Product Description

The IOGEAR DVI KVMP Switch GCS1764 charts a revolutionary new direction in KVM switch functionality by providing an interface for today's digital monitors while integrating a 4-port USB KVM switch with USB peripheral sharing capabilities. As a KVM switch, the unit allows the user to access four computers from a single USB keyboard, USB mouse, and monitor, and also share among the computers peripherals such as external hard drives, printers and scanners.

The GCS1764's independent (asynchronous) switching feature allows the KVM focus to be on one computer while the USB peripheral focus is on another. The user can switch from one computer to another without interrupting print jobs, downloads or other functions being handled by connected peripherlas. This eliminates the need to purchase a separate USB hub as well as the need to purchase separate stand-alone peripheral sharers - such as printer servers, modem splitters, etc. It further improves on previous designs with DVI (Digital Video Interface) connectors, and the transfer of keyboard and mouse data to the computers via a fast, reliable USB connection. DVI supports both digital input (flat panel displays, data projectors, plasma displays, digital TVs and set-top boxes) and analog video input (traditional monitors and TVs). Fully compliant with the USB 1.1 specification - supports transfer rates of up to 12 Mbps DVI digital and analog monitor support - fully compliant with the DVI specifications Computer selection via front panel switches and hotkeys LED display for easy status monitoring Auto Scan Mode for monitoring all computers Complete keyboard emulation for error free booting Superior Video quality - 1600 x 1200; DDC2B Hot pluggable - add or remove computers for maintenance

  • Here's how to disable beep when switching
    There are a few "special" features that are available by accessing Hotkey Setting Mode (HSM).

    Invoking HSM
    For all Hotkey operations, you must use the number keypad on the right side of your keyboard.
    To Invoke HSM (PC-Compatible keyboard):
    1. Press and hold the Num Lock key
    2. Press and release the Minus key "-"
    3. Release the Num Lock key within one half second after releasing Minus key

    After HSM has been invoked, press and release B to disable the audible beep heard when switching computers. There are other HSM features too like changing key emulation for Macs. Refer to the manual for full instructions. Online here: [...]

    1. I had to run a USB hub like others in between the KVM and nForce motherboard PC (no big deal, I used the built-in hub on my monitor).
    2. The "Auto Scan" mode scans between all four ports, even if only three or less are connected. (You have to wait on the empty ports).

  • Tiny, easy to install, and works like a champ.
    Purchased this unit for the 1920x1200 resolution, the DVI and sound inputs, and the 4 ports. Unit exceeded my expectations.

    This unit is tiny! Less than 11 inches wide and 4 inches deep. It's about the size of a desktop 3 hole punch or a household spray can. The KVM cables and power plug into the back and the console plugs into the front. The unit is sturdy though. Case is metal and not plastic -- unlike some lower price KVMs. You can stack stuff on top of it.

    I connected it to a computer running Windows Vista and a computer running Red Hat Enterprise Linux. Everything worked flawlessly. All computers running at 1920x1200 @ 60hz. Switching from computer to computer takes about 2 seconds. Switching time might be less with smaller screens. Ports are hot-pluggable so you can move connections from one port to another without causing issues. The unit beeps when switching ports.

    Unit has an autoscan feature that cycles through all active computers. Autoscan displays each port for 5 seconds then moves to the next port.

    Oh, it comes with HOTKEYS! Instead of having to reach for the KVM switch, you tap the SCRL-LOCK key twice, press the number of the computer you want to switch to, then press ENTER. KVM switches and your hands haven't left the keyboard. (For us Linux people who type a LOT, that is a time-saver). There are other hotkey combos too.

    Finally, the unit has a 2 port USB hub built into the rear of it. You can plug in things like USB printers, webcams, and other things then share those among all computers too. How well that works, I don't know. Probably depends on what software you are using.

    Am very, very happy with the IOGear unit. Would recommend to friends, family, and co-workers.

    Some notes:

    1) Manual says max resolution is 1600x1200. Website says 1920x1200. Amazon says 1920x1200. Manual is outdated.

    2) When installing the KVM, you should power up KVM then power up your computers. I did it backwards and couldn't get 1920x1200. Also, some computers might have to be rebooted when plugging in the KVM port. Depends on hardware, video card, and operating system.

    3) When you start your computers after connecting to the KVM, they might show up with a lower than normal display resolution. Again, varies depend on hardware, video card, monitor, and operating system. Just adjust your settings.

    I'm so happy to have a KVM with sound. This is awesome!

  • Completely Failed To Work
    This KVM switch completely failed to work. I hooked up my Mac G5 Tower and my Dell PC and it wouldn't send a signal through to the monitor, a Samsung 24" flatscreen. Just.. nothing. A black screen. I tried restarting all of the computers, powering on/off the monitor, the KVM switch, and nothing worked. The USB light for the second computer wouldn't turn on either, even though it was connected properly. This KVM switch is worthless.

    I was unable to try the firmware upgrade because it required a serial port on a Windows machine. A SERIAL port? What year do they think this is? ...more info
  • bad customer service
    I have several of these switches in use and have been satisfied with their operation.

    After looking at a couple of the other reviews I have another point that should be considered by folks ordering this KVM switch.

    The switch is DVI-I and will switch DVI-D, DVI-A or VGA signals. The connectors on the KVM are DVI-I dual-link, I have not confirmed that the switch will do the dual-link mode and the IOGear website doesn't mention it.

    However the cables shipped with the switch are DVI-D single-link ones, they do not have the analog connections needed to deliver the VGA signal to the switch.

    That means you will need to get a VGA to DVI-I cable for any systems that only do VGA. You will also need a DVI-I to DVI-I cable to connect the switch to your monitor.

    Wikipedia has a good page on DVI for non-experts that explains all of this with pictures.

    Bottom line for me is that while not perfect it is good enough, I'll order another when needed and add it to the stack rather than switching brands and starting a second stack. ...more info
  • Easy to install. Intuitive to operate
    The IOGear Miniview DVI 4 port USB KVMP switch was easy to install and use right out of the box. I'm using it with a 1920x1200, 27" Dell monitor and a Dell XPS Gen 2 desktop and Dell XPS M1710 laptop via docking station. Also in use are a Microsoft USB Natural Keyboard Pro with internet, volume, play/pause, calculator, etc. buttons, and a Dell USB mouse.

    Computer and peripheral switching takes a second or two but I don't find this annoying.

    All of the accessory buttons on my keyboard function properly.

    If you start a computer without setting the switch to connect it to the monitor, keyboard, and mouse, then the computer will come up in a low resolution mode, but this is Windows operating correctly. It would be nice if Windows could automatically detect that a higher resolution monitor has been switched in after startup...

    I would prefer if the IOGear switch had some mounting provisions as I like to keep my desktop uncluttered. Also a remote control would be cool....more info
  • Great Product
    Other than the fact you have to have the computer selected you are booting up (otherwise the resolution gets funky), this product works great!! If you are in the market for a DVI switch, this is hands down the best one out there....more info
  • Excellent.... Easy to use and set up and works with my Wireless Microsoft Keyboard and Mouse
    OK So I have had issues in the past with KVM's and wireless keyboards and mice not working, but this works like a charm and have not had any issues with it.

    With my wirless microsoft dongle plugged into the front keyboard USB connector I'm able to switch between computers without having any keyboard issues (such as phantom key strokes, or wild mouse behavior). It works like a charm and would definitly recommend this product....more info
  • Works Well Except for Weird Sound Problem
    I just received this switcher, and for the most part it works well. I did discover that when first connecting it to a Windows box using PS2 keyboard and mouse, it's good to first connect box, let Windows discover it, then add USB mouse and keyboard to switcher. Linux did not have this problem (of course!). Anyway, as someone else mentioned, there is something wrong with the sound switching. The sound does get switched as expected, but it seems that the switcher is adding weird noises into the mix. Basically the switcher has the capability to leave sound and USB peripherals connected to one machine, while KVM (keyboard, mouse and monitor) is connected to another. This is actually a nice option, as I can listen to internet radio that is being played from one computer, while editing on another. But, unfortunately, weird noises get added to the sound when doing this. Really weird sounds! So, this box is almost great. I'm using it with a 1920x1200 monitor without any problems. The price also seems reasonable as well....more info
  • Works perfectly
    This product is my first experience with any sort of KVM technology. It works perfectly.

    The cabling that is included with the product is high quality and easy to use. I would avoid purchasing a KVM product that didn't include all cables. The "combo" cables that are provided are the only way you can neatly connect this much gear together. ...more info
  • Works Great
    This switch has been a lifesaver when wanting to share my 24" widescreen monitor with my PC desktop, work laptop and MacBook Pro. I rarely ever have more than one computer on at a time but I have not noticed any problems on the rare occasions when all three are on at the same time. I don't use the audio portion of this switch so I can't comment on that feature but for pure KVM I have no complaints. I was also very impressed that the switch came with all of the cables - a big plus!...more info
  • Works as advertised
    I've owned multiple KVMs over the years, and this is the only one that has ever worked exactly as advertised. Not only does this one actually support Logitech mice (I've only tried wired ones), and the Microsoft Natural 4000 (the web/home and favorites keys work!), but USB devices are not disconnected when the hub switches away. USB 2.0 works. I have never, ever been able to get hotkeys to work on the other switches, but this one makes it easy. (My last switch was a 4-port Raritan that promised to support what the IOgear one actually does--and it did, as long as by "support" one means "connect as a HID-compliant mouse and keyboard." I'm impressed, and I've never said that about any KVMs before....more info
  • Works great
    This product works great for me. Hooked up to it I have:
    PowerMac G5 with ATI Radeon 9600
    Core 2 Quad Ubuntu Hardy box with onboard Intel GMA X3500
    Macbook Core 2 Duo with Intel GMA X3100

    I first ordered a Startech Starview KVM, which showed no video from my laptop or Linux box. I returned it and got this instead. I should have gotten this from the start. Once I turned off the beeping and switched the keyboard mode to Mac, it works perfectly....more info

  • Needs update to add USB 2.0 speeds to get five stars
    I have two IO Gear GCS1764 KVMs hooked to three desktop and one notebook computers, two monitors, and a mouse and keyboard. The computers are Asus homebuilts x2, a Tyan homebuilt, and an HP notebook. The monitors are HP LP2465 x2 with USB hubs built in. The keyboard is a Microsoft KB4000 and the mouse is a Logitech MX300.

    The KVMs look good and are sturdy and reliable. IOGear warranty and customer support is excellent in my experience: one unit got bashed during a personal move and IOGear offered to service it up to three years later, while asking few questions about how it got damaged.

    I have used the KVMs for about a year or two but have not checked out all the features of the keyboard and the mouse since I did not load any of the special drivers for those, prefering to run them lean and mean with minimal drivers on my old Asus mainboard computers. I have not checked the audio switching functions either.

    So what does work? The monitor, keyboard, and mouse switching all work well using both the hot-keys and the front faceplate switches.

    The USB switching is reliable and works well in conjunction with the built-in USB hubs in the HP monitors (no conflicts have appeared). However, it chokes the speed down to USB 1.1, which is hardly forgiveable with USB3 just around the corner.

    IOGear (and many other manuafucturers) have neglected the realities of the enthusiast niche of this market by leaving an important feature severely constrained by slow speeds. USB flashdrives and portable hard disk drives that are plugged into my monitors' USB ports work noticeably slower when this KVM switch is wired into the loop. This product needs an update to improve USB performance.

    For USB 2.0 performance I have an Avocent SwitchviewDVI that I have used for 6 months for monitor switching using the front buttons (that function works well). Unfortunately, I have yet to connect anything USB to it, nor test any other functions of the Avocent. So I can't say whether the USB switching works well, or whether it performs at USB 2.0 speeds (as advertised). Hopefully, I will get some experience with the Avocent by next year and post a review on that product.

    UPDATE 29 AUGUST 2008: I now have several months experience with the MS KB4000 keyboard drivers loaded and have experienced no conflicts with the IOGear switch.

    I also have some more experience with the competing Avocent Switchview DVI. When I tried to use an Avocent switch to replace the IOGear switch that I was using as a main unit (to switch Video 1 signals as well as mouse and keyboard signals), the Avocent would drop the keyboard and mouse offline very quickly, rendering the computer useless.

    I put the IOGear switch back in place and all went back to normal, albeit with USB 1.1 as a lingering speed limitation.

    I can still successfully use an Avocent switch as a simple second DVI switch to route Video 2 signals from various computers to my second HP 24" monitor. I have not tried switching USB 2.0 peripheral devices with the Avocent.

    IOGear has finally introduced some new products that include USB 2.0 support. In particular, I look forward to trying the IOGear GCS1204 switch with it's many improved specifications, including USB 2.0 support.

    With USB 3 being introduced soon, it remains to be seen if this is too little, too late, once again. Let's hope that someone steps up to the plate and provides a switch with USB 3 support early on in the next transition cycle. Growth of the enthusiast KVM market can only occur if state of the art products are there to purchase. Of course, these products must also work well to build consumer confidence that they are a worthy purchase....more info
  • Just what I expected
    This is a great looking DVI kvm. The buttons on the front allow you to quickly change the picture around to any of the four inputs. If you want to switch the usb as well, you simply hold the button down on the item you want a bit longer. Being able to quickly switch around the video to check on the status of something is a nice help. The picture quality out is very good as well, no complaints (I'm using 1600x1200). The cables that come with it are of good quality and worked well. I have three computers hooked up to it now. MacBook pro (OSX), hp laptop (vista), and another PC (XP pro gaming rig). Switching around between them works without a hitch (including the sound). The only thing I've noticed is that on startup, the computer that is starting likes to have the kvm set to it or else it can't seem to figure out the capabilities of the monitor properly. So when I start it, I just make sure the computer I'm starting has "focus" and everything is fine. Compared to the other DVI kvm's I looked at, this one is better looking, functions well, and was usually the cheapest price. Go figure....more info
  • Works great
    I am using this with my Linux server and 2 Windows machines. It works fine. I am not using the front keyboard and mouse ports, due to my multimedia keyboard and 7 button mouse, just the usb on the back. You have to hold down the button on the KVM to get the usb to switch computers. Can't use the hot keys this way, but not a big deal. If you boot a computer and it is not selected the resolution defaults to 1024x768. Running computers at 1680x1050 on a Samsung 226BW, no problems. Only use this if you are using DVI don't use if you have VGA with DVI adapter (VGA KVM's are less $). No sound issues with my 3.1 system, sounds the same with no static or noise. Supplied cables could be a little longer but work fine....more info
  • Great KVM switch for DVI - But only supports USB 1.1
    After looking for a KVM that worked well for DVI that supported higher resolutions that didn't cost an bundle, I was excited to see when this one dropped in price so I picked it up. It was easy to set up and worked well with all of the computers I had it connected to. It was only after I had it installed that I noticed it only supported USB 1.1 which I guess is fine for using only the mouse and keyboard, but if those are USB 2.0 and are connected to a USB 2.0 hub with other hardware such as a USB hard drive or thumb drive, the data transfer rate suffers. I ended up moving the hub off the KVM as a result. For everything else, the KVM works great....more info
  • Could not get to work at 1920 x 1200
    After having problems with another Iogear KVM switch at 1920 x 1200 (over VGA, not DVI) the reviews here that mentioned success at that resolution had me optimistic. Alas, I could not get this switch to work properly with 2 PCs at that resolution. The best I achieved was a display with lots of lines dancing around, and random red pixels. Worst case, there was just a band across the middle of the screen - the video changed every time I cycled ports. Another computer running at 1600 x 1200 - which is within the published spec - displayed the same degraded video. Iogear tech support was friendly but ultimately not able to offer any help other than to point me to the GCS1204 which is double the price. That switch is a dual link DVI for much higher video bandwidth, so I suspect it actually will work for my case.

    It's unfortunate, as this is a nice KVM otherwise. The previous Iogear KVM I tried is the GCS1758 (I plan to have a 5th device for work/testing, so really want 8 ports) and while it's a well made KVM with some nice features it also had problems with video at 1920 x 1200.

  • Excellent DVI KVM but USB 1.1???
    I really like this product but it has a major shortcoming. It fixed my issues with connecting my macbook to non-apple monitors. That's a HUGE plus in my book as I was about to throw out my macbook in favor of a lousy PC simply because of monitor connectivity issues. The bad news is that the built-in USB port that you can manually switch with the KVM is only USB 1.1! What were they thinking? This is fine for USB audio devices and printers,etc but if you were thinking of using it to connect external usb drives like me, you'll be quite upset at the lousy 12Mbps connection you'll get with it. Other than that, it works perfectly and the audio switching is a cool function that I use a lot. If they had made the onboard usb 2.0, this would be the best 4 port DVI KVM solution available on the market, both in price and quality. If connecting usb drives is not a requirement, then this is the best 4 port DVI KVM solution out there....more info
