The most important aspect of this process is having the right projector. The more lumens the better, but you should be using a projector that is no less than 4000 lumens. The sweet spot for price & brightness is around 4000-5000 lumens.  The contrast ratio is considered an important spec, but what’s probably just as important, or more important, is using a DLP projector. The blacks are deeper, making it so you don’t see the gray box. You will also want to pay attention to the native resolution of the projector. Full HD, 1920×1080, is preferred, but a projector with a native resolution of 1280×800 will project a nice image, too.

Projector features
Be sure the projector has both horizontal and vertical keystone correction–having both will allow you the most flexibility with where you place the projector and still have an image that looks as it was designed. Some projectors also have something called quick corners or corner fit, which also helps to adjust the image so it looks good when shooting from weird angles. In addition, it’s great if you can find a projector that can display images from a USB drive. If it doesn’t, you’ll need a media player.

The following are the minimum specs we would recommend when considering a projector:

Lumens (4000+): how bright the image will be
Contrast ratio (over 8,000:1): Difference between white & black. A contrast ratio of 8000:1 means the white is 8000 times brighter than the black. However, more important than contrast ratio is DLP over LCD.
Keystone (BOTH horizontal & vertical keystone): This is what allows you to shoot at angles, or different heights, and adjust the image so it doesn’t look distorted. 
– Resolution (at least 1280×800): The number of pixels. The higher the number, the more pixels are used, and the higher quality the image is.
Zoom (at least 1.3x): This is how much you can change the image size by adjusting the lens. This is what allows you to move the projector further away without the image being huge (or to put it closer and get it bigger).

Optoma WU465

Pros:
4800 lumens, 1920×1200 resolution, 4-corner correction, very good contrast ratio (20000:1), big zoom (1.5x), can display images from USB, USB can power media player, light weight.

Cons:
Can’t keystone with image displayed from USB (we recommend using a media player with this projector for easier keystoning)

BenQ MW732

Pros:
Very good contrast ratio (20,000:1), Horizontal & vertical keystone, 4 corner adjustment, Big zoom (1.3x)
Light (5 lbs)

Cons
Can’t display images from USB thumb drive (but you can use a media player to display images)

Epson POWERLITE 1940W

Pros:
4200 lumens, horizontal & vertical keystone, excellent corner correction, big zoom (1.6x), can display images from thumb drive.

Cons:
Big & heavy, LCD instead of DLP, low contrast ratio (but still not an issue getting rid of the box), resolution is good (1280×800) but full HD would be better, technically discontinued but brand new is still available.
