efficiency for the graphic controller. The employment of
SGRAM provides an abundant memory bandwidth for both
high resolution display and playback. A minimal SGRAM
interface requirement of four SGRAMs for a 1280x1024-64k
color SXGA minimizes chip count, system cost, and board
space for a cost-effective design solution.
With the support of AGP, the Video 107AGP 3D & TV has
access to system memory with sideband addressing. In the
execute mode, the Video 107AGP 3D & TV is able to use both
the graphics memory and the system memory as the primary
graphics memory. As a result, 3D rendering performance and
quality are greatly enhanced.
2.16 Hi-Res and Hi-Ref Display Support
The Video 107AGP 3D & TV display enhancements
dramatically improve CRT resolution. These enhancements
include support of non-interlaced 1280x1024x64K,
1024x768x16M, 800x600x16M, and 640x480x16M colors for
"full spectrum" color. Extended text modes of 80 or 132
columns by 25, 30, 43, or 60 rows provide an extended
graphics area frequently used in many spreadsheet and
database applications. Extended graphics and text modes are
supported by software drivers that provide a "ready-to-go"
solution, minimizing the need for additional driver
development.
A virtual screen can be created with the Video 107AGP 3D &
TV.
When this function is enabled, a selected portion of a large
image can be shown on a smaller display. The image can
also be moved across the whole screen, either up or down.
The Video 107AGP 3D & TV is able to automatically detect
DDC monitors with I²C signaling.
2.17 CRT Power Management (VESA DPMS)
The Video 107AGP 3D & TV conforms to standard power
management schemes, as defined by VESA™ for CRT.
The Video 107AGP 3D & TV supports four states of VESA™
Display Power Management Signaling (DPMS), which
decreases monitor power consumption after timeout periods.
VESA™ DPMS power down states (ready, standby, suspend,
and off) specify HSYNC and VSYNC signals to control the
monitor power down state.
