As a matter fact setting up a home theater projection system for playing games or any other purpose is not a job for everybody and along with a lot of room these projectors also require controlled lighting and a few essential accessories those are also required to be purchased. But buying a projector can always be considered as a worthwhile investment.
Ambient lighting
As projectors use reflected light for displaying pictures they are made to compete with other lightings also present in the room and presence of even a small amount of ambient lighting can have drastic effect on the picture quality. Certainly there are high end projectors available those can better fight with the ambient lighting in your room than the other available models and give you excellent quality picture all the time. But if you planning to buy a cheaper and affordable product then ambient lighting are truly going to be a concern and that is the reason while buying a home theater projector – output brightness rating of the product must be checked out beforehand. Projectors with a minimum rating of 1700 ANSI lumens are found to be giving good quality pictures in spite of the presence of a small amount of ambient lighting. If you are looking for projectors capable of handling stronger ambient lights, products with lumens rating of 3000 and above are better choices.
Room size
As the required screen size for a projector is quite large they also require large rooms and while buying projectors always make sure that it has the ability of displaying both in normal and upside down modes. This will allow you some flexibility regarding the place where the projector should be mounted. Long rooms are always more suitable for installing a projector for this allow viewers to sit back as far as possible for minimizing screen blocking.
