CRT Power Management (VESA DPMS)

The Apollo MVP4 Graphics Controller conforms to the standard power management schemes defined by VESA™ for CRTs. The

Apollo MVP4 Graphics Controller supports four states of VESA™ Display Power Management Signaling (DPMS), which

decrease 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.

Digital Flat Panel (DFP) Interface

The Apollo MVP4 DFP interface is designed to support industry standard TFT and DSTN panels through an external TMDS

transmitter. A Silicon Image SIL140 TMDS transmitter can be used to complete this interface.

Video Capture Interface / ZV Port

A video capture / ZV port is supported for video devices such as MPEG1 and MPEG2. Additionally, a zero-wait state host write

buffer, read cache, and memory mapped I/O increase operating speeds and contribute to peak performance levels.

All I/O

interfaces are 5V tolerant, capable of interfacing with external devices operating at 5V, even though the Apollo MVP4 Graphics

Controller runs at 2.5V internally. Graphics system throughput is further enhanced by a command FIFO, allowing maximum bus

transfer speed for applications such as Windows™ or AutoCAD™ that directly access video memory.

Complete Hardware Compatibility

The Apollo MVP4 Graphics Controller is fully compliant with the VESA™ DDC and VAFC standards. The Apollo MVP4

Graphics Controller is 100% VGA compatible at both the BIOS and Driver level, allowing full compatibility with virtually any

VGA application software. The Apollo MVP4 Graphics Controller provides hardware support to DirectDraw™, offering high-

speed game graphics on Windows 95

supporting a unique ID for each customer and a unique ID for each model.
