VG Series Modero Touch Panels
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.
10. Once done making these adjustments, press the Done button to temporarily save these modifications and place the
grey RGB Adjustments bar back onto the bottom of the screen. Pressing the Cancel button returns you to the RGB
Settings page without temporarily saving your changes.
11. Press anywhere on the background image to exit from the Full Screen Edit mode and return to the RGB Settings
page.
12. In the RGB Settings Page, press the Save Settings button to save your changes to the NXA-RGB card. Cycling
power to the panel before saving your settings can cause your pages to shift back to their original locations.
13. Press the Back button to return to the Setup page.
