4 monitors, 3 for gaming, one for web/applications

post #1 of 8
Thread Starter 
So I am hopping this will work. Can I have 3 monitors set up in nvidia surround so I can game at 5760x1080, and a 4th monitor as well? I've gotten used to, and don't want to give up, being able to have a game open one one monitor and work/movie/web/ect on my second monitor.

I've been planning on going to nvidia surround for gaming in high res, but just thought of this which could be a snag for me... Any help would be appreciated.

When a Nvidia graphics subsystem is setup for Nvidia Surround, only 3 monitors are supported.  So, you need another graphic card to support the fourth (and fifth) monitor/TV.  That additionaly GPU can be just a cheap and less powerful one.  Even an onboard Nvidia graphic chipset might possibly do (depending on the motherboard functionality).

Awesome, thanks for the info. I quess I will pop in my old 8800 and look into getting something low power to replace it. Maybe a cheap 210... Thanks again!

Ran into a new problem, I'll explain and hope someone has a fix.

I got my two new monitors, a third 24" and a 17", and a 8400GS PCI card. First thing I did was try out the new 24", so I plugged it in and it ran perfectly. It was real easy to set it to nvidia surround in the nvidia control panel. I then powered down, installed the new 8400GS, plugged the 17" to it, and turned the system back on. All four monitors came on, but they came on as individual screens, so surround was disabled after I installed the 8400GS.

I reinstalled the latest nvidia drivers (295.72 I think) and opened the nvidia control panel. Went to the sli configuration, selected "Span displays with Surround" hit configure and got a blank window...

Is there something I am missing? I took the 8400GS back out and running fine in surround again...

I installed the 8400GS again, just to see. Now Surround works on the 3 24" monitors, but I get nothing on my 17".

It seems that you only need to re-enable that 4th monitor under ''Set up multiple displays''.

(If this does not work, then try to disable the 4th monitor before you enable the Surround.  Then, re-enable it afterward.)

 

Off topic:- I suggest you to choose 'Auto-select (recommended)' under Physx settings.  Using your CPU to do Physx is usually not a good idea.

A better alternative is:- assign Physx to the GTX470 card that has lower temperature.  This usually means the bottom card as it has better intake airflow.  This offloading the Physx work from the top card to the bottom card might help to reduce the workload of the top card, thus lowering its load temp to help balancing the temp between the 2 cards.  Of course, this benefit only happens when you play a game with Physx.

Thanks a bunch, worked perfectly. Unfortunately I am back to the other problem now. This is really turning out to be a pain in the ass...

When SLI is disabled and all four monitors are active (as shown in the pic above), do all four monitors work perfectly?

 

From reading posts in a few forums, it seems that it has something to do with the order of installation of the hardware/software and the order of enabling.

So, perhaps you can use a little patience and try various ordering.  As Nvidia says it works, it certainly should, at least ideally.  But this is no guarantee as, you know, computers have a mind of their own.  Sometimes it works (for some people) and sometimes it just does not work for no apparent reason.

 

For example, below is a guy with GTX470 SLI (driving three monitors) and a GT430 (driving a 4th monitor/TV).  Check out his order in post #9.  Mimic that to see if it works for you.

And, you may also try to post your problem to WideScreenGamingForum where there is a section for multi-monitor gaming.  I suppose the people there have more experience with multi-monitor setup.
