Another Radeon R9 390 Multi (4+) Monitor Support question

Good evening

I have an ASUS R9 390 "STRIX-R9390-DC3OC-8GD5-GAMING" card, Gigabyte

I have 3 24" monitors 2 x Asus + a Acer connected to the video car. I also have a 37" LG TV connected to the PV via DP port.

Before the tripple setup., I used to be able to have the TV display as an additional monitor. Right now I have the 3 monitors connected thru HDMI, DVI and DP port plus the TV in the DP port.

I can have either the LG by itself, 2 x 24" monitors plus the LG but always the 4th monitor goes disabled, I have created a triple profile in Eyefinity and trying to add a +1 (LG tv) but since I can not activate the LG tv I can add it.

Is there a trick to this? I have swap cables and have asked for assistance to ASUS but all I get is links to AMD's old and new pages mentioning the old CCC panel.

Re: Another Radeon R9 390 Multi (4+) Monitor Support question

How is each display connected to the GPU and are you using any adapters or Dongles?

The 390 can support a maximum of two passive display connections and the third monitor and beyond must use a native displayport connection, or a displayport connection to an active hdmi/dvi adapter.

morning

Currently, the monitors are connected thru DVI, regular cable; HDMI, regular cable; DP port with an (I think ) Active adapter. The TV is connected using the same DP adapter.

The monitors are discovered as 1;2;3.

As long as I delete one of the monitors the TV can be added.

The DP adapters are the Kensington adapters K33984WW.

Thank you

Does the adapters have the word ACTIVE written on them? I'm not able to determine if that is an active adapter or not as it is not mentioned on the Kensington website.

With all displays connected, please can you attach (do not copy and paste it) your DXDIAG report to your response?

This is an active adapter.

Good morning

Thank you for your info, turns out the adapters were not Active. So I order a new set.

My question now is,Do all the DP ports have to use Active adapters? Or would I needed it for the TV only.

Thank you

As per my post above, only two passive display connections can be supported at one time. You'll need two active adapters.
