Although the cheaper the better. Is the HD65 a good option? The PJ will be about 11' from the screen, with me sitting 1' infront of and under the PJ. As im renting the flat, I can't ceiling mount anything so im considering a portable screen, and to place the projector on shelving to get it as heigh as possible. Im hoping to achieve a ~198cm x 118cm screen size. Is this possible or reasonable? Any other options worth considering?
