Notes on the LCD Panel of the Machine
• The Liquid Crystal Display (LCD) panel of this display has a very thin protective layer of glass which
is liable to marking or scratching, and cracking if struck or pressured. The liquid crystal substrate is
also liable to damage under excessive force or extreme temperatures. Please handle with care.
• The response time and brightness of the LCD panel may vary with the ambient temperature.
• The LCD panel consists of individual pixels to display images and is manufactured according to the
design specifications. While 99.99% of these pixels work normally, 0.01% of the pixels may
remain constantly lit (in red, blue or green) or unlit. This is a technical limitation of the LCD
technology and is not a defect.
• LCD screens, like plasma (PDP) and conventional CRT (Cathode Ray Tube) screens, are also
susceptible to 'screen burn-in' or 'image retention' which can be found on the screen as visible fixed
lines and shades. To avoid such damage to the screen, avoid displaying still images (like On-
Screen Display menus, TV station logos, fixed/inactive text or icons) for more than two hours.
Change the aspect ratio from time to time. Fill the entire screen with the image and eliminate the
black bars whenever possible. Avoid displaying images in 4:3 aspect ratio over a long period of
time, otherwise there may be visible burn marks on the screen as two vertical lines.
