Output Resolution and refresh rate — Every display device has
an optimal (native) resolution and refresh rate. It is essential
that the output resolution and refresh rate match the display
device's capabilities. The table on the two previous pages
shows the full range of resolutions and refresh rates available
for output signals with these scalers. There are two additional
settings:

User presets — When contrast, brightness, detail, horizontal
and vertical centering, and horizontal and vertical size have
been adjusted, the values can be saved as presets. This allows
the values for the three most commonly used picture control
settings to be instantly recalled, which is useful for handling
inputs with different aspect ratios.
Test pattern — Test patterns help in the configuration of the
output signal. The available patterns include Color Bars,
grayscale, cross-hatch, alternating pixels, crop, 1.33 aspect ratio,
1.78 aspect ratio, 1.85 aspect ratio, 2.35 aspect ratio, and off (no
test pattern).
Freeze — When freeze is enabled, the video output is a still
image of the last active frame. The output will remain frozen
even if the input signal is removed.
Blank — When blank is enabled, no video signal is sent to the
output device, although the on-screen display is still available.
Reset — There are two types of reset. Firmware reset returns all
options, including the firmware to the factory defaults. Factory
reset returns all image options to the factory defaults but keeps
the current version of the firmware. For more information, see
page 3-17.
