There are many different kinds of projectors and knowing the difference between them is very important. Going on sites such as Amazon and Ebay pushes the cheap led projectors that just wont cut it with trying to project on an entire house. Sticking with name brands such as Epson, Viewsonic, Panasonic, BenQ, Optoma etc. is very important so the video shows up clear, nice, and bright on the house.
Next we am going to go over a few of the important features that must be looked at before the purchase of a projector.
One of the most important features is how bright the video projects on your house. The more lumens the better! We typically never recommend anything below 3,000 ANSI lumens. With that being said it is extremely important to understand that there is a huge difference between lux and ansi lumens. A 6,000 LUX lumen projector is equivalent to at best a 2,000 ANSI lumen projector. Sticking to the recommended manufactures we listed above is how you know the projector is ANSI lumens.
Short throw vs standard throw
Short throw projectors is what we recommend every time because most yards aren't large enough to use a standard throw projector. Throw ratio is how big the projected video/image will be based on how far back your projector is from the house. Most short throw projectors have a throw ratio of about .5:1. That means for every 6 inches of distance the video/image will be about 1 foot wide. So that means placing your projector 30 feet back will get your video/image about 60 feet wide. Typically that is more than enough distance so make sure your front yard is deep enough to place the projector in it without having to get to close to the street.
We will typically always recommend a HD 1080p projector. Of course the more pixels the better and clearer the image. Going with a projector less that 1080p (1920x1080) will absolutely work but expect the pixels to be more obvious.
All these features listed above are very important to take into consideration when buying a projector.
