Optimizing Video

Setting the Peaking and Level on the MTP/HDMI U R

Image sharpness is adjusted with the front panel Peaking adjustment knob.

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 adjustment knob.

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 increase values as required.

Setting the Skew on the MLS 608 D

Adjusting output skew between the

MLS 608 D and the receiver:

1. Connect an oscilloscope (preferred) or a monitor

(acceptable) to the RGB output on the MTP/HDMI U R.

2. Apply a crosshatch test pattern to input 1, 2, or 3

on the MLS 608 D.

3. Use the test equipment or examine the video image

with a critical eye to determine which video signal

(red, green, or blue) is most shifted to the left.

4. Within the DSP Conﬁgurator program, click View > Video I/O (or press <F4>) to access the MLS workspace view. Double-click

MTP on the output (right) side of the workspace view. The Output MTP Settings dialog box appears (see image above).

5. Adjust the furthest left video signal by using the up and down arrows for the relevant signal color, and repeat as needed until

all three colors are aligned correctly.

Adjusting input skew if using Input 4

Follow the steps 1 to 3 as given in “Output skew”, above. Then:

1. Within the DSP Conﬁgurator program, click View > Video I/O (or press <F4>) to access the MLS workspace view.

Double-click MTP on the output (right) side of the workspace view. The Output MTP Settings dialog box appears.

2. Adjust the furthest left video signal by using the up and down arrows for the relevant signal color, and repeat as needed until

all three colors are aligned correctly.

Selecting the MLS 608 D Output Prepeaking

1. Click View > Video I/O (or press <F4>); this changes the window to the MLS workspace view. Double-click on the MTP on

the output (right) side of the workspace view. The Output MTP Settings dialog box appears.

2. Toggle the Pre-peak box on or off as desired.

NOTE: For other video conﬁgurations, such as RGB delay or input video format swapping, see the DSP Conﬁgurator Help ﬁle.

Adjusting level and peaking between the MLS 608 D and the 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) 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.

Setting level and peaking via software if using Input 4 on the MLS 608

Follow the steps 1 to 3 as given in “Adjusting level and peaking...” above. Then:

1. Start the DSP Conﬁgurator software program and connect to your device. See page 7 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) and adjust the

level using the slider. Adjust the peaking by using the

up and down arrows. Disconnect test equipment when

ﬁnished.
