VisionTek Active Mini DisplayPort™ to Dual Link DVI converter is a new generation Mini DisplayPort™ to Active Dual Link DVI converter that receives both video and audio streams from an upstream DisplayPort Source link and converts to a Dual Link DVI output. The Mini DisplayPort to DVI-D Dual-Link adapter lets you connect your DisplayPort video source to any DVI-D display, eliminating the expense of having to upgrade to a DisplayPort-capable monitor. The Mini DisplayPort adapter offers an active conversion and easy connectivity directly without any external power input and is able to handle full dual-link resolutions (up to 2560x1600). Use it to mirror your display to another monitor, or extend your desktop to increase your workspace.

2 out of 5 eggsWorks...sorta

Pros: It does convert mini-DP to DVI

Cons: Does NOT support dual-link as stated. The max I can get from either of the ones I bought is 1920x1400. The ONLY way I can get it to work on my 27" 2560 x 1440 is if I change the refresh rate, but when I do that the adapter will only support 800x600 resolution. Definitely not what I wanted.

Other Thoughts: If you're planning on doing 1440p or higher, this is a hit or miss for you. If it's less, you might be ok.

1 out of 5 eggsdoesn't work

Pros: None.

Cons: Does not work with a 2560x1600 monitor. (The only reason you need dual link is for higher than 1920x1200 resolutions.)

Other Thoughts: Looks like usb power may be required for WQXGA, as it is for the mini-displayport adapters I've also used.
