Summary: I bought two of these to set up at my home and work offices. I could not get them to work. And it's not because I am not computer savvy, I am a software engineer, they just did not do all they said they would. I could get the monitors working on one machine, never both. And I never got a keyboard or mouse to work. Unfortunately for me, I am out the money on one of them because I waited too long to try to set them up and it was too late to return it.
Summary: I called StarTech support (after reading the online manual on their website) before ordering this so I could be 100% sure it would work. They told me exactly which cords I would need. I was able to order everything online except I did need to purchase two VGA cords. Not a big deal because this switch does exactly what I need it to do. Here is my set up: 2 CPU's, 2 monitors (one VGA, one DVI) - all hooked into the switch.
Summary: After trying to install it myself, I was unable to get it to work (desk top & lap top). I opened a Chat with StarTech support, and the tech had me do many of the things I tried myself but to no avail. "It might be bad cables", he said... Frustrated, I called a Geek Choice tech to come to my home to set it up. After 2 hours (and $250 of my money) he determined the device was defective... It's been sent back.
Summary: Considering this is the cheapest unit I could find that does what I needed, I am extremely happy and impressed. There are some mixed reviews on here which made me hesitate. I think it comes down to what kind of system u have. I have win8 dual screen + linux ubuntu dual screen I have a strange setup. My windows box has dual screen but I also have a HDMI cable attached to my TV. When I switch on my TV one of my monitors goes off.
Summary: It manages to do a nice higher resolution share, which is great, but the ports on the back (DVI) are so closely aligned that it's nearly impossible to put two standard DVI cables next to each other. Thankfully, I had an unusual cable that did fit, but if I'd tried to use two standard DVI cables, one of them wouldn't have made the cut. Seems like a design flaw.
