How do I change the refresh rate of my samsung hl61a650 dlp tv from 60mh to 120mh?

That's ';Hz';, not ';mh';, but anyway - it's already a 120Hz set. It is upsampling non-120Hz sources. According to the specs it only supports up to 60 Hz sources. When it says it's running at 60 Hz, that's the frame rate of the source, not the display.



There are no 120Hz sources in consumer video.
