I'm Jim & I am building a DYI Golf simulator in my home. My Graphics card is an Nvidia ver. 8.1.1940 and I would appreciate some
help on creating the correct Pixel combo for my new 4k projector (BenQ LU710 HD) that I could change to whenever I use the
projector for my simulator.

I realize this is a 'long-shot' request but thought it was worth a try. The screen size is 9' x 9' or 108" x 108". I believe 2160 pixels by
2160 is what I need to add which of course is "custom" and I've never done this before.

Appreciate any help or suggestions.
Thanks! jnu
