Ultra-Short Throw Home Theater

Evan Powell, March 14, 2017

ViewSonic's new PX800HD creates a HUGE image for an ultra short throw home theater projector. Placed just under the screen it will throw a 150" diagonal 16:9 picture from just 30". Its 2000 lumen light engine is sufficient for a 150" picture in a dark home theater. Or, if you normally want some ambient light in the room for TV and other entertainment purposes, you can cut the picture size from 150" down to 100" or 120", and add ViewSonic's BrilliantColorPanel ambient light rejection screens to make the picture pop like a huge flat screen TV.

The ViewSonic PX800HD is designed for large screen home theater with screen sizes in the range of 130" to 150" diagonal, and viewing in the dark. Its ultra-short throw design makes it easy to set up with the unit just under the screen, but you can ceiling mount it over the screen if you wish.

If you plan to have some light in the room while watching your big screen set up, you can reduce screen size and add an ambient light rejection (ALR) screen. Most ALR screens do not work with ultra-short throw projectors, but Viewsonic's BrilliantColorPanel (BCP) screen is made specifically for this purpose. The BCP100 is 100" diagonal and the BCP120 is 120" diagonal. Either one gives you excellent contrast and pop, making it look like you've got a huge flat panel TV. Keep in mind that a 100" diagonal screen is more than double the size of a 70" TV in total square footage, and a 120" screen is more than 3 times as large. So for the truly immersive home theater experience, this is the way to go.

Two things to be aware of with all ultra short throw projectors. First, the screen must be perfectly flat and uniform to avoid image distortion. Pop up screens are often not ideal for this type of use. We would go with a fixed frame screen, or a premium electric tab-tension screen that can reliably hold the screen surface in its ideal position.

Second, since ultra short throw projectors lack a zoom lens, image size is adjusted by moving the projector closer to or farther from the screen. There must be precise orientation of the projector with the screen, especially with screens of this size, so the PX800HD should be installed for permanent placement rather than used as a portable device.

If you are interested in a combination of the PX800HD and either the BCP100 or BCP120 screen, or if you want a larger 150" rigid frame screen for a more traditional home theater experience, call the Pro-AV authorized Viewsonic dealers shown below to ask about a package deal. You can't get package deals on Amazon, and the specialized Pro AV dealers can often offer a better price and better service when you are buying projectors and screens together.

How does this thing compare to the LS820 from the same Company - except the obvious differences (lumens and laser)?
