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
. 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
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!>>
