Widescreen Gaming Forum

Ok so I have an accell ultraav mini displayport to dvi dual link active adapter and I've noticed some flickering (not total blackouts) in the dp adapter monitor and blurry text. After doing some digging I've found that it's definataly the dongle causing it so I called accell today and they informed me that they have made a revision on the firmware and I may have bought an adaptor that was distributed prior to the rev. So i looked at my sticker and sure enough it doesn't contain the new f/w rev. Rather than sending it in for an update I am going to return it and get a new adapter but I'm afraid that he store still has the older versions so I'm looking at the apple mini dp to dvi dongle. I'm just curious if anyone here is using one and if so how is I performing for you. Any blurry text or flickering during gaming? Also I have had problems setting up bezel management because I get an error about resoultions not supported with my current one. I'm contributing it to the fact mine needs the update. Any input would be great because I would like to have some feedback with the apple dongle before i purchace it. Any weird quirks with them not being used with Mac hardware? Thanks alot in advance

The Apple Display port adapter is well cited to be one of the biggest steaming piles that Apple has released in the last 10 years.

Haha that's saying a lot.

I used the Apple adapter for the third Eyefinity screen, with some quirks, but it worked. I then switched up to that new Sapphire DP -> DVI adapter (made just for Eyefinity, released recently), and virtually all issues have disappeared, it seems to work perfectly, and it was only 30 bucks.

I do have a perfectly good Apple adapter now sitting in the closet, but can't really recommend it based on the newer options.

I should probably note - that new Sapphire adapter that's working so well is standard Displayport. You would need the additional adapter to bring that down to mini-displayport for the 5970.

no worries. my 5970 came with a mini displayport > Displayport. thanks you for the suggestion

If you would be willing to try something new; monoprice released a new mini displayport 1.1 to DVI-D DL active adapter. Its under $70.00, and monoprice has a 30 day free shipping no restocking fee on returned items policy.

I would assume it could support 120hz HD resolutions just like the apple adapter. But thats something you would have to test for yourself.

I like the apple one. Sure its has its bugs and doesn't work well for most people but if it does work it has the possibility to run at higher than 60hz which can be important in the future.

Mine works well for me.

I currently use 2 of these apple adapters. The oly reason I bought them was because they were super cheap for an active DL DVI display port adapter and they were mini display port to boot. But they suck. I have to power cycle them every once in a while. They start flipping shit when you change resolution and then have to power cycle them. I cant get past BIOS with them being powered on. I have to wait until after windows boots up to turn them on. It's really really bad.

The frustration and hair-pulling begins anew!

After waiting for over two weeks to get the proper ACCELL Mini DisplayPort to DVI-D Single Link ACTIVE Adapter with an ATI Eyefinity Certified Sticker right on the front of the package, I'm totally frustrated that it DOES NOT WORK!!!

I have now tried both Mini DisplayPorts on the HD 6870, two different DVI cables, and on two different monitors.

All I get is a black screen.

Otherwise, I'm getting the Power On indicator light, I also get the "No Signal" on screen message whenever I disable the display from within CCC or the Windows Screen Resolution option.

I can't even get a display when I try to simply Duplicate or Extend the display.

And this was supposed to be easier.

No, I am NOT happy!!! :evil:

Is the adapter getting enough electricity? That seems to be the most common cause of issue.

I have a 1000W PSU as shown in the specs in my signature below. That should be ample.

He is talking about the current requirement for the adapter. Some motherboards cannot supply the current for the current draw of the active adapter. In some cases like this; the adapter needs to be pluged into a dedicated power source with ample current. Find out how many amps the adapter draws; should be printed on label somewhere on the device. Then go do walmart or radioshack and find an adapter that can output at least that much current on the DC side; so make sure you are reading the DC current and not the AC current. Give that a try and supply some feedback.

The active adapter I have does not have an external plug and therefore does NOT plug into any USB port on the motherboard. It is all contained in one unit that plugs only into the video card's Mini DisplayPort. So, the adapter is NOT drawing power from the motherboard, but from the video card which is drawing power from the PSU via TWO Six-pin plugs. And, those two Six-pin plugs are from a 1000W PSU. And, to be very clear, this IS an ACTIVE adapter as stated right on the package AND on the adapter itself.

I went through this ordeal with the HD 5770 trying to use one of those other active adapters that DID plug into a USB port for power. That did not work successfully (as reported here elsewhere) and I finally found an excellent working solution using a DP -> VGA adapter made by Monster. Sadly, though, AMD decided to change from the standard DisplayPort to two Mini-DisplayPorts...rendering my previously excellent working adapter useless for the new video card.

EDIT: I updated the link in my original post as it apparently got truncated. Here it is again....

Have you tried a single monitor configuration with just the displayport adapter hooked up?

Check to see if at least you can drive one display from that adapter.

It doesn't even display at POST. So, no, it does not provide a display....PERIOD.

I've tried a couple more options. I will NEVER EVER buy another ACCELL product. NONE of them have worked for me and they ignore any email support requests. It's now been almost FOUR days since my email to them and, in spite of a clearly noted promise to respond withing 24 hours, I have not gotten even the decency of an acknowledgment that they even got my email.

However, I DO have Eyefinity working again! YAY!

How?

I bought a Mini-DisplayPort -> DisplayPort Adapter and then got another Monster-brand DP -> VGA adapter. Voila!
