Dm642 EVM DIsplay

Hi,
I am new user to DSP board. I connected DM642 board to my system and use
another monitor for display of video and ran the given demos. The demos of
VGA ran and was shown on the monitor whereas NTSC ans PAL didn`t run? Can
anyone tell the reason behing it. Is it possible that the PC monitor
frequency is less than required for the NTSC and PAL application? wHAT CAN
BE THE OTHER ALTERNATIVE TO THIS??

The output from the NTSC and PAL demos doesn't appear on the VGA connector. Those demos generate output as composite video, which VGA monitors don't accept. You'll need a composite monitor, or something that accepts composite inputs like a PC video capture card or a VCR. The signal appears on one of the phono sockets on the edge of the card. Cheers mark-r
