CRT Refresh Rate & Color Depth

This lesson covers Refresh Rate, Color Depth and how they work on a CRT Monitor. The Refresh Rate is the amount of time the electrons sweep across the display screen to redraw (updates) the screens content. We’ll demonstrate how that works and explain the calculations for it.  For example, the refresh rate is measured in hertz with settings as low as 60 refreshes per second. Ideally we’d want at setting of 75+ refreshes per second or better, that rate is undetectable by the human eye, we can only see the resulting output if those results are different from the previous display.  You’ll learn why adjusting the refresh rate is important and why hazards can occur from settings that are too low or too high. You’ll learn based upon the CRT monitor size what your size to refresh adjustment rate should be and why, and how color depth can play a significant role in the level and quality of display output. We’ll explain what’s met by True Color, how you can determine what that is, explain what VGA means, and why color is also an important consideration for selection a monitor or CRT monitor in particular.
