Output Signal - Extron electronics RGB-DVI 300 User Manual

Audio settings (RGB-HDMI 300 A model only)
Gain and attenuation — Gain increases audio levels (0 to +10 dB). Attenuation reduces audio
levels (0 to -18 dB).
Audio delay — When video signals are processed, they can be delayed relative to the
audio signal. The RGB-HDMI 300 A automatically delays audio by approximately 15 ms to
compensate for internal video processing. It also allows the user to set an additional audio delay
to compensate for delays to the video signal introduced by other signal processors and display
devices in the system.

Output Signal

Video signal
Auto-Image — Automatically sizes and centers the input signal to fill the screen of the output
device. Auto-Image can be used to configure each input rate separately, or it can be enabled, in
the Advanced Configuration menu, to automatically size and center each new input rate.
Picture position — Sets the horizontal and vertical centers for the output image and is used
primarily to adjust for aspect ratio.
Picture size — Sets the size of the output image so that it can fill the entire display device and is
used primarily to adjust for aspect ratio.
Detail filter — Uses variable filters to increase or decrease the detail and definition of the
displayed image. The value can be adjusted on a scale from 0 to 127. The default setting is 64.
Brightness — Adjusts the black level of the image on the screen, on a scale from 0 to 127. The
default setting is 64.
Contrast — Adjusts the difference between the input's darkest and brightest levels, on a scale
from 0 to 127. The default setting is 64.
Zoom — Enlarges a portion of the scaled image.
NOTE: Zoom values match picture size values. A "zoomed" image can have a panning effect
applied by using the picture position control.
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 capabilities
of the display device. The Output Resolutions and Refresh Rates table on page 9 shows the full
range of resolutions and refresh rates available for output signals with these scalers. There are
two additional settings:
When Auto is selected, the video converter obtains EDID from the display device. This allows
•
the output signal to be adjusted to match precisely the resolution and refresh rate of the
display.
When Lock is selected, the video converter matches the resolution and refresh rate of the
•
output signal with those of the input signal. This produces a 1:1 non-scaled analog to digital
conversion.
Lock output rate — Allows automatic analog to digital signal conversion without scaling. When
a new input resolution is detected by the scaler, the output rate is adjusted to match. The lock
mode uses the current input configuration settings to create a custom output resolution. If auto
memory is enabled, changes to H/V Start, H/V Active, and Total Pixels are stored and recalled
the next time the input rate is applied. For example, when a 1400x1050 input is applied while
the scaler is in lock mode and Active Pixels are changed to 1410 and Active Lines are changed
to 1055, the next time the scaler detects a 1400x1050 input, the output resolution will be
1410x1055.
This allows the user to exactly dial in each video signal when multiple or non-standard sources
are used.
NOTE: Some display devices do not accept unusual input resolutions. Extron recommends
that, for most applications, only Total Pixels, H/V Start, and Phase are adjusted in Lock
mode. Leave the Size and Postion picture controls at their default values, since adjusting
them disables the direct analog to digital conversion and may introduce scaling artifacts.
