3 Display Setup Not Working (HELP)

[Ragatag]

Hi!!

I just recently bought a SAPPHIRE R9 280 (Supposebly has 6 monitor capability)

Right now I am attempting to use the following screens for a 3 screen setup...)
1) 24 Inch Screen (DVI) -------- 1x DVI
2) 21 Inch Screen (VGA -> DVI) -------- 1x DVI
3) 42 Inch Flat Screen TV (HDMI -> DisplayPort) -------- 1x DP

THE ISSUE:
I can use my main screen 1) and another screen, either 2) or 3) but not 1), 2), 3) together...
My PC detects all 3 screens but it will not allow me to use all 3 simultaneously, any suggestions guys??

I eblieve that if you want to use more than two monitors you have to use displayport

 

[Ragatag]

Thanks for your response. For the 3rd monitor, I am using a DisplayPort. Do you mean that I have to use DisplayPort for all monitors?

Im confused as to what you are running your displays off, Are you running 1 monitor off dvi, one off vga and one off hdmi on the card? The connection on the card is the important one not on the monitor

 

[Ragatag]

My card has 2x DVI, 1x HDMI, 1x DisplayPort.

I'm currently using the below setup:

1) 24 Inch Screen (DVI) -------- 1x DVI
2) 21 Inch Screen (VGA converted to DVI) -------- 1x DVI
3) 42 Inch Flat Screen TV (HDMI converted to DisplayPort) -------- 1x DP

Actual connection to the card is 2x DVI, 1x DP (After conversion)

You need to use an Active adapter to go from HDMI to DP <- You may have a passive adapter.

 

[Ragatag]

This might be the answer!! Thank you.

Just ordered an active adapter, let's see if it works out.

 

[unknownofprob]

what was your old adapter?

 

[Ragatag]

It's an average HDMI to DP converter

That wont solve his issue he already said that he can use that monitor with another one, just not all 3 at once. If the monitor isn't working that's not the issue. You need to have one monitor connected to the displayport on the card for 3 monitors.

One of my monitors is already connected to the DisplayPort. I was looking into Active/Passive Adapters and my understanding is that it has to been an active adapter on the DP or the 3rd monitor doesn't work.

Not true, if he has a passive adapter the issue makes perfect sense. a DP not working will prevent the third monitor from working, this is due to the passive adapter not converting DP signals into HDMI.

Although, the passive adapter works if it is just my main monitor and it. I assume its just for the 3rd and above monitors that need active?

if it were passive and it works, then it is active. A passive cable does not work at all, no matter the amount of screens.
