26 MLC-810 TUFF VIEW LCD Monitor
Note
A PC’s BIOS does not support touch screen operation. The touch screen can
only be used once the operating system has started and only after the touch
screen drivers have been installed (described in Chapter 8, Touch screen
operation).
7.2. Optimizing sunlight readability
To optimise reading the screen in direct sunlight, we recommend:
 Setting the Contrast Ratio in the OSD to 75%. This is the default.
 Setting the Brightness in the OSD to 60% (the default is 50%). This level (60%)
does impact the normal light-level viewing – it washes out some of the colours.
 Use a high-contrast colour scheme on the PC.
7.3. Brightness control
The front panel keypad contains brightness Up and Down buttons. Pressing these
buttons increases and decreases the backlight brightness – there are 64 levels. When
one of the buttons is pressed, the backlight brightness setting is displayed on the LCD.
Figure 7. Backlight brightness level on-screen display
These buttons control the actual brightness of the backlight (it does not do a colour shift –
which is how most LCD monitors work). The brightness setting has a direct impact on
power consumption. The lower the backlight brightness, the lower the power
consumption. Refer to section 5.5, Power consumption, for power consumption figures.
7.4. On Screen Display (OSD)
The On Screen Display (OSD) allows you to tune the image displayed on the monitor to
the PC it is connected to.
7.4.1. Navigating through the OSD menus
To use the OSD:
 Press the Menu button on the front panel keypad to bring up the OSD menu. A
valid video input signal must be present for the OSD menu to be displayed.
 The OSD menu is divided into two sections: the main menu tabs (shown in the top
half of the OSD window), and the menu options (shown in the bottom half of the
OSD window).
