hi Badri ,thanks for your help,that above problem has fix .but now i found that use the DEI_LINK_OUT_QUE_VIP_SC
when i use following code to change the resolution,that can not change the resoution,so why?
System_linkControl(SYSTEM_LINK_ID_DEI_HQ_0, DEI_LINK_CMD_SET_OUTPUTRESOLUTION,
¶ms, sizeof(params), TRUE);
