Guidelines to Beginners Using Short Throw Projector

Before you begin, you need to decide whether you will be using your new projector for displaying pictures, playing video games, or giving demonstrations. This will affect how dark or bright your viewing room is and what resolutions you will need, and things like link choices. Also work out where you would like to set your projector relative to its display. To begin with, you will have to think about brightness and contrast. Most Projectors have their brightness mentioned in two ways, Lumens and foot-Lamberts. Sadly the Lumen rating is not a really useful indicator of brightness, as it frequently does not take into consideration the viewing size of the last picture or decrease due to normal instead of maximum usage. In dark conditions such as a dedicated home theatre room, start looking for a brightness rating of approximately 40 flu, and boost it based on how much additional ambient lighting your viewing room will have.

Next you need to think about the supported resolutions you want to display. The top is 1080p, so called Full HD, and will make it possible for you to exhibit Blue-Rays and other high-definition articles correctly. To get complete use of the display, make sure it is resolution matches that of your projector. Contrast is often a more useful measure of projector quality than brightness. A high quality projector will have a contrast ratio of 5,000:1 or longer, all though check to find out if the projector uses dynamic iris to help boost its comparison range.

These work by restricting the light output in dark scenes, allowing the projector to create blacker blacks. Some best short throw projector will also only quote on or off contrast that is the difference between a complete black and full white screen. A better measure is ANSI contrast, which utilizes a chequered test routine, and measures the difference between the dark and light squares. This value will be untouched by any dynamic iris, and is normally a lower value.

Finally, make note of this throw distance of the projector. Short throw projectors are intended to be placed closer to the screen and still produce a major picture, whereas long throw projectors are the contrary. Also quoted are the quantities of zoom available, which will permit you to grow or shrink the picture somewhat. Another helpful feature on many projectors is lens-shift. This will allow you more flexibility in placing the projector relative to the display by permitting you to move the picture up and down or left and right by a certain amount without distorting the picture.
