching between devices is easy with keyboard commands (ScrLk, Scrlk, 1-4) • To turn off/on the beep: invoke Hotkey Setting Mode by pressing and holding CTRL, then pressing and releasing F12, then releasing CRTL then press the `b' key. • I have used other competing products and they do not compare to this one for ease of use, quality, and reliability. After one month of heavy usage, I am very pleased with this device.
