Hi, I have a 120 inch 16:9 huge screen, which I use at my home theatre room and we watch all Blu-Ray movies at 16:9 wide screen. At that time, the projector source is my Blu-Ray Player and amplifier through HDMI. I want do project the same 16:9 widescreen way from my Windows 8 PC. How do we do that ? As soon as I connect my PC and projector through a RGB cable, the screen resolution of the PC changes to square 4:3 resolution. Why is that ? And on the projector screen, then wide view is totally gone and I see the squarish view 4:3 view ? How do I get the complete 16:9 output to projector screen from a PC ? I also tried through HDMI and my Apple Macbook Retina, I still dont get the wide view.
