Introduction
The graphics features on the GMCH include:
1.4.6
Display Interfaces
The GMCH provides interfaces to a progressive scan analog monitor and two DVOs (multiplexed
with AGP) that can drive an ADD card. The digital display channels can drive a variety of DVO
devices (e.g., TMDS, LVDS, and TV-Out).
The GMCH has an integrated 350 MHz RAMDAC that can directly drive a progressive scan
analog monitor up to a resolution of 2048x1536 at 60 Hz.
The GMCH provides two multiplexed DVOs that are can drive a 165 MHz pixel clock. The
two DVO ports can be combined to drive larger digital displays.
The GMCH is compliant with the
Digital Visual Interface (DVI) Specification, Revision 1.0
(www.ddwg.org/register/download.htm). When combined with a DVI-compliant external device
and connector, the GMCH has a high-speed interface to a digital display (e.g., flat panel or digital
CRT).
