• The Dell 1800 is a digital projector that you can use to display video from your DVD player or computer. Instead of watching videos on a big-screen TV, you can project images from the Dell 1800 onto a screen as large as 304.9 inches (measured diagonally). To save energy, you can set it to run at a lower power level, which will also increase the projector bulb life.
  
  

Light Valve

• The Dell 1800 projector's light valve technology uses a 0.55-inch, XGA DDR chip, enabling it to project bright, clear digital images onto a screen located up to 39.4 feet away.
  
  

Brightness

• The maximum brightness of the Dell 1800 projector is 2,100 ANSI lumens. Under normal use, the projector uses 225 watts. You can set it to "Eco" mode to run at 190 watts, which is slightly dimmer but can give the lamp a longer life.
  
  

Contrast

• The Dell 1800 projector's contrast ratio is 2,000:1. You can adjust the contrast to control how much of a difference there is between the brightest and darkest parts of the image, and the amount of black and white in the image.
  
  

Lamp

• A 200-watt, 2,500-hour bulb is used in the Dell 1800 projector. The bulb will last up to 3,000 hours if the projector is run in "Eco" mode, and it is user-replaceable. If the projector overheats, a "Temp" warning light will turn on and remain solid, and the display will automatically shut down. A blinking orange "Temp" light indicates that overheating was caused by a failed projector fan.
  
  

Pixels and Color

• The Dell 1800 projector has a resolution of 1024 by 768 pixels and displays 16.7 million colors, enabling it to show detailed, vivid video images.
  
  

Lens

• The Dell 1800's projection lens is F/2.35-2.47, f=21.83-23.81 mm with 1.1 manual zoom. You can use this to adjust the size of the projected image to fit on your screen.
  
  

Video Compatibility

• The Dell 1800 projector is compatible with NTSC 3.58 and 4.43, PAL, PAL-M, PAL-N, SECAM and HDTV television systems, enabling it to project images from DVD players, as well as video signals from your computer.
  
  

Projection Screen Size

• The projection screen size of the Dell 1800 projector ranges from 34.7 to 304.9 inches, measured diagonally.
  
  

Focus

• The Dell 1800 projector has a manual focus ring, which you rotate until the image is clear. It can focus its images onto a projection screen at distances from 4.9 feet to 39.4 feet.
