<div class="symptoms_section">

SYMPTOMS
When the driver rotates a 800 × 600 or a 640 × 480 screen resolution by 90 degrees, the resolution is not available in the resolution slider of the Control Panel program.

<div class="cause_section">

CAUSE
The Control Panel program filters out any resolution that has a width less than 640 pixels or a height less than 480 pixels. When either of these resolutions is rotated, they fail this test and are filtered out.

<div class="status_section">

STATUS
This behavior is by design.
