Hi!

I have a custom board having ADV7171 ,ADV7183 and BF532 Processor.By using it i want to display a Frame on the monitor.

ADV7171 is in NTSC mode at the reset.so, i have easily displayed the NTSC Frame on PC monitor(i have a TV tuner which has s-video input and VGA output. By using it i have displayed the frame on PC monitor).

But, when iam displaying the PAL frame , i can't able to get the frame constanly and clearly on the monitor.

I have changed the settings for PAL in ADV7171 then iam trying to display it.......when iam displayng some form of Blurring is coming,but i can see the frame for some time after that it is disappearing.....i don't know what's the problem.....
My display refresh rate 60Hz and Resolutions 1024*768

For NTSC the refresh rate(60Hz) is OK..But for PAL is there any need to change the refresh rate of my PC monitor(My system has only one rate 60Hz.so, i can't able to change the refresh rate).....

or is there any thing i need to take care when iam displaying A PAL frame in the PC monitor.......
