Just moved my projector to a new position and I am using the zoom and lens shift to fill the screen. But when I zoom to fill the vertical, the sides are not filled in and if I zoom a bit further, the vertical is too high. I am just trying to perfectly fill the 16:9 beamax projector screen (up to the black surround). What is this problem called if it has a name and how do I fix it ? Any suggestion are welcome ! My PC is set to 1280 x 720. The Sanyo Z3 projector is also set up for this. I am using VGA out from PC. I am sure it is something simple. Hopefully it is nothing to do with the fact that the projector is off center, to the left and above the screen and I am using adjustments with lens shift. Thanks.
