Optimizing Video — An Overview
After the input and output connections have been completed, both the MLS 608 D and
the MTP/HDMI U R need to be configured to optimize the video.
Setting the Peaking and Level on the MTP/HDMI U R
Image sharpness is adjusted with the Peaking control. This applies only to the analog side
of the device. Increased peaking compensates for mid- and high-frequency detail loss.
Minimum setting (full counterclockwise) is zero peaking.
Image brightness is adjusted using the Level control.
NOTE: To avoid possible video loss due to errors in the video format detection, the
user should always start with minimal level and peaking, then only increase
values as required
.
To adjust level and peaking between the MLS 608 D and the
MTP/HDMI U R receiver:
1. Connect an oscilloscope (preferred) or a monitor (acceptable) to the RGB output of
the MTP/HDMI U R receiver.
2. If using an oscilloscope, apply a white field test pattern to inputs 1, 2, or 3 on the
MLS 608 D. The Extron VTG 300 or VTG 400 is recommended to provide the test
pattern.
3. If using a monitor, apply a grayscale or color bars test pattern to the input.
NOTE: The signal applied should be an RGB signal.
4. Observe the oscilloscope (or monitor) with a critical eye while you adjust the front
panel input level and peaking controls to compensate for signal loss between the
MLS 608 D and the MTP/HDMI U R.
If using Input 4 on the MLS 608 — setting level and peaking via software
Follow the steps 1 to 3 as given in “To adjust level and peaking....” above:
1. Start the DSP Configurator software program and connect to your device. See the
DSP Configurator section for software installation details.
2. Click View>Video I/O (or press <F4>); this changes the
window to the MLS workspace view. Double click on the MTP
on the Input 4 (left) side of the workspace view. The Input MTP
Settings dialog box appears (see image at right).
3. Observe the oscilloscope (or monitor) with a critical eye and
adjust the level using the slider. Adjust the peaking by using
the up and down arrows. Disconnect test equipment when
finished.
