Subject: Problems on LCD display function

Hello,
  I have one problem about LCD display.
I was using the beagle board with Dell S2009W LCD monitor.
The HDMI in beagle board is connected to DVI in Dell monitor.
I use the following parameters to control the display functions.
1. In beagle board BSP, the file
\src\hardware\devg\omap35xx\omap35xx.conf has the setting in the below:
"hsw=20,hfp=128,hbp=64,vsw=4,vfp=24,vbp=24,ivs=1,ihs=1,ipc=1,ieo=0x4,acb
=0,acbi=0,pcd=0x4,ppl=800,lpp=480,irq=25,
disptype=0,lcdfmt=0x1,verbose=1,hcursor=0,cached_mem=1,cache_flush=0"
2. In beagle board BSP, the file
\src\hardware\startup\boards\omap3530\beagle.build has the display
setting in the
following:
/etc/system/config/omap35xx.conf=omap35xx.conf
/etc/system/config/display.conf={
device \{
       drivername=omap35xx
        vid=0
        did=0
       modeopts=/etc/system/config/omap35xx.conf
        display \{
              xres=800
              yres=480
              refresh=60
              pixel_format=rgb565
              
              photon \{
                  enabled=1
                  xoffset=0
                  yoffset=0
                  cursor=software
                  input_group=1
             \}
        \}
    \}
}
  Now the above settings can display the UI(User Interface) picture
generated by our software in Dell S2009W with the resolution 800 * 480.
But I can not change the resolution (800 * 480 is used now) anymore even
if I change the parameters in omap35xx.conf.
  I am confused now that the files omap35xx.conf and beagle.build seem
to be unable to control the LCD display.
  Is there any files need to be modified in the BSP source codes for LCD
display? Or how to modify the parameters in both files correctly?
  If the display control is not a problem, other LCD monitors can be
used to connect with the beagle board. Is it right ?
  Now the BSP source code is from the file
"bsp-nto641-ti-omap3530-beagle-trunk.zip".
  Please give me any clues that can solve this problem. Thanks!
