I have an x800 which is pretty much the same card.  I have not tried 
getting 720p or 1080i from the TV out.  However, if you have the 
component out connector, normally a bright red connector provided by 
ATI, it is supposed to be able to do HD.  I know I hooked up the 
component out connector in windows and in the ATI driver it detected 
that I had an HDTV setup.  I switched to DVI or vga though for this 
one.  On the x800 and probably x850 therefore, the 1080i looks like 
crap.  It was much nicer looking on my 9700pro.  720p is fine.
One thing to check, your TV might have component input for SD (for some 
DVD players and such) as well as for HD, but it cares about which inputs 
you use of course.  If you hook your ATI component out to the component 
in on your TV that can only do SD, then you aren't going to get 
anywhere, and typically it would max out at 1024x768.  It could be only 
able to 800x600 in your tv though.  On my TV the SD component in will 
literally take no resolution other than 640x480 from my computer 
(probably would take 720x480 didn't test).  I know on my TV it has a ton 
of composite, svideo, and component inputs for SD, and one component 
input for HD, and it's important which component input I use.  Actually 
makes me wonder why the heck my TV has so many SD inputs and only two 
for HD.
