Hello,

John, thank you very much for all that information.

It will be great if you can share your testing results at full 4K
resolution.

Now I have a Suse 13.1 with
Quadro 2000D Workstation Graphics Card - 1024MB, GDDR5, PCI Express 2.0
x16, Dual DVI, DirectX 11, Single-Slot.

Do I need a different card to support 3D and 4K?
Is this LG 4K TV comes with HDMI 2.x input?

Thanks
Nikolai
