TV showing 60hz, not 120hz?

The Direct TV receiver is up converting the 480I signal to 1080I/60. Only when watching true HDTV programming at 720P or 1080I will the picture look much better then standard programming. So unless you have a option in the receiver to set the Direct TV receiver to a native resolution output most likely the satellite receiver will always output 1080I/60.
When your Samsung HLT5089S is receiving a 1080P/24 signal from a BLU-RAY player your display should read 1920 X 1080@24. Also if you were watching a ATSC over the air program your Samsung would display something like 720 X 480 and 1280 X 720 along with 1920 X 1080 depending on the broadcast signal mode. The main thing to remember is that the specs showing up on the screen are what the display is receiving and not what the display is displaying.
I just did a search in the manual for the Samsung HLT5089S and it does not mention 120HZ or 120 frames per second info. http://downloadcenter.samsung.com/content/UM/200703/20070326174110812_BP68-00628B-01L03_0309.pdf
All my research is showing me that the display is a 60HZ display. So yes it will input 1080P/24 but the 1080P/24 signal is being converted to 60fps. Now of course the color wheel spins at 120HZ on most models of DLP’s. For example a 6 segment color wheel will rotate at two revelations per frame on a 4X wheel.
Your Samsung 1080P is still a very good display that refreshes all images at 60 frames per second.

This is were I saw the 120hz display rate: http://www.samsung.com/us/system/con...5089_final.pdf
