11.4 Graphics Interface
You cannot use the U-Boot Setup settings to configure the DVI ® or the LCD panel output. Only some entries
in ' platform.reg ' define for example the boot display or the resolution.
11.4.1 DVI ® Monitor
The best way to apply the DVI ® monitor consists in the usage of EDID data. Example:
IF BSP_NV_DISPLAY
... some settings ...
"MainPanelBpp"=dword:20
"DviHotplugBehavior"=dword:1
"DesktopWidth"=dword:0
"DesktopHeight"=dword:0
"EnableEdidMode"=dword:1
"DesktopScaleMode"=dword:2
"DefaultDdrawCloneMode"=dword:0
"AlwaysVSyncExternal"=dword:1
"FilterScaledDesktops"=dword:1
"EnableDestAlpha"=dword:1
"UseStaticResolutionList"=dword:0
ENDIF
11.4.2 LCD Panel
For a LCD panel you have to define the entries DesktopWidth and DesktopHeight. Only some fixed resoluti-
ons (single channel) are supported. Example:
VGA, WVGA, SVGA and XGA
IF BSP_NV_DISPLAY
... some settings ...
"MainPanelBpp"=dword:20
"DviHotplugBehavior"=dword:1
; This registry will decide the desktop resolution
; * 800x600 (0x320 x 0x258)
"DesktopWidth"=dword:320
"DesktopHeight"=dword:258
"EnableEdidMode"=dword:0
"DesktopScaleMode"=dword:2
"DefaultDdrawCloneMode"=dword:0
"AlwaysVSyncExternal"=dword:1
"FilterScaledDesktops"=dword:1
