Problem enabling 3 displays simultaneously. Solved

Question

Hello,

I just bought my 3rd monitor and all my problems started. I’ve already browsed most of the topics addressing my issue and they all ended up archived without an answer.

First of all, my setup:

ATI Radeon HD 6970 Dual Fan 2GB
2 iiyama ProLite B2480HS monitors
1 iiyama ProLite B2409HDS monitor

I connected my monitors as follows:

2 iiyama ProLite B2480HS connected to my DVI ports
1 iiyama ProLite B2409HDS connected via HDMI (monitor side) converted to MiniDisplayPort to be connected to the graphics card.
The adapter in question: https://www.ldlc.com/fiche/PB00090878.html

My problem:
I can activate 2 monitors simultaneously but not 3. Catalyst Control Center shows this: [image]
It is the same when I try to enable Eyefinity; it will only use 2 of 3 monitors.

How can I fix this problem? I’m waiting for your response with anticipation.

Regards.

Hello. ATI Radeon HD 6970. Make your life easier with Sapphire FleX technology Eyefinity opened up new gaming possibilities thanks to extended display across three screens, but without DisplayPort screens its setup can still be somewhat complex. Sapphire FleX technology simplifies deploying a multi-screen solution by allowing easy connection of three DVI monitors without having to invest in DisplayPort screens or additional active adapters. This technology will even allow you to support up to 4 screens, this time with the use of a DisplayPort monitor or an active adapter.  So that means your screens aren’t properly connected. Who loves instruction! finds the knowledge that comes from reflection! PS. Create a restore point often! it resolves quite a few problems.

I’m going to try the technology you mentioned above and I’ll let you know how it goes.  EDIT: To use Sapphire’s FleX technology you need a dedicated graphics card :x  Regarding my problem, it’s still current; I also tried the 2 Mini-DisplayPort ports on my graphics card and it’s still not resolved.

Problem solved, an active MiniDP to DVI adapter was indeed needed for it to work.
