Picture Mode
Press the PICTURE button to display a full screen representation of the video
signal present at the selected input.
NOTE. Due to the number of pixels in the LCD display of the waveform monitor,
not all of the video content (particularly in HD formats) can be reproduced with
100% accuracy by this display module. The picture display offers a means of
visually identifying the content present at the active input and is not designed to
replace the rear-panel PIX MON outputs, which contain all of the video content.
Press the PICTURE button again to display the Picture menu. Use the Safe Area
soft key to display the Safe Action and Safe Title graticules, which comply with
SMPTE RP218. The safe area graticules do not appear in the thumbnail picture.
Since the full-size SD picture display is cropped, use the SD Picture Half Size
setting to view the complete picture when you are monitoring SD signals.
Use the Grat/Gamut Default Setup submenu of the Configuration menu to enable
the display of decoded closed captioning text in Picture mode.
Use the Video Inputs/Outputs submenu of the Configure menu to enable or
disable bright-ups, or contrast patterns, to show areas that are out of gamut, or to
show the selected line or sample.
Use the Display menu to enable a thumbnail picture that appears in other display
modes.
