Modero VG Series Touch Panels - Instruction Manual
Although these same options are available within the main RGB Settings page, these RGB image controls provide you with
UP/DN arrows for accurate value entry adjustments. These controls allow you to set the RGB properties of the incoming
image/video on the NXA-RGB.
NOTE: One of the first things to look at when trying to adjust your image, is the Phase value. Adjustments to this value can help
troubleshoot most image issues.
3. Use the UP/DN Phase buttons to alter the RGB tracking/signal level of the incoming image/video. These values cycle back thru
0 and on after reaching 31.
4. Use the UP/DN H Position buttons (from the RGB Geometry popup dialog) to adjust the horizontal location and move the
image (left-right) on the screen. These values cycle back thru 0 and on after reaching 255.
5. Use the UP/DN H Size buttons (from the RGB Geometry popup dialog) to adjust the horizontal height and stretch the image on
the screen. These values cycle back thru 0 and on after reaching 255.
6. Use the UP/DN V Position buttons (from the RGB Geometry popup dialog) to adjust the vertical location and move the image
(up-down) on the screen. These values cycle back thru 0 and on after reaching 255.
7. Use the UP/DN Brightness buttons (from the RGB Brightness popup dialog) to adjust either the overall or individual Red,
Green, and Blue brightness of the incoming image/video. The All Brightness bargraph gives a visual representation of the
overall brightness level and cycles through an entire turn.
8. Use the UP/DN Contrast buttons (from the RGB Contrast popup dialog) to adjust the overall or individual Red, Green, and Blue
contrast of the incoming image/video. Increasing the value can increase sharpness. This All Contrast bargraph gives a visual
representation of the overall contrast level and cycles through an entire turn.
9. To correct for a blurry image and adjust the Red, Green, and Blue signal skew it is recommended that:
Skew adjustments should be made at FULL SCREEN mode and use the panel’s native resolution. In the case of a 1500VG
panel (as seen above) that native resolution is 1024 x 768. Set the RGB Input Resolution value accordingly (done via the
RGB Input Resolution slider).
Do your skew adjustment using an image which contains single pixel-wide white vertical lines (such as those seen in
FIG. 111). This allows you to verify that your RGB signals are being received at the same time.
The lines in circle A of FIG. 111, show how all three signals are in sync and overlap to produce the single white line.
The lines is circle B of FIG. 111, show how the Red signal is being delivered with a slight delay and is "throwing off" the
color of the line. Altering the Red Skew value can compensate for this delay and re-align the image.
