2.3. User Controls.
2.3.1. Direct Brightness Adjustment
Pressing the Br+ or BR- button controls the intensity of the backlight. After adjustment,
the new Brightness value is displayed on the screen until the OSD timeout period expires
(see para. 2.4.5). The new setting is then stored and the display returns to normal.
2.3.2. Direct Contrast Adjustment
Pressing the Con+ or Con- button controls the contrast (video gain) of the picture. After
adjustment, the new contrast value is displayed on the screen until the OSD timeout
period expires. The new setting is then stored and the display returns to normal.
2.3.3. Menu Select
Pressing this button displays picture identification information together with a menu of
icons. To access lower-level functions, press Con+, Con-, Br+ or Br- to toggle through the
menus available for the currently displayed signal type, then press MENU again to select
that function. The MENU button has a similar function to the ENTER key on a computer
keyboard. Exit from a menu is by selecting BACK which returns to the previous level.
When leaving the main menu you will be prompted to save any changes, if you do not
wish to save any changes select NO. Note that Con+ and Br+ have identical functions in
this mode, as have Con- and Br-.
2.4. OSD Menu
At the top of the menu is a line which identifies the type of signal currently displayed. For
computer signals the same section displays the signal resolution, together with horizontal
and vertical frequencies. If its setup has been saved, the user number of that signal is
also displayed. These figures are for guidance only.
2.4.1. Brightness and Contrast
These perform the same functions as the direct button operations in para. 2.3.1 and 2.3.2
above.
2.4.2. The Geometry Menu
Geometry adjustments can be made for all types of input individually, so that if the input
type changes, the geometry adjustment will change with it. Saved settings include one
each for PAL, NTSC, SECAM, SDI and component video.
Additionally, a total of 25 settings may be stored for analogue graphics (RGB and DVI). If
this graphics table is full, further stored settings will over-write the earliest so that the
settings complement contains the latest 25.
1) Edge Adjustment – Picture Size and Position Controls. The four “Edge” controls
shift each edge within available limits. Note that the maximum available shift
depends on the incoming video standard and the display panel type, and may be
restricted vertically. This provides very flexible and easy to use image size and
position control.
2) Moire correction The user can choose from one of four correction tables.
3) Clock (Analogue Graphics only). This sets the total number of input pixels per line
to correspond with the input source, and will normally require adjustment only for
unusual signals.
4) Phase (Analogue Graphics only) This adjusts the internal clock to sample each
pixel as near as possible to the centre. Phase will normally require adjustment for
unusual types of signal.
