Multi-monitor is supported on Intel® 815EM chipset-based laptops only if a separate PCI graphics controller is used to support additional monitors. In this configuration, the Intel 815EM chipset graphics controller can be either the primary or the secondary display adapter.
If only the Intel 815EM chipset integrated graphics controller is used in the laptop, then only simultaneous display to the internal LCD and a VGA monitor is supported. You cannot have separate desktop (multi-monitor) between the two displays, only a mirrored image between the two displays because only one display pipe is supported in this configuration.
System requirements for multi-monitor on an Intel 815EM chipset-based laptop:
- Integrated Intel® 815EM chipset or integrated AGP graphics adapter
- Integrated PCI graphics adapter that supports multi-monitor
- Two or more display devices, including possibly a VGA monitor, the Internal LCD display or a TV (if TV-out is supported by the laptop).
- Windows* 98, Me, 2000, or later
- The latest graphics drivers for the Intel® 815EM chipset
To use multi-monitor with the Intel® 815EM chipset:
1) Install the latest graphics drivers for the Intel® 815EM chipset, or if an integrated AGP graphics adapter is present, make sure the latest drivers for it are installed.
2) Install the latest graphics drivers for the Integrated PCI graphics chip.
3) Restart the computer.
4) Go into Start > Settings > Control Panel > Display > Settings and click on the picture of monitor 2. Click on the Yes button to enable the second monitor.
5) Click the Apply button. The secondary monitor should now be enabled.
Note: To reverse the primary and secondary display adapters, enter the BIOS setup and look for a setting called "Init display first", or something similar. Set this to "PCI" if the PCI video should be the primary display adapter. Set it to "AGP" or "Onboard" if the integrated video should be the primary display.
