The Dual View GCS1742 USB KVMP Switch brings dual head video functionality to IOGEAR's USB KVM switch technology. Now two dual-display computers can be accessed and controlled from a single console that consists of a USB keyboard, USB mouse, and two VGA, SVGA, or Multisync monitors. In addition, the GCS1742 allows the computers to share USB peripherals connected to the USB peripheral ports, such as printers, scanners, portable hard drives, etc.
Recognizing the importance of sound, this switch is also audio-enabled. A single microphone can provide audio input to each of the computers, and you can enjoy the audio output of each computer on a single set of speakers.

Question: we want to set one CPU, dual monitor configuration, the distance of one monitor to another monitor is about 20~30meters, can use this switch?
Answer: This switch would work, but a longer cable than what is included would be required for your displays. A video extender such as https://www.kvm-switches-online.com/ext-vga-141sr.html would be the best way to go this distance and maintain signal quality.

Question: Is the USB peripherals connection 2.0? and does this support Win 7?
Answer: The peripherals for this switch are USB 1.1 and the operating systems supported are Windows 98, 98SE, ME, 2000, and XP.

For a dual VGA switch with USB 2.0, we recommend https://www.kvm-switches-online.com/av4pro-vga-dual.html

Question: can I connect Samsung 900x3a laptop and Dell Dimension B110 desktop, and use two monitors.
Answer: Thank you for your inquiry. Yes, this unit will support dual monitors, dependent on both computers supporting dual monitors as well. It will not, however, allow you to share the laptop monitor with the desktop PC. Nor will it provide dual monitor support to a computer whose video card does not already support two monitors.

Because user environments vary so much, we cannot guarantee any particular setup will work; but if your computers are USB, VGA and from the supported OS's, it should work.

Question: Can I use this with Win 7 and is it possible to do a firmware upgrade for usb 2 compatible?
Answer: Thank you for your inquiry. Unfortunately, this KVM will probably have issues with Windows 7. It does not appear to provide full time EDID information to the attached computers. There is a flash upgrade port, however to accommodate hi-speed USB 2.0 would require hardware upgrades.

Question: What if I have a Macbook Pro (Early 2011). I only have 1 video outlet. Will this split it for me via 1 port from my computer?
Answer: Thank you for your inquiry. Unfortunately, no, it will not operate as a video signal splitter. This KVM requires two video out ports to function as a dual monitor unit.

Question: Could i have 2 secondary monitors in 1 laptop, and we can choose wich one will be turn on??
Answer: Thank you for your inquiry. Unfortunately, no, this unit will not operate in that fashion. This switch is used to share one keyboard, one mouse and two monitors (connected in a dual/extended desktop setup) between two different PCs. The monitors require two separate video connections and will display according to the primary/secondary monitor setup on each PCs operating system.

Question: I just bought this unit on the box it says it will support Windows 7 and usb 2.0 but below you say it does not. Has this unit been upgraded since the comments below. also is there converters for the VGA that will work to change to DVI?
Answer: Thank you for your inquiry. It is possible that this KVM has been upgraded to work with Windows 7 and USB 2.0, however, all of the material we have available makes no mention of windows 7 or USB 2.0 compatibility. We will keep an eye out for a change in the specifications for this switch and will update this page's specifications as needed.

In terms of converting to DVI, that is a tricky proposition. It will greatly depend on the type of signal needed and where it needs to be converted. Since VGA is an analog only signal, converting to a digital signal (DVI-D) would require some form of active conversion (something like this unit: https://www.kvm-switches-online.com/vga-dvi.html or this one https://www.kvm-switches-online.com/dvi-vga.html depending on which direction). Unfortunately, neither is a cheap option. On the other hand, if you can use the analog signal (DVI-A or DVI-I) you could probably get away with one of the pass through VGA to DVI-I adapters, but we could not 100% guarantee any type of adapter would work and would be reluctant to recommend it.

Question: I have a Mac G5 OSX 4.4.11 and a Mac Pro 2.5 OSX Snow leopard, each with dual display Mac DVI ouputs (convertible to VGA with adaptors). Can I use this product to switch between them using one Mac keypoard and USB mouse (wired)
Answer: Thank you for your inquiry. As long as the attached computers meet the requirements for this switch, it should work for your environment. It does provide native support for Mac style keyboards and is generally operating system independent.

Here are the updated requirements listed by IOGEAR:
2 x VGA monitors
1 x USB mouse
1 x USB keyboard

2 x VGA, SVGA, or Multisync port
1 x Type A USB port

Operating Systems:
Microsoft Windows XP (32-bit) SP3, Windows Vista SP2, Windows 7, Windows 8.x
Mac OS 9 to 10.x
Sun Solaris work station
Linux, UNIX and other USB supported systems*
*Additional drivers and support may be need

Question: I want to connect 1 dual-display PC and 1 single-display PC using this switch. Can this be done with this model and what issues am i likely to encounter?
Answer: Thank you for your inquiry. We do not foresee any issues, as long as both targets meet the minimum requirements. Because user environments are so very different, though, we cannot 100% guarantee compatibility for any particular setup.

One thing to mention: make sure the target with the single monitor uses the A cable for the VGA input.
