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. 113). This allows you to verify that your RGB signals are being received at the same time.

-The lines in circle A of FIG. 113, show how all three signals are in sync and overlap to produce the single white line.

-The lines is circle B of FIG. 113, 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.

11.Press anywhere on the background image to exit from the Full Screen Edit mode and return to the RGB Adjustment page.

12.In the RGB Adjustment 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.
