sRGB
sRGB is a standard for ensuring correct exchange of colours between different devices
(e.g. digital cameras, monitors, printers, scanners, etc.)
Using a standard unified colour space, sRGB will help represent pictures taken by an sRGB
compatible device correctly on your sRGB enabled Mitsubishi monitors. In that way, the colours
are calibrated and you can rely on the correctness of the colours shown on your screen.
Important with the use of sRGB is that the brightness and contrast of your monitor is fixed to a
predefined setting as well as the colour gamut. Therefore it is important to select the sRGB
setting in the monitor's OSD.
From PC mode, open the OSD by pressing the MENU button of your monitor.

Product Information
Use the down button to select COLOUR SETTINGS and press MENU again.
Then move the down button to select NORMAL COLOUR and press MENU again.
