Display, Internal Graphics Features | Intel D15343-003 specs

Introduction

Display

•Analog display support

—350-MHz integrated 24-bit RAMDAC that can drive a standard progressive scan analog monitor with pixel resolution up to 1600x1200 at 85 Hz and up to 2048x1536 at 75 Hz

•Dual independent pipe support

—Concurrent: different images and display timings on each display device

—Simultaneous: same images and display timings on each display device

•DVO (DVOB and DVOC) support

—Digital video out ports DVOB and DVOC with 165-MHz dot clock on each 12-bit interface; two 12-bit channels can be combined to form one dual channel 24-bit interface with an effective dot clock of 330 MHz

—The combined DVO B/C ports as well as individual DVO B/C ports can drive a variety of DVO devices (TV-Out Encoders, TMDS and LVDS transmitters, and so on) with pixel resolution up to 1600x1200 at 85 Hz and up to 2048x1536 at 72 Hz.

—Compliant with DVI Specification 1.0

•Tri-view support through DVO B, C port, and CRT

Internal Graphics Features

—Alpha Stretch BLT (via 3D pipeline)

—Anti-aliased lines

—Hardware-based BLT Clipping and Scissoring

—32-bit Alpha Blended cursor

—Programmable 64 x 64 3-color Transparent cursor

—Color Space Conversion

—Three Operand Raster BLTs

—8-bit, 16-bit, and 32-bit color

—ROP support

—DIB translation and Linear/Tile addressing

—Multiple hardware color cursor support (32-bit with alpha and legacy 2-bpp mode)
