The Do's and Don'ts for LCD Monitors

The Do's and Don'ts for LCD Monitors

Everyday, we turn our LCD monitors on and off without giving much consideration to them as anything other than common household or office products.

Since the servicing of display products has been the core business of Megatech for well over 20 years, I felt that it would be more than ideal to provide you with a general upkeep list of considerations when working with your LCD monitor:


  • ThermometerThe LCD monitor’s life can be shortened when it is used under conditions of high temperature and humidity.
  • When used at low temperatures of 10 degrees Celsius and below, response time and brightness are affected in such a way that the proper display may not be obtained.
  • When exposed to fluctuations in temperature (i.e., hot to cold, cold to hot), dew may be produced on the panel's surface which can affect operation of the polarizer.


  • If used in dusty environments, dust may cause an electrical short inside the product resulting in malfunction.
  • If contaminated by a liquid substance, the polarizer may be discolored. In a worst-case scenario, the liquid could cause electrical failure or corrosion.

Screen Sensitivity and Cleaning Instructions:

  • Screen Cleaning KitThe LCD panel surface is made of a soft film that is vulnerable to scratch. Just to be safe, it is best not to make contact with the screen even with your finger.
  • Since the LCD panel is made of glass, if it happens to fall from a high place or receives a strong shock, the glass could be broken.
  • It is recommended that the product surface be cleaned if it is dirty by using isopropyl alcohol or hexane. Do not use keytone-type acetone liquids such as ethyl or methyl chloride as they can cause damage to the polarizer.
  • Use a proper cleaning cloth (i.e., lint-free cheese cloth) on the surface of the LCD screen.


  • Never disassemble a LCD monitor under any circumstance the device is composed of sensitive electronic parts and components, which can be easily damaged. Leave this up to experienced service professionals.

Power Consumption and Environmental Consideration:

  • Eco AwarenessWhen it is not in use, ensure that the screen is turned off or that the pattern is frequently in change (i.e., a screen saver). With cheaper branded LCD monitors, if the same pattern is displayed for a long period of time, image burn may develop.
  • At the end of its life, it is important to dispose of the monitor in an environmentally sound way as a small quantity of mercury is contained within the backlight’s lamps.
