Changing the Display Settings for the Projector | Dell PP12S

Considerations for Display Resolution and Aspect Ratio in Clone Mode

If the projector has a lower display resolution and aspect ratio than the Tablet-PC display, then the Tablet-PC graphics subsystem uses the lowest display resolution and aspect ratio. Changing to a lower display resolution and aspect ratio alters the image quality.

For example, if the Tablet-PC has a display resolution of 1280 x 800 pixels with a 16:10 aspect ratio and the projector is using a 1024 x 768 display resolution with a 4:3 aspect ratio, then you may notice that:

•The projected image is not as sharp as it would be with a 1280 x 800 display resolution. The loss of sharpness is particularly noticeable when reading text.

•Round objects appear flattened. This alteration is a result of shifting from the 16:10 to the 4:3 aspect ratio.

Extended Desktop Mode

Extended desktop mode enables you to configure two displays that each have their own attributes. You can use the Tablet-PC display in tablet mode with portrait orientation using a 1280 x 800 resolution, and the projector can use the standard landscape orientation at a lower resolution and aspect ratio.

When using extended desktop mode, you start applications on the Tablet-PC and then "drag" the applications that you want to be viewed from the projector to the extended desktop. Extended desktop mode is useful when you want to maintain user activity on the Tablet-PC without displaying this activity with the projector.

NOTE: When you initially connect the Tablet-PC to a projector, the Windows operating system asks you to specify default display settings. To enable extended desktop mode, select Show different parts of my desktop on each display (extended). To send the Tablet-PC display image to the projector, use the <Fn><F8> key combination. You can then "drag" the applications you want to project from the Tablet-PC to the extended desktop (the projector). You can change the default display settings at a later time.
