system to dynamically allocate memory resources according to the demands of the system at
any point in time. The key idea in DVMT is to improve the efficiency of the memory allocated
to either system or graphics processor.
When set to Fixed Mode, the graphics driver will reserve a fixed portion of the system
memory as graphics memory. When set to DVMT Mode, the graphics chip will dynamically
allocate system memory as graphics memory, according to system and graphics
requirements. When set to Combo Mode, the graphics driver will allocate a fixed amount of
memory as dedicated graphics memory, as well as allow more system memory to be
dynamically allocated between the graphics processor and the operating system.

Local Flat Panel Scaling
Allows you to determine how various resolutions appear on your LCD display.
Auto: The scaling unit on your graphics card will rescale the image before it reaches your
LCD display. This option results in the best image quality.
Forced Scaling: This option will maintain the original aspect ratio of the chosen resolution
and display it with black bars to the sides/above/below the on-screen image as required.
Disabled: The image isn't scaled at all, but instead your LCD display will run at its maximum
resolution and the image will display in the centre of your LCD display. This may result in a
black border around the sides of the image.
