hello.
you must read the manual.

a six word response to a six word post. if you want better... post details.

some higher end receivers which have an OSD will have a section labeled setup and will automatically calculate delay. they often provide a speaker which connects up to the receiver for this purpose.

if you have a HTIB or lower end unit you may only have the receiver faceplate display but still may have a provided microphone and automatic delay calculator.

you need to read the manual regarding this.
