Your computer monitor has great resolution; data projectors and television screens do not. Most every type of font shown on a computer screen looks great. When it is sent to a presentation device, the detail is lost. Serif type, such as Times Roman, has thick and thin lines making up the letters. The thin parts will be hard to see when projected. Use sans serif type, such as Arial or Helvitica, for your font choice. Any font that uses a uniform size for all lines will be much easier for your audience to read.
