AccellB087B-006B UltraAV Mini Display Port to DVI-D Single-Link Active Adapter ATI Certified - Black

As a Mac Pro (early 2009 model) with an ATI HD5770 card, I was keen to use all three sockets on the back (two mini-Displayport and one DVI). It turns out that in order to do so you need a pair of *Active* mini-Displayport adaptors before you can use the DVI socket as the third display. The standard (cheap-ish) Apple adaptors are passive, not active, so these won't work. The Accell adaptors are Active (in other words they draw power), so using a pair of these meant I could use the DVI output to connect a third display.Works like a charm for almost half what the Apple equivalent would have cost.

Worked connecting 4 monitors to my Radeon Eyefinity setup... (HIS HD 6950 IceQ card)I tried the passive adaptors and they dont work.. I then got the Apple adaptors and they didnt work either.. Got these - worked a treat.. I've got one accell DVI and one Accell VGA adaptor..Sometimes has a problem detecting the VGA but I think thats because I've got it on a 5m VGA lead.. but if I switch off and on again it works fine again... So I'm guessing its interference.. Shorter cable and it never had a problem..

Did the job nicely - have an ATI Radeon 2460 graphics card to run the 4 screens we use at work. Upgraded to Windows 10 and the previous adapters did not work. After searching online it appeared I now needed active adapters. These did exactly what they needed to do - make the screens work again. Immediately

Perfect for attaching additional active screens to Mac Pro up to resolution 1920x1200 rather than forking out £80 for the apple dual link

Perfect!!!!!!!!!!

I bought an AMD graphics card expecting to run my three screens off it only to find that one needed to be an active mini display port, something I had not come across before. Found the Accell product on Amazon plugged it between my screen and graphics card and bingo problem solved.

Ordered one of these (Accell B087B-006B UltraAV Mini Display Port to DVI-D Single-Link Active Adapter ATI Certified - Black)for my Gigabyte AMD6950 2gb card as wishing to get the third monitor output.These looked okay for reliability from the reviews on here.On fit it did diddly squat - I had taken care to connect up with power off at both ends, it didn't even show the bios boot up, which instantly rang alarm bells, so I tried it with different monitor - the same result, tried it in the second display port - same results.On CCC did not see a third monitor neither did Windows.I tried the Accell firmware utility - this could not detect the adaptor in either port - I returned it to Amazon who promptly sent out another new adaptor (Accell B087B-006B UltraAV Mini Display Port to DVI-D Single-Link Active Adapter ATI Certified - Black)The result was exactly the same :-(I began to doubt my gfx card as I had never seen the DP working so before returning the replacement I ordered a (StarTech.com Mini DisplayPort to DisplayPort Adapter Cable - Video/Audio Cable - Mini-DisplayPort (M) - 20 pin DisplayPort (M) - 1.8 m - Latched) and tested my computer with a friends Display Port monitor - it worked straight away on either display port. (A relief that my card works)I will be returning this replacement adaptor - maybe I will be third time lucky??The question has to be asked are the (Accell B087B-006B UltraAV Mini Display Port to DVI-D Single-Link Active Adapter ATI Certified - Black) actually faulty or are they incorrectly labelled at the factory?Digging further on Amazon.com (not.co.uk) these adaptors do appear to ship dead or die soon after a few days or weeks! and digging on the various forums they commonly cause issues.Not sure now what alternative to try next

Purchased this for eyefinity for my 3 monitors, It worked for 5 mins then didn't work at all, I had to purchase a different display port adapter
