Ryan, you can easily mount the 6030UB 20 feet from the screen. How much light is lost in the zoom lens depends on the screen size. If your screen is 200" diagonal, you will be using the wide angle end of the lens and no light is lost. If you screen is 100" diagonal, you will need to use the telephoto end of the zoom. All long zoom lenses curtail light output as you move them toward the telephoto end of the range. On the 6030UB, you lose about 20% of the light at the zoom's mid-point, and 40% of the light at the maximum telephoto position. This is normal for a 2.1x lens.

Whether the light loss is an issue to worry about depends on your room's ambient light, screen type and size, and so on. If you were to use the calibrations we used in this test for Living Room mode, and also use the maximum telephoto end of the lens, you would net out 840 lumens. That is plenty bright for dark room theater on a 120" 1.3 gain screen.

HD 1080p resolution is very high resolution for video, but relatively low resolution compared to the precision of today's optics. The position of the zoom is not going to impact the perceived sharpness of the image.

The professional custom installers who sell the 6030UB can help you sort out these details better than we can in a blog post. We encourage you to give them a call and have a more detailed conversation about your installation.
