Fixed pixel displays — selecting the optimum resolution and refresh rate

Display devices that are based on LCD, DLP, D-ILA, and plasma technology have a specific number of pixels, a native resolution. These displays typically can show higher or lower resolution signals, but can only do so by scaling the image up or down to the native resolution. To avoid additional image scaling by the display (and more processing is inherently bad for image quality), it is important to know your display’s native resolution.

Check the display’s operation manual to determine its native resolution. Set the scaler to match this native resolution. The scaler’s refresh rate should be set to 60 Hz for most LCD, plasma, D-ILA, and DLP projectors.

Higher refresh rates are not recommended for these display technologies. They usually do not improve the image and may cause compatibility problems.
