How is a 720p picture displayed on a television with a native resolution of 1366 x 768 pixels?
1366 x 768 pixels is a commonly found non-standard display resolution derived from the computing world where XGA resolution is 1024 x 768 pixels. Increasing the width to a widescreen aspect ratio gives a corresponding horizontal resolution of 1366 pixels. Internally most televisions won’t simply display the input data pixel for pixel. In the case of 1366 pixel displays showing a 720p, the signal processor inside the television re-samples (or overscans) the input to a higher internal resolution which is then mapped to the available display pixels. How noticeable the re-sizing will be will depend on the quality of the internal electronics and how critical you are as a viewer. Although you may be tempted to search for a native 720p display, this re-sampling is quite common where non-native resolution signals need to be displayed, for example down-sampling 1080i/p content or up-sampling standard-definition signals.
