Hi Guys

 

One thing I was not sure of, as I never really use NVidea cards at all, but threw one into my second identical rig, but I have 3 x 19" screens plugged into it, but it keeps doing this:

 

 

 

 

Can the GTX670 actually cope with 3 x 19" screens via DVI or am I just pushing it too far running it in 4000 x 768 resolution?

It will do this a lot and then when flying, it gets so bad all screens go black, and thats it. This is running the latest NVidea drivers too, but it still did it a little using the previous drivers.

 

My ATI6990 runs 3 bigger screens at much higher resolution, and always seems to have the second GPU idle doing nothing, so I figured this card would be awesome for these smaller screens at that slightly lesser resolution.

Bump anybody?

I found the 670 a bit dissapointing as well

 

although i run 3 screens, they are not in surround because one is only 1900x1080 whlie 2 are 1900x1200

I run two 20" LED's in Eyefinity , 3200x900. That card should support surround. You may need to set a group resolution in Nvidia control panel and also set the resolution in FSX and set Widescreen to true in FSX.cfg. Hope this helps.

It should handle your screens easily. I have one of the first GTX680s and have three 24" ASUS widescreens. Resolution in both Win7 and FSX is 5970 x 1280 (I think it's 1280) and fps usually around 27-29. Supposedly, the best performance needsw both Windows and FSX set to the same resolution.

Do you have artifacts and color run all the time with FSX? Is it only with FSX? If it isn't a cooling problem then your best bet is to go here:

Also read through NickN's tutorial about setting up FSX for the best performance. He is more knowledgeabe about Nvidia/FSX than anyone have ever found on the net.

Good luck

It was doing this to me in windows too, but crashed out when I tried to load FSX and fly...

I thought maybe I was pushing the card too hard?

 

Its used in a really cold place.. So cold that the overclocked CPU @ 4.8GHz runs at 25deg on air cooling using an H100, so I know cooling isnt a problem..

 

It wasnt too bad on the stock drivers from the CD, but then I installed the latest drivers and it got so much worse.. I'm at a bit of a loss as to what to do about it.

 

The PC is an exact clone of my own rig, except for the graphics card..

 

I tried this rig out on a single projector in VGA mode and it did similar things too..

I have 3 X 24" in surround and I have no issues.. In fact I am using 4 monitors G670 FTW Card. Dbl check to make sure you did a clean install of the driver and the video card is not mal functioning.

All monitors must be working at the same resolution, refresh rate and sync polarity. Yours aren't, so it isn't noting strange that Nvidia 2D surround mode isn't working properly in your case. Look at this thread for more info: http://forum.avsim.n...e-screen-setup/

It should be working without any problems if your monitors match to Nvidia 2D surrond requirements.

 

Are you sure that all these monitors are working with the same: resolution, refresh rate and sync polarity?

If these are the same model, did you buy all together in the same time? Some producers are changing specification during time even for the same model. It is rare but possible.

 

Next thing, how are these monitors connected to graphics card?

3 x 19" screens via DVI

As said, all 3 are on DVI cables.

2 are DVI straight into the card, and 1 is DVI > DP converter..

 

All 3 screens are identical, even the serial numbers are very close together, numbers wise.. All 3 came at the same time.

 

No AV on that PC either, its a totally dedicated FSX box, only has FSX and Ground Environment Extreme on it since installing FSX+Acceleration, but even when not running FSX, this happens, but it recovers itself when FSX isn't running. I get that little error message in the corner saying it crashed, but has recovered.. That's why I updated the drivers, which is when it got worse.

 

I am using 4 monitors G670 FTW Card

Is your the GTX670 or is that some variant of it?

Probably problem is made by DP > DVI conversion. Do you know that DisplayPort signals aren't compatible with DVI? Converters are capable to match these standards and signals but may cause side effects. It doesn't have to be a problem when you drive your monitors independently in extended desktop mode but "span" mode (2D surround) requires all three monitors getting identical signals - conversion DP > DVI may be changing that. You wouldn't have such problem if you used monitor equiped with DP connector.

What you may do - forget of using DP output and use HDMI with HDMI > DVI cable. HDMI is backward-compatible with DVI (single-link) and no signal conversion is required - so it should be working properly.

Happens when using single DVI-I > VGA too with no other connections, but nowhere near as bad or as often..

Happens when using single DVI-I > VGA too

 

With DVI-I > VGA connection it is normal symptom. If you want to use digital monitor with analog signal you need to make adjustments. Some monitors has auto adjustments mode some has also user controlled. It is always described, how to make that, in monitor's manual.

After reading that I'm nearly sure that source of your problem with three monitors configuration is DP > DVI conversion.

I have 3 X 24" in surround and I have no issues..

 

Hello Manny,

 

Do you not get the spinning cursor and distorted popups when you use SHIFT+1, SHIFT+2 etc in Nvidia surround. That produces problems for a lot of people. How do you manage to avoid it?

 

Just, by the way, George Trovato has a workaround for the problem for the default planes - available as a download here. Otherwise his fix has to be applied to each plane individually.

Yes I do...But now I have kind of figured out a way to solve this for the most part. Its not a perfect solution but so far I am good.

 

I hope addon vendors test their stuff on triple monitor surround setup before releasing their product..for its not very complicated to fix. More and more people on the account of the GTX6xx cards are going for Surround view.

 

For all PMDG aircrafts, send an e-mail to PMDG Customer support. They would email you panel.cfg files for all their aicrafts.

 

For the F1 MD80 I posted my fix on the MD80 forum.

 

 

Generally you need to make sure that every Windowxx section including VCcockpitxx section in the panel.cfg has a Window size parameter.

 

window_size= 0.333, 0.874

 

That should fix it... for the most part. But that could distort the size of you pop ups...but you can either readjust it and save your flight or just try changing the individual size of the pop ups in the panel config.

 

 

 

For the new Airbus X Extended I commented out all the Windows panel except for Window00 and Window06=Left MCDU.

 

And resized the MCDU

 

 

 

[Window06]

file=MCDUIMG.bmp

Background_color=0,0,0

size_mm=430,726

window_size_ratio=0.250

position=7

//window_size= 0.350, 0.750

//window_size= 0.333, 0.874

window_size= 0.100, 0.700

//window_pos= 0.650, 0.140

window_pos= 0.850, 0.140

sizeable=1
