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

Both CRT(Cathode Ray Tube) and LCD(Liquid Crystal Display) monitors will have theirs specific refresh rates and resolution. LCD can be a multi touch monitor. But Degaussing is not a property of LCD monitor which is actually a method of erasing magnetic media and the removal of remnants of previously recorded signals by passing magnetic media through a magnet field more powerful than the media itself to rearrange the magnetic particles used in cathode ray tubes.

LCDs use Liquid Crystalls whose orientation is based on the heat/temperature as against CRT which are based on magnetic field. It takes a fair amount of heat to change a suitable substance from a solid into a liquid crystal, and it only takes a little more heat to turn that same liquid crystal into a real liquid. This explains why liquid crystals are very sensitive to temperature and why they are used to make thermometers and mood rings. It also explains why a laptop computer display may act funny in cold weather or during a hot day at the beach.

So option is D.
