1080p Digital Projectors
Combine the two and the
result is a frame resolution of 1920×1080, or 2,073,600 total
pixels; a picture so stunningly realistic and clear it astounds
viewers. Users play movies or other media on computers or DVD
players connected to the projector, and the projector displays the
much larger image on a surface such as a wall or pull-down image
screen. Clean and crisp pictures are the main purpose for
purchasing and using an HD projector, and these projectors provide
users incredibly sharp, clear high-definition images when paired
with a 1080p source such as an HD DVD or Blu-ray disc. If the
source is non-HD or the projector is not HD capable, digital noise
will appear, and a soft, blurry image will result. The next
important feature in 1080p projectors is its de-interlacing
capability. This eliminates flickering and motion flaws common in
less performing projectors. Lumen output is significant because the
higher the lumen output, the brighter the picture. This will be
very important to users who plan to utilize the projector in
well-lit conditions, and using projectors with insufficient lumen
output results in transparent and dull pictures. Contrast ratio
assesses the difference between bright colors and black; the
greater the gap between the two numbers the more noticeable the
disparity between the two on projected images, resulting in better
low-light images and vivacious colors. Black levels correspond to
how rich the blacks in images will be; projectors with low black
levels may appear as “bright blacks” or even grays. The item last
on the checklist for a great 1080p projector may seem superficial,
but can prove to be very distracting; a model with a quiet fan.
Projectors can become very hot, especially during prolonged use or
use under maximum settings, and a silent fan can make an incredible
difference; especially while watching a movie or using the
projector during a presentation or speech.
