Advanced Video Controls
This section is about making adjustments for the LCD, and switching display devic-
es.
Video Driver Controls
The video interface lets you change the screen resolution and color output to what-
ever is most comfortable/efficient for you. This is a matter of hardware, video mem-
ory and the driver for your operating system.
Video Memory
The Model A computer system does not feature dedicated video memory, but auto-
matically and dynamically allocates as much (up to 256MB maximum) system mem-
ory (RAM) as needed to the video system. You can define the amount of system
memory to be allocated from the BIOS (see “Frame Buffer Size: (Advanced
Menu)” on page 5 - 8). The system returns whatever memory is no longer needed to
the operating system.
NVIDIA TurboCache
NVIDIA® TurboCache™ technology (Model B & C computers only) allows the
GPU so share the capacity and bandwidth of dedicated video memory and dynami-
cally available system memory. The TurboCache Manager dynamically allocates
memory for maximum system performance.
