Poor resolution display...

if the appropriate Display Resolution is properly selected.
Image persistence...
Image persistence happens when a "ghost" of an
image remains on the screen even after the monitor has been
turned off. Unlike the CRT monitors, LCD monitor's image
persistence is not permanent. If an image was on the monitor for
one hour and a "ghost" of that image remains, the
monitor should be turned off for one hour to erase the image.
The supplier recommends that all personal display devices to use
a screen saver at regular intervals whenever the screen is idle.
