Great KVM (Depending on your keyboard)

by Wingnutt on 12/27/2010

Love this kvm. It does everything as advertised, and video and audio quality are great. However there are a couple of issues. First the kvm ties up the numberlock key on your keyboard. This is a pain if you like to use the numberpad on your board as there is no way to remap that key. The real issue however comes if you have a Logitech G15 keyboard. Thankfully I have a ver.1 keyboard so my problems are not as bad as those with a ver. 2 board. On my board if you have it connected to the back of the switch the progamable Gkeys and the LCD display functions will NOT work. If you plug the board into the front usb accessory port the Gkeys and Lcd display work fine but you lose hotkey control over the kvm and have to change computers from the front of the switch. This is not ideal because most of us bought this board for gaming, so I have to reach down and change the connection for the board to game then change it back when Im done. People with a ver.2 board have reported this same issue plus a huge amount of lag. Some say its so bad it makes the board unusable. I am hoping that a future firmware upgrade will resolve this issue. Bottom line, if you have a G15 ver.1 and can live with switching the connection this is an excellent kvm. Video is great with DVI connection and sound through my Logitech Z5500 5.1 speaker system is excellent. I have 3 computers hooked up and have a 4th spot open to work on other peoples machines (my side gig). Also the ability to switch kvm, audio and the front usb accessory port independently or together is very useful. If you have a ver.2 board I would look elsewhere. Buy.coms price was also the best I could find online or retail by at least $40 with some sites wanting as much as $600 for this same item. Delivery was fast and well packaged and I received it undamaged. I hope this helps. Read More

Product Overview

IOGEAR's GCS1784 4-Port Dual Link DVI KVMP Switch with 7.1 Audio marks a revolutionary step in KVM functionality by combining IOGEAR's Display Emulation Technology with the widescreen graphics resolution of today's 30+ inch monitors, supporting Dual Link DVI, 2560 x 1600 (higher than 1080p HD) and ultra-high resolution up to 3840 x 2400.

This advanced KVMP can increase efficiency and save equipment cost for applications where high resolution, large or widescreen monitors are required, such as:

  • CAD (Computer Aided Design) and CAM (Computer Aided Manufacturing)
  • Desktop Publishing / Graphic Design / Video Editing
  • Medical / Surgical / Diagnostic Displays
  • High-End Gaming, where high and ultra-high video resolution is demanded

    The GCS1784 is equipped with IOGEAR's Display Emulation Technology which remembers your monitor's ideal resolution and refresh rate (EDID), making it possible to boot all your computers simultaneously, switch back and forth between computers, and still maintain the ideal video settings of the monitor. It also features two USB 2.0 peripheral ports for asynchronously sharing USB devices between your computers. A powered USB hub may be attached to the peripheral ports for added functionality.

    Completing the GCS1784 is its support for 7.1 surround sound systems, ideal for Blu-Ray Discs, High-End Gaming, and Video Editing. It offers an out-of-box solution including all cabling required for “Set-up and Go”!
