VisionTek Active Mini DisplayPort to DL-DVI Adapter Cable for Mac and PC (900640),Black,One size

Tried it on a samsung s32D850 (DVI,HDMI,DP) on its DVI input from an Nvidia quadro P400 (4xmDP) under win10x64. Nothing - blank screen.The screen used to run from a win 7 PC with DVI only. I find mDP is unreliable - tap the cable and the picture is gone - poor connection. In contrast, DVI is as solid as a rock. Newer need not be better . 3 stars for delivery and quality feel of the product

Bought to drive one of those Korean 27" monitors 2560x1440 that require DVI-D.Connected it to dell WD15 and it worked albeit only with one of my three cables that claim to be DVI-D and that worked with stationary computer.

Works reliably, first time. I am using this to run my LG W3000H monitor from my laptop.The monitor is 2560x1600 60Hz and requires DVI-D dual. This adapter does that from my laptop's mini DisplayPort ( v1.2, I believe ).Remember to use a proper DVI-D dual cable from the adapter to the monitor.

Doesn’t work for Cinema Display with mid 2012 MacBook Pro

Simply didn't work from a MiniDisplayPort to a 144Hz 1080p monitor. No display at all, not even a low refresh rate. Very disappointed. I have since returned the product.

Got full and completely stable 2560x1440 resolution with a Macbook Pro early 2011 and a ViewSonic VP2770-LED. Very pleased with this adapter.

Short summary: It doesn't support driving a Dell 30'' 3007 at 2560 x 1600 resolution. It can support 1280 x 800 but that's not what I was expecting from this dual layer DVI product. 2 stars for the product quality (seems robust and well manufactured) but I returned it for another product that thankfully worked.

Doesn't work with the QNIX qx2710, if that's why you're buying it, don't buy. Not entirely sure it is active.
