Acer 521 manual Normal operation

Item (NB Cont.)		Specification
Features	•	Hardware cursor up to 64x64 pixels in 2 bpp, full color AND/XOR mix,
		and full color 8-bit alpha blend.
	• Hardware icon up to 128x128 pixels in 2 bpp, with two colors,
		transparent, and inverse transparent. AND/XOR mixing. Supports 2x2
		icon magnification.
	•	Virtual desktop support.
	• Support for flat panel displays via VGA.
	VGA Output
	• Maximum resolutions supported by the VGA output for different refresh
		rates are:
	• 2048x1536 @85Hz (pixel clock at 388.5MHz) for 4:3 format
	• 2560x1440 @75Hz (pixel clock at 397.25MHz) for 16:9 format
	• 2456x1536 @60Hz (pixel clock at 320MHz) for 16:10 format
	• 1.3.10 Integrated LVDS Interface
	• Integrated dual-link 24-bit LVDS interface.
	• 805 Mbps/channel with 115 MHz pixel clock rate per link (230 MHz
		maximum pixel clock).
	• FPDI-2 compliant; compatible with receivers from National
		Semiconductor, Texas Instruments, and THine.
	• OpenLDI compliant excluding DC balancing.
	• Programmable internal spread spectrum controller for the signals.
	System Clocks
	• Support for an external clock chip to generate side-port memory, PCIe,
		and A-Link Express II clocks. Alternatively, internal generation for these
		clocks, with clock input from an SB800-series Southbridge, can be
		used (subject to characterization with actual RS880M and SB800-
		series devices).
	Power Management Features
	• Single chip solution in 55nm, 1.1V CMOS technology.
	• Supports ACPI 2.0 for S0, S3, S4, and S5 states.
	• Full IAPC (Instantly Available PC) power management support.
	• Static and dynamic power management support (APM as well as ACPI)
		with full VESA DPM and Energy Star compliance.
	• The Chip Power Management Support logic supports four device power
		states defined for the OnNow Architecture - On, Standby, Suspend, and
		Off. Each power state can be achieved by software control bits.
	• Hardware controlled intelligent clock gating enables clocks only to
		active functional blocks, and is completely transparent to software.
	• Support for Cool'n'Quiet. via FID/VID change.
	• Support for AMD PowerNow!..
	• Clocks to every major functional block are controlled by a unique
		dynamic clock switching technique that is completely transparent to the
		software. By turning off the clock to the block that is idle or not used at
		that point, the power consumption can be significantly reduced during
		normal operation.
	• Supports AMD Vari-Bright., ATI PowerXpress., and ATI PowerPlay.
		(enhanced with the ATI PowerShift. feature).
	• Supports dynamic lane reduction for the PCIe graphics interface when
		coupled with an AMD-based graphics device, PC Design Guide
