Optimizing the Video
The TPR150 receiver features cable equalization controls for high and low
frequency adjustments and RGB skew control to compensate for misconvergence of
colors that can result from long CAT 5 cable runs. The following steps detail how
to use these features to optimize the output image.
These adjustments should be made with the highest resolution input selected
on the TPT150 transmitter.
1 . Carefully set the rear panel RGB skew controls to minimum
(fully counterclockwise).
2 . Power up the transmitter, receiver, and display.
3 . Select the highest resolution.
4 . As needed, use the front panel low
frequency control to eliminate any
visible image smear.
a . If necessary, press and release
the Cable Equalization Select
button to light the Low Frequency LED.
b . Press the + side of the button to increase the amount of equalization
applied to the output signal’s low frequency range. Press the – side of
the button to decrease the amount of equalization.
5 . As needed, use the front panel high frequency control to maximize the detail
and sharpness.
a . If necessary, press and release the Cable Equalization Select button to
light the High Frequency LED.
b . Press the + side of the button to increase the amount of equalization
applied to the output signal’s high frequency range. Press the – side of
the button to decrease the amount of equalization.
6 . If the red, green, and blue video are not properly aligned, use a Tweeker or
small screwdriver to gently adjust the red, green, and/or blue Skew
Adjustment controls to correct for the delay inherent in network (CAT 5)
cable.
The Skew Adjustment controls are sensitive. Make each adjustment carefully.
7 . Repeat steps 4 through 6 to fine tune the adjustments.
