I get an error when I enable more then one connected LCD -- "Invalid Hardware or Driver Detected" 

 

Prepar3D was unable to initialize the renderering system and will shut down. 

 

Does anyone know a work around? I am using the other LCD for panels and not to extend the cockpit view.

 

Thanks. 

Bumped -- help? I am using a Nvidia 660ti OC.

Sorry no help here... Works fine on three monitors for me. Have you updated your drivers? Worth a try...

Are you running from more than one grafix card? P3D will not start even if the main card is DX11 compatible Try disabling the second screen from the display options. Use only the DX11 card. Its annoying, I don't want to use P3D on the second display but would like to have it available for other things

Yes, one LCD is outputing from the built in 'intel' graphics card - so no DX11 support there. There is no way around this? FSX worked fine. I am only running Prepar3d on the nvidia GPU -- would like to use an external program (prosim737) for the panels.

I hope they fix this because its a major issue for some people. I wonder if there is some sort of work around, there must be something in the start up that checks the cards compatibility, if this can be disabled we might be able to use our "lowly" second cards for prosim or in my case flightsim commander

Why aren't you using one of the ports on the Nvidia 660ti card for your second monitor?

Because one of the LCD is a old 15" and only has a VGA output. The nvidia 660 ti has none -- I'll have to buy an adaptor to be able to plug it in.

Those adaptors are pretty cheep, even in Australia. 

 

What motherboard do you have?

 

gb.

This could be a bit awkward but have tried disabling the monitor connected to the motherboard

in Device Manager then starting P3D then re-enabling the monitor after P3D has started?

^ This They're like $1.50 on monoprice.. I have about 4 of them in my "Old technology and electronics I will never use but my tech OCD disallows me to throw away old electronics" drawer  They're underneath an old 8800GT, cell phone and two power cords.

I have a Asus Z68 motherboard. Yes, disabling then renabling them after starting P3D works. I can buy an adapter, but then I am now stuck with 2 useless built in motherboard outputs (the VGA and DVI) -- I would have liked to use that for some future accessories - e.g. a CDU which requires a VGA output.

Yes agree it is frustrating.

Is this P3DV2?

I would head over to P3D forums and see if they have an answer.

That 660ti does have extra hdmi and displayport outputs.

You could get a VGA adaptor for those.

I've bought a 2 dollar adaptor. Hopefully this will do for now. I hope to eventually add 2 projectors, a cdu and 2 more displays for panels - running out of ports

 

Perhaps I need to invest in a cheap steam machine for prosim737
