About residual images
-When a still image is being displayed for a long period, image
retention might occur.
retention might occur.
-Image retention can be removed by displaying motion images
or turning off the monitor. However, the longer the still image is
being displayed, the harder to remove the image retention,
therefore, the solutions mentioned above should be taken
periodically.

Precautions for space between displays
（multi-display）
About thermal influence
-In particular, when monitors are installed one above the
other, the temperature raise of topside monitor cause of the
exhaust heat from downside monitor.
Regarding the countermeasure against temperature, Please
keep the clearance in P.3.
In fact, when installing multi-display, it is hard to keep the
clearance in P.3. Therefore, please keep the temperature
requirements to do the countermeasures as below.
