DLP verses LCD


Welcome to Projector Tips

When selecting the correct projector for the classroom or even the office, there is that old question...DLP or LCD? Here are some helpful tips when making that decision.
LCD –
Advantages
• Richer color dynamics for better results in rooms with ample ambient light
• Draw less power
• Throw less heat
• No color filter wheel = No "rainbow effect"
• Slightly quieter Seemingly sharper image on data
• original technology
Disadvantages
• usually requires filters which should be cleaned according to manufactures requirements (usually 100 to 300 hours)
• More visible pixels
• Some screen door effect on certain video images
• Physically larger - Even for the same number of lumens
• Poorer contrast
• Blacks come out lighter gray than DLP projectors

DLP –
Advantages
• Smoother video
• Smaller box
• Pixels far less visible, (although normally not an issue for business use)
• More “filmlike” on DVD and HDTV
• Generate "blacker" blacks
• Higher contrast
• Filter- Free
• Great for multimedia
Disadvantages
• Rainbow effect bothers some
• More moving parts (color filter wheel)
• Color filter wheel often produces soft but audible whine
• Poorer reds and yellows at full power
• Color saturation
• Need more lumens than LCD, for rich colors, when dealing with ambient light
The final judgment should be your eyes. Lining up different models and showing the same image and text with the exact settings should be the final test. Also use the following web site to run tests with each projector.
