I am not an HW expert, but I recall i had spend considerable amount of time with TV out quality issues, even in case of OMAP3EVM. I am not sure whether you have referred to the application note - http://processors.wiki.ti.com/images/4/40/TV_out_application_note.pdf

Thanks,

thanks to your reply

i review the PDF of TV_out_application, i am sure i use the Normal operation, and the Peripheral Components is the same of this document and OMAP3EVM, I guess, is the Phenomena relate of IPU 's Resolution? in fact we test this function by use the DSS Resolution 800X600, and 800X480. is this a SW issue? we must use the TV out PAL/NTSL 720x576 720x480?
