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.
