Hi James,

Thanks for posting. I would be happy to help with your DP-HDMI adapter.

When is comes to multiple display support on AMD cards, sometimes the devil is in the details. Can you let me know which exact brand and model 5570 card you are using? The reference on AMDs page -> http://www.amd.com/en-us/products/gra… only shows the reference design with a single DVI output, so that obviously doesn’t match what you have.

Can you also let me know what brand and model monitors you are using, and confirm the cable types (what connector is on each end) and any other adapters you are using besides the Plugable Active DisplayPort to HDMI adapter?

Just let us know the additional information when you have a moment and we’ll go from there.

Thank you,

Bob

Thanks for the response
This is the best I can do for online info; http://www.game-debate.com/hardware/i… HD 5770 1024MB
Monitor is a BenQ GL2460-B using HDMI. At them moment I’ve used both an amazon basics hdmi cord and had it going through fosmon 3x! switch. I since circumvented the switch with an xbox hdmi cable.
I’m including a screen cap of the graphics card info to support the info in the link !](https://d2r1vs3d9006ap.cloudfront.net/s3_images/1341768/GPUinfoscreenprint_inline.PNG?1452104463)](https://d2r1vs3d9006ap.cloudfront.net/s3_images/1341768/GPUinfoscreenprint.PNG?1452104463)

Hi James,

Thanks for getting back with the info and the screenshot. A few additional questions…

The monitor model you mention doesn’t seem to have an HDMI input -> http://www.benq.com/product/monitor/g…

Is your model the GL2460HM -> http://www.benq.com/product/monitor/G… ? I just want to make sure I have all the specifications correct.

Can you also let me know the specific model monitors that are connected to the two DVI ports, and confirm that they are both using standard DVI to DVI cables?

Thank you,

Bob

Hi bob
Yes my monitor is a GL2560HM.
ok so the two monitors on the DVI are actually native VGA DVI to VGA cables. They are both ASUS VH192 version: VH192D

Hi James,

Thanks for getting back with the additional information. Looking at the specifications online for your Asus monitor from Newegg.com (Asus’s site does not list the model information anymore) -> http://www.newegg.com/Product/Product… I can see that only inputs available are VGA.

Multiple display support higher than two displays referred to as Eyefinity by AMD can have very specific requirements to work in some cases. AMD has FAQ entry with a video that speaks to this in greater detail here -> http://support.amd.com/en-us/search/f… Per their guidelines, our adapter ‘should’ work, but to help rule out a subtle difference between your setup and what AMD references, can you try disconnecting one of the Asus VGA displays temporarily to see if the BenQ monitor connected to our adapter starts working?

Thank you,

Bob

Hi bob
I have disconnected my left ASUS display and still nothing on the BenQ.
Also while I have my one monitor disconnected I plugged the BenQ into the HDMI port on the graphics card and was able to get picture.

James
P.S. also tried running just the benQ through the adapter with no other monitors attached and still did not get a picture

Hi James,

Thanks for getting back with the results, and thank you for your patience while we isolated it down. It looks like the adapter is faulty, and we will of course send a replacement.

If you would, please send us an email at support@plugable.com with ‘Ticket 129843’ in the subject line and please include your Amazon Order ID number and preferred shipping address and we’ll get the process started.

Thank you,

Bob
