You have a customer who has bought his first computer in many years, including his first LCD monitor. He is having trouble finding and adjusting all of the available settings on the monitor, and you tell him that there are some features and properties of a CRT monitor that are not found on an LCD monitor. Of the following, which features and properties does an LCD monitor not possess?

A. Refresh rate

B. Resolution

C. Multi-monitor

D. Degauss

Solution

A and D. LCD monitors do not have a refresh rate as such because LCDs use a separate backlight for illuminating an image displayed by liquid crystal shutters and shutters do not “refresh” but rather stay continuously at their stated opacity. You only need to degauss a CRT monitor, since LCD monitors do not acquire or generate a magnetic field.
