Why do yours?
You can get a new projector and you quickly realize that their use against a white wall or hang a sheet of white cloth, gives disappointing results. Most options are intended for audiophiles with deep pockets who are looking for a definitive solution to home entertainment, and requires custom installation, and so forth.
There are less expensive, prefabricated office, the type (around $ 300), but the look and size may not be appropriate for your space. You can get a special paint to put on the wall, but he also had a role to convince the wife that a big white spot on the wall is necessary. What is really at their shoes.
How to Do It
Start with a piece of black cloth, with about three meters by two in a fabric store. For the mechanism of roll-down, take a length of white PVC channel drain hose (approximately 10 cm in diameter, so be quick to roll up), wrap the fabric around them once and hand sewing the long length. You have to be adjusted along the tube to stop the wrinkles, put the glue or tape hidden in each end to keep it. The fabric must be supported uniformly over the entire length of the upper part.
To this end, once you roll around a stick of wood and screws into the wall. The fabric is strong enough for you to leave the edges as they are. To keep it rolled up, fashion a wire coat hanger and sew a large loop at the top of the screen.
What to Watch
LCD or DLP
As with plasma versus LCD TV debate, the world of projectors, liquid crystal displays (LCD), competing for supremacy with Digital Light Processing (DLP) technology. DLP wins usually in terms of picture quality video, while LCDs run cooler and quieter – the fan noise and heat generated can be a big disadvantage compared to TV projectors.
Resolution
As in the case of flat screen televisions, high definition is becoming the entry level. Choose between 720p (1280 x 720) and 1080p (1920 x 1080) if you connect the game console like Xbox or playback of Blu-Ray. Resolution as a DVD quality (480p), it means you lose a faster, as the size of the projected image.
Brightness
The 'number of ANSI lumens "determines the way in which you see the images in bright light. Less than 1000 and, unless the curtains or wait for the night, darkens the picture too. Consider the primary use of the projector, and where they reside most of the time. Players will probably be more brilliant, while the projections for the late night in the dark, do not worry.
Aspect Ratio
For HD sources, such as game consoles and big screen broadcasts choose a native 16:9 aspect ratio similar to HDTV. 4:3 projectors can also be adapted for widescreen.
Lamp
Projection lamps most have an average life (the period before burning bright half) between 2000 and 4000 hours. Replacement prices vary widely, but is in the hundreds-of-dollars category. Consider this cost if the projector is to replace your TV.
Contrast
Some projectors are already high at the start, with contrast ratios of 75 000:1, televisions today can not even hope to match. Figures can be manipulated, but usually the higher the better.
