GDR 15L Series

CyberResearch® Displays

4.Image Control and Adjustment

There are two important steps in order to ensure that the best possible image quality is now obtained:

4.1Select the correct resolution and refresh rate.

The GDR 15L is intended to run at a resolution of 1024x768 pixels. Although the unit can display in full screen mode at both 800x600 and 640x480, we strongly recommend you now set the resolution to 1024x768.

•Move the slider bar until the screen resolution is 1024x768.

•Change the refresh rate to 60 Hz

•Set the number of colors to 16 million

•Save settings before exiting.

4.2Run the On-Screen Auto Adjust Utility using the buttons on the front of the monitor:

•Click the “Menu” Button once. The On-Screen Menu will now pop up and will already be highlighting the “Auto Adjust” option.

•Click “Select.”

•The display will now resize and reposition until an optimal image is achieved.

•Wait five seconds and the On-Screen Controls will disappear.

Important Note: The panel used in the GDR 15L can operate between

a range of 60 and 75 Hz. The best frequency will depend on the driver card in the PC. If at this stage there is any “noise” on the screen, we recommend the following:

•Try increasing the refresh rate above 60 Hz. Do not exceed 75 Hz.

•Fine-tune the Brightness, Contrast and Sharpness functions using the On-Screen Control.

4.3The GDR 15L is an extremely bright display, operating at 400 nits (400 cd/m2). We strongly recommend that, unless the unit is used in very bright lighting conditions, the brightness be reduced to around 60 to 70% using the On-Screen Control. This helps to eliminate any residual screen noise, and also will greatly prolong the backlight life of the panel.
