Xbox 360's 1080p Doesn't Work on Sony's TVs

In a post on the AV Science forum, the newly available 1080p High definition feature that has been made accessible with the Xbox 360's Autumn Update doesn't work with Sony's Bravaria line of Televisions (XBR2/XBR3). Here is what the post by the AVS member says:

"I just had the time to quickly start poking around with the 360 dashboard update, and I'm sorry to report that 1080p is broken on the XBR2 via both component and VGA. When I select 1080p in VGA, I get a windowboxed picture with tons of info cut off on both sides and a warning from the TV saying "Invalid Signal--Check Your PC Output". Over component, when I select 1080p I get a screen full of static for 10 seconds before the console reverts to 1080i.

Feh. Since the XBR2 is one of the most high-profile, wildely available 1080p displays on the market, you'd think MS' engineers would find a way to get the two to work together, but noooooo..."

Here's a link to the details of the Xbox 360 November update.
