摘要: A system selects either a first scaler in a host computer or a second scaler in a display device, the first scaler having a predetermined output quality. The system instructs the display device to render a pattern; determines the output quality of the second scaler; and compares the quality of the second scaler with the predetermined output quality and selects the scaler with higher quality.

摘要: A system provides automatic mode detection and scaler control in a display device which is digitally coupled to a display controller. The display controller has a variable active horizontal resolution and a variable active vertical resolution, while the display device has a fixed display device horizonal resolution and a fixed display device vertical resolution. The system determines the variable active horizontal and the vertical resolutions of the display controller; and scales the output of the display controller to the fixed horizontal resolution and vertical resolution of the display device.

摘要: A system positions an image with a plurality of lines on a display device. The system determines the number of black lines required to vertically center the image in a frame of the display device as m+n; displays m black lines using a first horizontal sync period at the start of each frame, the first horizontal sync period being less than the horizontal sync period of the display device; displays each line of the image; and displays n black lines using the second horizontal sync period until the end of the frame.
