\section{\label{ref:Displayoptions}Display}
\begin{description}
\item[LCD Settings:]
This sub menu contains settings that relate to the display of the \dap.
\begin{description}
\opt{HAVE_BACKLIGHT}{
\item[Backlight:]
The amount of time the backlight shines after a key press. If set to
\setting{Off}, the backlight will not light when a button is pressed. If
set to \setting{On}, the backlight will never shut off. If set to a time
(1 to 90 seconds), the backlight will stay lit for that amount of time
after a button press.
\item[Backlight (While Plugged In):]
This setting is equivalent to the \setting{Backlight} setting except it
applies when the \dap{} is plugged into the charger.
\item[Backlight on Hold:]
This setting controls the behavior of the backlight when the Hold switch
is toggled. If set to \setting{Normal} the backlight will behave as usual.
If set to \setting{Off} the backlight will be turned off immediately when
the Hold switch is engaged and if set to \setting{On} the backlight will
be turned on and stay on while the Hold switch is engaged.
\item[Caption Backlight:]
This option turns on the backlight a number of seconds before the start
of a new track, and keeps it on for the same number of seconds after the
beginning so that the display can be read to see song information. The
amount of time is determined by the value of the backlight timeout
setting, but is no less than 5 seconds.
\opt{HAVE_BACKLIGHT_PWM_FADING}{
\item[Backlight fade in:]
The amount of time that the backlight will take to fade from off to on
after a button is pressed. If set to \setting{Off} the backlight will
turn on immediately, with no fade in. Can also be set to \setting{500ms},
\setting{1s} or \setting{2s}.
\item[Backlight fade out:]
Like Backlight fade in, this controls the amount of time that the
backlight will take to fade from on to off after a button is pressed. If
set to \setting{Off} the backlight will turn off immediately, with no
fade out. Other valid values: \setting{500ms}, \setting{1s},
\setting{2s}, \setting{3s}, \setting{4s}, \setting{5s} or \setting{10s}.
}
\item[First Keypress Enables Backlight Only:]
With this option enabled the first keypress while the backlight is turned
off will only turn the backlight on without having any other effect. When
disabled the first keypress will \emph{also} perform its appropriate action.
\opt{HAVE_LCD_SLEEP}{
\item[Sleep (After Backlight Off):]
This setting controls how long rockbox will wait before turning off the
display after the backlight is turned off. Turning off the display
saves a little bit of battery power but turning on the display takes
noticeably longer than just turning on the backlight.
}
\opt{HAVE_BACKLIGHT_BRIGHTNESS}{
\item[Brightness:]
Changes the brightness of your LCD display.
}
} % \opt{HAVE_BACKLIGHT}
\opt{archos,h1xx,ipodmini,ipod3g,ipod4g,x5}{
\item[Contrast:]
Changes the contrast of your LCD display.
\warn{Setting the contrast too dark or too light can make it hard to
find this menu option again!}
} % \opt{archos,h1xx,ipodmini,ipod4g,x5}
\opt{HAVE_LCD_INVERT}{
\item[LCD Mode:]
This setting lets you invert the colours of the display.
}
\opt{HAVE_LCD_FLIP}{
\item[Upside Down:]
Displays the screen so that the top of the display is nearest the buttons.
This is sometimes useful when carrying the \dap{} in a pocket for easy
access to the headphone socket.
}
\end{description}
%
\opt{HAVE_REMOTE_LCD}{
\item[Remote-LCD Settings:]
This sub menu contains settings that relate to the display of the remote.
\begin{description}
\item[Backlight:]
Similar to the main unit backlight this option controls the backlight
timeout for the remote control. The remote backlight is independent
from the main unit backlight.
\item[Backlight on When Plugged:]
This controls the backlight when the \dap\ is plugged into the charger.
\item[Caption Backlight:]
This option turns on the backlight a number of seconds before the start
of a new track, and keeps it on for the same number of seconds after the
beginning so that the display can be read to see song information. The
amount of time is determined by the value of the backlight timeout
setting, but is no less than 5 seconds.
\item[First Keypress Enables Backlight Only:]
This controls what happens when you press a button on your remote
while the backlight is turned off. Like for the main unit, if this
setting is set to \setting{Yes}, the first keypress will light up the
remote backlight, but have no other effect. If set to \setting{No},
the first keypress will light up the remote backlight
\emph{and} engage the function of the key that is pressed.
\item[Contrast:]
Changes the contrast of your remote's LCD display.
\warn{Setting the contrast too dark or too light can make it hard to
find this menu option again!}
\item[LCD Mode:]
This setting lets you invert the whole screen, so now you get a
black background and light text and graphics.
\item[Upside Down:]
Displays the screen so that the top of the display is nearest
the buttons. This is sometimes useful when carrying the \dap\ in a
pocket for easy access to the headphone socket.
\opt{h1xx,h300}{
\item[Reduce Ticking:]
Enable this option if you can hear a ticking sound in your headphones
when using your remote.
}
\end{description}
}
%
\item[Scrolling]
This feature controls how text will scroll in Rockbox. You can configure
the following parameters:
\begin{description}
\item[Scroll Speed:]
Controls how many times per second the scrolling text moves a step.
\item[Scroll Start Delay:]
Controls how many milliseconds Rockbox should wait before a new
text begins scrolling.
\opt{HAVE_LCD_BITMAP}{
\item[Scroll Step Size:]
Controls how many pixels the text scroll should move for each step.
}
\opt{HAVE_REMOTE_LCD}{
\item[Remote Scrolling Options:]
The options here have the same effect on the remote LCD as the options
mentioned above have on the main LCD.
}
\item[Bidirectional Scroll Limit:]
Rockbox has two different scroll methods: always scrolling the text
to the left and when the line has ended beginning again at the start,
or moving to the left until you can read the end of the line and scroll
right until you see the beginning again. Rockbox chooses which method
it should use depending of how much it has to scroll left. This setting
lets you tell Rockbox where that limit is, expressed in percentage of
line length.
\opt{HAVE_LCD_BITMAP}{
\item[Screen Scrolls Out of View:]
On lists with long entries that do not fit on the screen using
\opt{recorder,recorderv2fm,h1xx,h300}{\ButtonOn+\ButtonRight/
\ButtonLeft}\opt{ondio}{\ButtonMenu+\ButtonRight/\ButtonLeft}
the complete content will be scrolled right/left. With this option set to
\setting{Yes} the lines can scroll out of view. Otherwise the entries
will only scroll as far as they align to the margins.
\item[Screen Scroll Step Size:]
Determines how many pixels the text should advance in every click when
scrolling the screen.
}
\opt{player}{
\item[Jump Scroll:]
This setting makes text scroll a page at a time instead of a character
at a time. If set to \setting{One time}, \setting{2}, \setting{3} or
\setting{4} it will scroll a line in paged mode that many times and
then scroll it a character at a time. If set to \setting{Always} lines
will always scroll in paged mode.
\item[Jump Scroll Delay:]
Controls how long the delay is before a page is scrolled.
}
\item[Paged Scrolling:]
When enabled scrolling will page up/down instead of changing lines. This
can be useful on slow displays.
\end{description}
%
\opt{HAVE_LCD_BITMAP}{
\item[Status/Scrollbar:]
Settings related to on screen status display and the scrollbar.
\begin{description}
\item[Scroll Bar:] Enables or disables the scroll bar at the left.
\item[Status Bar:] Enables or disables the status bar at the upper side.
\opt{RECORDER_PAD}{
\item[Button Bar:] Enables or disables the button bar prompts for the
``F''-keys at the bottom of the screen.
}
\item[Volume Display:] Controls whether the volume is displayed as a
graphic or a numeric value on the Status Bar. If you select a numeric
display, volume is displayed in decibels.
\fixme{cross-reference to volume setting.}
\item[Battery Display:] Controls whether the battery charge status is
displayed as a graphic or numerical percentage value on the Status Bar.
\end{description}
}
%
\opt{HAVE_LCD_BITMAP}{
\item[Peak Meter:]
The peak meter can be configured with a number of parameters.
\begin{description}
\item[Peak Release:]
This determines how fast the bar shrinks when the music becomes
softer. Lower values make the peak meter look smoother.
Expressed in scale units per 10ms.
\item[Peak Hold Time:]
Specifies the time after which the peak indicator will reset.
For example, if you set this value to 5s, the peak indicator displays
the loudest volume value that occurred within the last 5 seconds.
Larger values are useful if you want to find the peak level of a song,
which might be of interest when copying music from the \dap\ via the
analogue output to some other recording device.
\item[Clip Hold Time:]
The number of seconds that the clipping indicator will be visible
after clipping is detected.
\opt{HAVE_RECORDING}{
\item[Clip Counter:]
Show the number of times the clip indicator went active during
recording in front of the peakmeters.
}
\item[\label{ref:Peakmetersetting}Scale:]
Select whether the peak meter displays linear or logarithmic values.
The human ear perceives loudness on a logarithmic scale. If the Scale
setting is set to \setting{Logarithmic} (dB) scale, the volume values
are scaled logarithmically. The volume meters of digital audio
devices usually are scaled this way. On the other hand, if you
are interested in the power level that is applied to your headphones
you should choose \setting{Linear} display. This setting cannot be
displayed in units like volts or watts because such units depend
on your headphones.
\item[Minimum and maximum range:]
These two options define the full value range that the peak meter
displays. Recommended values for the \setting{Logarithmic} (dB) setting
are {}-40 dB for minimum and 0 dB for maximum. Recommended values
for \setting{Linear} display are 0 and 100\%. Note that {}-40 dB is
approximately 1\% in linear value, but if you change the minimum
setting in linear mode slightly and then change to the dB scale,
there will be a large change. You can use these values for `zooming'
into the peak meter.
\end{description}
}
\item[Default Codepage:]
A codepage describes the way extended characters that are not available
within the ASCII character set are encoded. ID3v1 tags do not have a
codepage encoding contained so Rockbox needs to know what encoding has
been used when generating these tags. This should be ``ISO-8859-1'' but
to support languages outside Western Europe most applications use
the setting of your operating system instead. If your operating system
uses a different codepage and you are getting garbled extended characters
you should adjust this settings. In most cases sticking to
``ISO-8859-1'' would be sufficient.
