PICTURE

Use these commands to fine tune the image

Tint

Detail

Noise Reduction

NOTE: Adjusting Detail – The Detail and Noise Reduction settings have been optimized for the scan rate and resolution of the NR Series for most sources. However, the viewers tastes and the types of software used may require making –adjustments of these settings to fine tune the image. These controls are very effective to either increase detail or to help clean up poor quality video material. It is recommended that adjust- ments be made in small increments until the desired results are achieved. It is important to not use too much Detail as the image will start to look artificial.

DISPLAY

Use these commands to adjust the image position and edge blanking. It is recommended to adjust sizing and blanking in the display device first. This should be done by a qualified technician.
