WS10 [Before sale] Ultrawide screen and Windows 8.1

Hello,

I own WS9. I installed the latest version 9.0.3 to install VM Windows 8.1 and Windows Server 2012 R2.

I have an issue with display.

I use 3 full HD Screen linked width NVidia Surround Mode with 2 GTX590 Graphic adapter linked in SLI Mode.

With all previous versions of windows ans open suze, I use a 5760x1080 screen.

With my Windows 2012R2 ans Windows 8.1 it stay black in this resolution.

My quesiton are :

1. If I upgrade My WS 9 to 10, do you think the 5760x1080 resolution will work ?

1. Can I test WS 10 without licence, just to verify it works ?

Thanks for your answers,

Best regards,

Laurent
