After installing the Intel® Embedded Media and Graphics Driver, Microsoft Windows selects a default display mode for the initial startup of the system. This is an 800 x 600 resolution in 16-bit or even 32-bit color mode.
In some cases, particularly with EDID-less LVDS displays, the 640 x 480 resolution may not be supported, so the default mode selected by Microsoft Windows must be changed. Otherwise, the display may not work after installation of the Intel® Embedded Media and Graphics Driver.
This default mode can be changed by adding the following registry keys to the [iegd_SoftwareDeviceSettings]section of the iegd.inf file:
HKR,, DefaultSettings.XResolution, %REG_DWORD%, 1024
HKR,, DefaultSettings.YResolution, %REG_DWORD%, 768
HKR,, DefaultSettings.BitsPerPel, %REG_DWORD%, 32
HKR,, DefaultSettings.VRefresh, %REG_DWORD%, 60
The example above makes the default resolution 1024 x 768, with a 32-bit color depth and a refresh rate of 60 MHz.
