I received a new Samsung B750 TV and proceeded to hook up a number of devices to it to test it out. I have 3 different HDMI cables:
1) Microosft XBOX HDMI cable
2) Monster High Speed HDMI (this is a brand new $80 cable that I ordered with the TV)
3) Sony High speed HDMI (borrowed from a friend)
All 3 cables worked fine with a BlueRay player I borrowed from a friend. On to the XBOX.....
With the XBOX cables 1 and 2 refused to provide any picture at all. The Samsung would get a signal, but would say "mode not supported".
With cable 3 I was able to get a picture but the color was off and there were wierd lines. After experimenting with all the BOX settings, I found that I was able to get a perfect picture only by using the YCbCr709 HDMI color setting on the XBOX.
So now I have a perfect picture (or so I thought).
I then tried cables 1 and 2 several times. Still no picture period, but cable 3 works great.....until....
Games were beautiful in 1080P @ 60 Hz, but then I tried Zune Movies.
I quickly learned that ALL movies and videos would not play back.
When attempting to view movies I would alternate between snow, a pink screen with a message to contact Zune XBOX support, and then a peek at the movie with the "SCHD Link Restored" message at the bottom of the screen.
So basically every 20 seconds you get a peek of about 2-3 seconds of the video. We had purchased a rental download of the Disney Earth movie and could not watch it.
As far as I knew 1080P was 1080P and games and movies should have the same signal but apparently not. I'll leave it to more experieinced video experts to speculate on why games play fine, but movies do not, but I am baffled.
The sum of all these events leaves me with several questions. Do I have a bad cable (I am thinking no since all work fine on blue ray). Do I have a bad HDMI connector on the XBOX? Why does only 1 of 3 HDMI cables work and why can I play games but not watch movies.
Hopefully someone can find some logic in this episode as I am so far unable to. Thanks!
