If you want your audience to sit, listen, and watch your presentation without interruptions the television display is a good choice. People are comfortable being passive while watching the tube. The television also provides excellent color saturation and clear, crisp graphics and animation. Large monitors are easy to see in brightly lit rooms without dimming the lights. Television monitors have several shortcomings.
Most people underestimate the size of the monitor required.
To be seen clearly, very large monitors are required, even for small rooms. Most television monitors are useless in large classrooms. Another problem is that text is hard to read on a monitor. This limits your font choices to large sans-serif fonts. The inexpensive models limit your presentation to fewer color choices and lower resolutions.
