Hello, the issue I am having is that the card is does not detect a second monitor. I've used all the suggestions from the FAQ and many online sites for recommendations and nothing has worked.

. My card is a XFX Radeon R9 290X ENFC. It has Two DVI-D ports, One DP, and One HDMI.
. GPU is cooled using a Kraken X60 and Kraken G10
. CPU is Intel I7-4790K
. MB is Asus Maximus VII Hero
. PSU is Sea Sonic X Series X-850 850 Watt Modular Gold
. RAM is G.Skill Sniper Series 8GB (2 x 4GB) DDR3
. OS is Windows 7 x64 SP1

Both monitors have a DVI-D port, I am NOT using any adapters. The card only works for one display. The top DVI port is the one I am currently using that works. The bottom DVI won't work as a Primary or a secondary. The Display Port will work as a Primary, but not secondary. I haven't tried the HDMI as I do not have a monitor with that connection.

I have switched the cables out to new ones but that did not work and I have tried both DVI-D 24 pin as well as 18 pin. I have tried both monitors using the top DVI port and both monitors work when connected to that port, but neither will work on the bottom DVI port.

If I use the Display port, both monitors will work as the Primary, but if I try to add a second monitor using either DVI port, that second monitor will not work. Something I have noticed is that the secondary monitors, no matter where they are connected (top or bottom DVI, DP), the monitor just goes black. It does not display a message of "No signal". The "No Signal" message will only appear when I disconnect the second monitor from the card.

Also, no matter where I connect the second monitor, the "Screen Resolution" page will not show a second monitor, neither will the Catalyst Control Center.

I downloaded an EDID viewer and the computer will show both monitors but only the one that is plugged into the top DVI port shows as "Active".

I have uninstalled the driver several times, using an older driver and the most current. I tried installing the drivers using CCC as well as extracting the driver from CCC and just using that. None of those ideas worked.

I have even wiped the HD and reloaded windows 7 x64 SP1. After the reinstall, both monitors would work in the UEFI Bios, and during the installation of windows. After a reboot during the installation (I don't remember which part of the installation as I wasn't paying attention thinking the problem was solved), the second monitor stopped being recognized. During The first installation, the second monitor stopped being recognized during windows updates. The second installation of windows, I did not run a single Microsoft update.

I do have another tower I can put this card into to test if it works or not in another system, but I have a water cooler attached and would love to avoid having to remove it and put it into another system just to test this (will if I have to though).

At this point, I am pretty much stumped. If anyone has Ideas for something I should try, I would greatly appreciate it!

Are both displays the same type / model of monitor?


I had an issue with an ASUS VE228TR that suddenly stopped being detected on DVI connection using most of the 14.x drivers. My other monitor - AOC e2250Swda works every time.
