Other Parts Discussed in Thread: DM3730, SYSCONFIG

we r able to get the DM3730 display on TV using its TVOUT signals... but TVOUT stops coming if the LCD resolution is greater then 800*600....so what might be the problem???

we r using WINCE6.0 OS... we want to use the TV out @ 1024*768 resolution.....

thnx in advance ......
