Welcome back to another installment in our ongoing series on Projectors: Your Technical Questions Answered. In this segment, we’ll take a look at resolution: what it is, and how to choose it.
The term “resolution” simply refers to the number of lines of color display. The higher the number, the greater the resolution, and the crisper and more detailed the projected image. If you have a regular (not HD) television, there are 480 lines of resolution. A high-definition television (HDTV) has over 700 lines of display.
LCD projectors have fixed resolution, and we will take a look at each kind.
VGA
VGA stands for Video Graphics Array. This technology was first introduced in computer display monitors in the late 1980s and is now obsolete technology.
SVGA
SVGA stands for Super Video Graphics Array and this resolution is popular for its high quality and affordable price point. SVGA resolution specs are 800 x 600 pixels.
XGA
XGA stands for eXtended Graphics Array and has a fixed resolution of 1024 x 768, which is excellent quality.
SXGA
SXGA stands for Super eXtended Graphics Array, with a resolution of 1280 x 1024. This is rather expensive and therefore someone uncommon.
The thing to remember is that there is a difference between the projector’s resolution and what the LCD projector receives as its incoming signal. Therefore, a projector internally resizes the signal’s image (shrink or stretch) to adapt it to the projector’s fixed resolution.
