AMD 7950 and eyefinity

[bigdave2k9]

This may sound like a daft question, but ive spent the past few hours looking at various sites and i keep seeing a different version of the 7950 i have?!

The 7950 i bought from OC has 2x DVI 1x HDMI and 1x DP

The pictures i keep seeing are showing, 1x DVI, 1x HDMI and 2x DP

Have they changed the card in some way or is there two variations to this card?

It depends on the manufacturer on what connections they place on the card, but Eyefinity still works the same. First two monitor connections needs to be DVI, HDMI or VGA, while the third+ needs to use Displayport.

The one i have, which is still different to the advertised image used.


How would i go about getting 4 monitors to link up to it?

As im getting 2 more monitors this week to have 3 horizontal next to each over on my desk, but i have my tv connected to it aswell....

Internet guides are not exactly detailed enough, there just like do this and this and it will work... which for me isnt helpful.

Might be a new revision of the card or something.

As for your card, unless your monitors support Displayport daisy-chaining, you're stuck to three monitors (TV to HDMI, monitor 1 to DVI, monitor 2 to Displayport. Second DVI will be disabled).

However, what's your PC specs? You could be able to use the onboard GPU for the 4th monitor.

bigdave, your card only supports three outputs, and 1 of them has to be DP. The others can be any combination of the remaining two ports. It's not unusual for manufacturers to revise cards - that seems to be a pretty big revision though.

However, your motherboard has integrated graphics, and supports up to 3 monitors (3 more monitors!). So if you activate onboard graphics, you can plug your TV into that. Of course, that means its driven by the integrated graphics, so gaming on it will be crap.

You have Lucid Virtu, I've never used that, but IIRC, it's supposed to allow you to allow your graphic card to drive a monitor connected to the integrated graphics port. Maybe someone else has experience with that, and can chip in.

 

[bigdave2k9]

This isn't quite accurate.
If you have 2 or less monitors, you may use any combination of connections (1 DVi + 1 DP, 2 DP, 1 HDMI + DVI, etc).
If you have 3 monitors, you need to use at least 1 Display Port; the other two can be any combination (including the other DP).
If you have 4 monitors (and your card supports it - most 6xxx cards do, 5xxx ones don't), you need to use all the connections obviously.

Direct from the AMD website, i would need to support the 4 monitors,

2x display port
2x DVI / HMDI

Which this card dosnt have...

Edit:
Would i be right in assuming, if i got a displayport 1.2 hub i could get the extra monitor on?

Surley your card has the ports you need for 4 monitors?

You have integrated graphics, if you're using the TV only to watch videos and stuff, the onboard Intel will be fine. The rest of the monitors can be used on the 7950 and in Eyefinity mode.

If you can find a good DP 1.2 hub, yes that will work.

4 connectors on the card but only the first two monitors can use DVI/VGA/HDMI. The third monitor and above must use the Displayport.

 

[Cleeecooo]

From what I understood, he wanted to run 4 monitors

 

[Orcvader]

He does, but while his 7950 has 4 physical connectors, only 3 will run together. The 4th monitor will be disabled by the card since it can't support it.

Displayport works differently from DVI/HDMI/VGA hence why it can support multiple DP monitors.

EDIT: Managed to find the pic:

This is me just being me, but i thought once you connected a graphics card the onboard is "disabled" and you just use the graphics card? Thats past experience, times change...

edit:
What would people recommend i use.. DVI/HDMI/DP or DVI/DVI/DP? Before you ask, the monitors in question are 3x Asus VS239HR 23" LED IPS Monitor

 

[Orcvader]

There should be an option to enable the onboard in the BIOS.

I'm using the 7950 for my main monitor and the onboard Intel for my second with no problems.

I have just set up eyefinity, using a 7950 with my tv also connected. As said above one monitor has to be disabled to run the TV. Not really a big deal is it? Are you going to game on eyefinity AND watch a movie at the same time?

I simply set up 3 presets in CCC with hotkeys.
1) Enables eyefinity + disconnects TV
2) Enables extended desktop + Disconnects TV
3) Disables 1 monitor and enables the TV for use.

Well that's weirde, you quoted part of my reply that I removed before I actually posted it!

I noticed you didn't have the layout to have 4 monitors, and amended my post (see post 6).

You might be able to run 4 monitors together, using 3 from the graphic card, and 1 from the onboard. Again, see post #6.

they have the info wrong on the OcUK site, there info / pics is the V1 where as OcUK are selling the V2 which has different ports and also has a shorter Cooler which was just as well for me as the V1 would not have fitted in my case.

I have submitted a customer note for them to hopefully update the page.
