7.3Show native resolution

Graphics

Native resolution of the LCD panels = 1024 pixels x 768 pixels (4:3)

Reality(SXGA)

Native resolution of the LCD panels = 1366 pixels x 1024 pixels (4:3)

Reality(SXGA+)

Native resolution of the LCD panels = 1400 x 1050 pixels (4:3)

What can be done ?

The aim here is to always show the resolution of the source independently of the resolution of the LCD panels. This way better image reproduction is obtained since no up or down scaling is done on the source.

Note that native resolution refers here to the source and does thus only have sense when handling data sources (greyed out for video sources).

Depending on the type of projector the “show native resolution” function will handle the sources as follows:

The default mode is used if the show native resolution and thefull screen function are off.

The default mode shows always the native ratio and forces the native resolution of the panels (part of the image blanked where needed)

When show native resolution is ON and the resolution of the source is higher than the panel resolution , use the arrow keys to scroll through the image (pan).
