Multiple monitor usage for ancilliary displays using multiple GPU's

[lesthegrngo]

Hi all, I am using one large widescreen monitor for the main game screen, and then have four small lower resolution (10 inch or 7 inch) LCD monitors that are used for the MFCD's, artificial horizon and RWR.

 

The GPU's are a 1070 and a 1060.  Am I right in thinking the best way to hook these up is to run the main widescreen monitor off the 1070, and the other four off the 1060?

 

Cheers

Hi Les,

 

I'd say it depends on the amount of graphic memory.

The "main screen" will probably bring better results on that GPU with more memory.

Thanks Vinc

 

The main monitor is 2560 x 1080, and the 1070 has 8Gb  

 

The smaller monitors are all 1024 x 600, although two are porttrait, with the 1060 having 3Gb, but the level of detail on the lower monitors is relatively low. I can even set them as lower resolution I suppose

Cheers

Never tried that configuration,  but I suspect it will run at the speed of the weakest link/slowest card regardless of what monitor connected to what card. The reason I say this is that DCS treats screen real estate as a whole and only than you slice the combined res into view ports. Having a single card probably will be preferable. 

 

Good luck

Fair point; unfortunately I have a total of 5 monitors and the 1070 only has four outputs, so not sure how I will escape that.

That looked good until I realised it only clones the display! Thanks for looking though, appreciate the help and thought.

 

If that is not possible, is it then possible to have a slave PC attached, connected over a network that I can output data to with its own GPU and decouple it?

This is not display cloning

[lesthegrngo]

Ok, if it doesn't just clone that's great - on the description it said this

 

"Supports to implement the synchronization and extend display. Could connect with two external monitors at a time. Please note that the image on the two external monitors will be the same."

 

Looks like a neat solution then!

 

Thanks

The image will be cloned if you connect two monitors to the HDMI and VGA outputs of this device.

[lesthegrngo]

Thanks

 

So do you find it changes the FPS of the main monitor or is it completely independent?

This device does not load the video card, but the processor. I do not know how much it will affect FPS, until I tested it.

I tried one of those cheap USB to HDMI adapters and they seemed to work first.

But they did not rotate the display into portrait mode.

It's strange and the internet community blame Win10 for that behavior.

So maybe you have to try several devices to get the desired results.

It is my understanding that AMD had a crossfirex brand that allows you to tie two graphics cards together and improve the performance.  I am assuming that means combining the gddr capability,  but not positive.  I know they stopped that brand in 2017, and it only supports up to directx 11, but their software a,lows 6ku to manage the displays yourself.  Their replacement for the crossfirex does support directx 12, but they left the  software management to the game developers which it sounds like the DCS team did not do.
