Gday.

From what I gather from the video, you have to connect to the DVI sockets on all the monitors. You need a passive HDMI to DVI adaptor.

to be honest then i don't think it's a plex card and won't work in windows with 3 monitors connected.

 

i don't fully understand how graphics card work but put simply each connection needs it's own clock to sync/time the data sent to a monitor, most cards only have 2 clocks so therefore can only display to 2 monitors in windows, a display port allows windows to share 1 clock for more than 1 monitor, and i think linux must also be able to share 1 clock to more than 1 display (as long as they are identical.) using a software solution instead of windows hardware solution and why 3 monitors work in linux but not in windows.

 

i think a sapphire plex card has an extra clock built into it and why that type of card is capable of displaying to 3 monitors without the usual needed display port.

 

one last thing in windows 7 in catalyst on the left there's an amd eyeinfinity tab, did you click on that and try to build a 3 monitor setup?

Display Group just show ( 2x1 ) don't find out ( 3x1 ) 

[terry1966]

well it looks like iammy was correct with his first post/assessment then and it is not possible with that card to run 3 monitors in windows and you need a sapphire flex card with 3 digital outputs (no vga output) or a card with a display port even though in linux your card will run 3 monitors perfectly.

 

sorry really can't think of anything else for you to try in the off chance it will work with 3 monitors in windows.

It is possible with a active VGA to DVI Adapter.

yes it is, but your monitors do not have DVI input.

You can try this cable setup so the video card is delivering the right signal to each monitor port,, if it does not work, as terry said, you will need a more capable card.

This is a single link DVI to HDMI Cable. 

My current cable dual Link DVI to HDMI cable. 

 

could  It  be a reason ?

[iammykyl]

I don't think so.

The socket on your GPU is DVI-D Duel Link.

  

The signal speed it outputs is in two halves, your Dell monitor will only require max of 4.95 Gbps, so will only use half of the bandwith signal.

Providing the cable you have is HDMI male to DVI-D male, it will work at socket #2.   DVD-D/male--cable---HDMI/male.

You will need #2.   HDMI/male---cable/--- HDMI/male  (reply 23) 

 

This is just surmising as I can't be sure.

 

The VGA clock is not shared.

Either the HDMI or DVI-D clocks are shared if Flex is present on the video card.  To test.

Set the VGA monitor as primary.

enable the HDMI monitor second then see if the DVI-D monitor will span, if not, I can only suggest trying in every combination possible.

As you know through Linux, all the video ports work, if you can't span all monitors under Windows, I don't think the card is Flex enabled, or it is faulty.

Buying/trying any type of active adaptors would be wasteful, you should look at a more modern card.

 

Good luck.

if i was to try i'd get an hdmi to active display port adaptor, use the hdmi out convert it to displayport then convert connection back to hdmi onto monitor.

pc - hdmi - displayport - hdmi - monitor

 

adaptor :- https://www.amazon.c... to displayport

display port to hdmi cable :- https://www.amazon.c...t to hdmi cable

 

not sure it will work but think it should because the timing is handled by the displayport adaptor, personally though it might be cheaper just to add a second card or buy a newer card with display port anyway.

Gday.

Did you get the 3 monitor display sorted?   An update would be very welcome.

 

Thanks.
