Projector Resolution and Contrast Selection

Resolution: the projection resolution can be selected according to the actual
projection content for deciding what grade of projector to buy. If the
demonstration content is dominated by general teaching and word processing, you
can select SVGA(800 600); if the demonstration of fine images (such as graphic
design), you can choose XGA(1024 768). Since the mainstream resolution of
laptop and desktop is to meet the XGA(1024 768) standard, it is recommended to
choose the projector with the XGA(1024 768) resolution if the budget allows.

No matter what kind of digital products, the resolution is everyone's concern
factor. Common resolutions and representations are as follows:

SVGA: common resolution for 800x600 budget projector

XGA: 1024x768 projector resolution for mainstream business and education
projectors

720p: 1280x720 or 1280x768 mid-range resolution for home projectors

1080p: 1920x1080 or 1920x1200 resolution for high-end home projectors

At present, the price of 4K is more expensive than market price. Therefore,
the general 800*600-1080p resolution of the projector in the office and home
use can according to the personal requirements and pursuit

Contrast is a concept that everyone is very familiar with. In daily photo
editing, it is estimated that contrast determines how many color levels an
image can recognize, and it is the key to see more details.

In addition, the contrast has a great impact on the imaging of the projector.
Usually, after the resolution reaches 1080p, the contrast has a greater impact
than the increase of the resolution. Most LCD projectors have a nominal
contrast of about 400:1(ANSI), while most DLP projectors have a nominal
contrast of more than 1500:1(all white/all black). The higher the contrast, the
higher the price of the projector, if only using the projector to demonstrate
text and black and white pictures, projectors whose contrast is about 400:1
projector can meet the needs, if it used to demonstrate colorful photos and
play video animation, the best choice is 1000:1 high contrast projector.
