First is Resolution. Resolution is the number of PIXELS projected on the screen. Here bigger is better. The higher the resolution, the detailed information you will be able to show your audience. Computer and projector feature many different resolutions. But there are four that are the most common.
First is 800×600 pixels or SVGA Resolution and this is the minimum Resolution normally found in the business projectors. Then there is 1024×768 or XGA Resolution. It has higher resolution and its sharper and SVGA image. Both SVGA and XGA projectors project the 4:3 aspect ratio or moreover square shaped image. It’s sometime refer to as a standard screen size.

1280×800 pixels or WXGA Resolution is High Definition (HD) and its 16:10 aspect ratio or moreover a rectangle shape. The 16:10 aspect ratio is true widescreen and provides 30% more image area and a standard 4:3 image. 16:10 is also the most common aspect ratio for new computer monitors. With WXGA you can project the 780p HD image properly.

At the top of the range, it is 1920×1200 pixels or WUXGA Resolution. This is also a widescreen Resolution and can project true 1080p Full HD images.


Now after you find the ideal resolution and decide on widescreen or standard screen size, it’s time to choose the right brightness level which is used to measure in Lumens. Now the amount of brightness you actually need is determined by the room you are projecting.

For projector use in classrooms and conference rooms or rooms with outside windows, always choose a projector with a minimum of 2500 Lumens.

For home cinema projectors appropriate for theatre minimum you require around 1500 Lumens. However it is important to mention that Lumens or brightness is usually only a measurement of white light. It tells you nothing about the brightness of colors.

Fortunately several major projectors manufacture has recently introduced the new metric called “Color Light Output”. Color Light Output provides valuable information about the projector’s ability to deliver bright colors which are critical for projecting photographs, videos and other colorful graphics. If you want projector for projecting images with color look for a projector with high color light output. Ideally the brightness of color should equal to the brightness of light.
