BARCO Controller Control Panel Settings • Clone The primary display is cloned to the secondary display. Color Format • 24-Bit TrueColor Mode • 30-Bit TrueColor Mode (HDR) Display Resolution • Sets display resolution for 1 or 2 displays. Note: To switch out of SingleView or Clone mode, the buttons in this Control Panel page must be used. The main Windows Control Panel cannot be used. Depending on your system, certain configurations can be disabled.
BARCO Controller Control Panel Settings OpenGL and Direct3D The OpenGL and Direct3D pages of the Advanced Properties page are divided into two sections: Main Settings and Custom Settings. Main Settings In the Main Settings section there is a slider bar which allows the user to adjust the OpenGL or Direct3D settings for optimum performance, optimum quality or for a point in between. There is also a checkbox provided for enabling Custom Settings.
BARCO Controller Control Panel Settings Please refer to the on-line help (click on the “?” in the control panel’s openGL tab) for more information on using advanced features such as Anisotropic Filtering. SMOOTHVISION The Advanced Settings tab enables you to apply ATI’s SMOOTHVISION technology for full-scene anti-aliasing. SMOOTHVISION improves image quality by removing jagged edges (anti-aliasing) from 3D images, resulting in smoother, more natural looking objects.
BARCO Controller Control Panel Settings OpenGL Profiles The Configuration page enables you to customize display profiles for individual applications. Typically, you would change these settings for one or more of the following reasons: • Diagnostic purposes. • Fine-tuning a specific application/system configuration. • Specific settings recommended by your hardware or software documentation. • Tuning your application/system environment for best performance and memory usage.
BARCO Controller Control Panel Settings configuration controls on this tabbed dialog to obtain the desired display parameters for the selected application. To remove the selected configuration profile completely, select the name of the application from the Configuration Profiles list box and click Delete. Note: You cannot delete the factory-set configuration profiles. Click the Apply or OK button to enable your Configuration settings.

Disable RGB To Static Gray Color Translation Select Disable RGB To Static Gray Color Translation if you wish to have RGB values equally weighted, with 1/3 each. When not selected, then the International Commission on Illumination (CIE – Commission Internationale de I’Eclairage) model will be adapted, which weights the colors as 59% Green, 30% Red, 11% Blue.

Precautions Precautions 1. Optimize the lifetime of your display Enabling the Display Power Management System (DPMS) of your display (in the display’s Settings menu) will optimize its diagnostic lifetime by automatically switching off the backlight when the display is not used for a specified period of time. By default, DPMS is enabled on your display, but it also needs to be activated on your workstation. To do this, go to “Power Options Properties” in the “Control Panel”.
Precautions diagnostic performance of the product. To ensure optimal product quality, Barco applies strict selection criteria for its LCD panels. To learn more about LCD technology and missing pixels, consult the dedicated white paper available at www.barcomedical.com. 4. Enhance user comfort Every Barco multi-head display system is color matched with the highest specification in the market. Barco recommends keeping color-matched displays together.
Display controls Display controls Overview of controls The front controls are soft touch keys. When you touch any of them while no on-screen display (OSD) is on the screen, the front illumination is switched on for a few seconds.
