XFX R9 280X won't detect third monitor with Mini DP.

[AfeRena]

Hello everyone. I got a little problem that I would like to get some help with!

I recently got a HDMI to Mini-DP adapter to plug in my GPU and make my TV a third monitor.
(I got my main monitor plugged in by the HDMI and my second monitor (a VGA one) with an DVI adapter)
When I plug in the Mini-DP, the PC makes the "I found a hardware" sound, but I can't seem to make a third one connect. My GPU drivers are up-to-date.
When I hit Windows+P and select Extend, it cancels my main monitor and then uses the TV and my second monitor. Still, only two active at a time.
In the "display settings", if I choose the third one to "extend desktop to this display" and hit apply, the following message appears: The display setting could not be saved, please try a different combination of display settings"

I'm running on Windows 10 64bit.

Thanks in advance for any help!

Please download the newest drivers for the card from AMD's website. Install them and take note of the folder created within C:\AMD\ and delete all subfolders except for the new installation. Restart and try again.

Also try plugging the DVI adapter into the other DVI slot.

Ok, I'll try that!

 

[AfeRena]

Ok,

Putting the DVI adapter on the lower slot didn't work. My second monitor went black, but the TV got a signal and showed my second monitor screen and things.

I installed the newest driver and I just want to be sure. I can delete everything except the one highlithed? https://i.imgsafe.org/71491902ac.jpg

Yes

 

[AfeRena]

Deleted the other ones and restarted the PC, but still nothing. Can't recognize more than two screens.

 

[weberdarren97]

Try all possible combinations of DVI ports and MiniDP ports, restarting each time.

 

[AfeRena]

I'm sorry. I'm kind of a newbie to this whole "more than two monitors" thing. What do you mean by all possible combinations?

 

[weberdarren97]

Try each DVI connector on the card. Also try each MiniDP connector. Try using all possible combinations of these four connectors.

 

[AfeRena]

Tried all of them. All possible combinations restarting everytime, but still no results. Only two active at a time.

Please post the model number of your card. Once I have that, I will contact XFX and see if they have a fix for this.

The model should be either R9-280X-TDFD or R9-280X-TDBD.

 

[AfeRena]

I think mine is a TDDB, right? It's a little hard to see:

[weberdarren97]

TDBD, yes.

I will post another reply once I gather some more information on that model and have a chat with XFX.

Ok, man!
Thanks a LOT for all the help! I really appreciate it!!!

 

[weberdarren97]

Wow I love XFX customer support. I called in using my company name and said I had a client having an issue with one of their graphics cards... It wasn't even thirty seconds before an actual human answered the phone and he was knowledgeable on the issue!!

Anyways, here's what I found on out on the phone: you need to use an active adapter or else the chipset will reject the signal. That is the root of your issue.

Here is an active adapter on Newegg.

 

[AfeRena]

Hahahaha they sure are great!
But I see now. I'll have to find one of those in my country now (Brazil)! But at least I know how to make it work!

Thanks a lot for all the help, man!
