Barco DCS-200 manual Tip

4. Operation

Using the Setup Menu

For information about adjusting these inputs, refer to the “Image Adjust” section on page 60.)

Important

The Timing Adjust Menu does not appear in the menu tree if the analog input is being undersampled for the following resolutions:

•1920x1080p@60 (173.0 MHz)

•1920x1200p@60 (193.25 MHz)

•2048x1080p@60 (183.75 MHz)

The following functions are available:

•Auto Config — This function performs an automatic input configuration on the analog source on Program. When Auto Config is selected, the DCS-200 finds the first and last pixel on each edge of the selected input, and ensures (to the best possible extent) that the entire image is visible. In addition, the system automatically phases the input to determine the correct sampling phase.

Tip

Ensure that there are non-black pixels around the extreme edges of your active video, in order for the image to be properly sized by the Auto Config function. For example, if you use a Windows desktop with a high luminance background, the Auto Config function will be accurate. If, on the other hand, you use a desktop image with a black border, the image will not be properly sized.

Note

Auto Config applies to analog input sources only. This function is identical to the Auto Config function in the Image Adjust Menu.

•Sampling — select this function to change the sampling for the selected input. Available values are: Oversample and 1:1 (default). Please note:

~When 1:1 Sampling is selected, the system provides pixel-for-pixel sampling, and generally better image quality.

~When Oversample is selected, the system performs multiple samples for every pixel, with a resulting “softer” image.

~Oversample is only available for RGB and YPbPr analog inputs.

~All other input types have defined sample clocks that are inherently 1:1. If the input is set to one of the other types, the value is [1:1].

•Phase A, Phase B — These two selections are advanced features which enable you to adjust the sample phase of the system’s two scalers. Typically, they do not need to be adjusted. Refer to the “Adjusting Sample Phase” section on page 59 for instructions.

The six “Active Area” values are initially filled in by the Auto Config command, or set to their default values. You can adjust values for Analog RGB or YPbPr sources only. Digital and decoded sources show values in brackets.

Please note:

•When sampling is set to 1:1, values are the true timing measurements for the analog RGB or YPbPr inputs.
