1080i is an input signal type. Any HD-capable set (i.e. HDTV or HD
monitor) can accept 1080i input because it's one of the 18 mandatory
formats required by the ATSC specification (

Assuming it's a fixed-pixel, high-definition display (i.e. DLP, LCD,
...), the TV will either be a 720p or a 1080p. If it was purchased
before July 2005, it's definitely a 720p. If it's a brand new model, it
might be a 1080p display. However, if it is a 1080p display, you may
not be able to use DVI (mine only supports 1920x1080 via VGA--the DVI
input will only take 1080i).
If it's a CRT, you might be better off sending it a 1080i signal, but
since it takes a digital input (i.e. DVI), it sounds like it's a digital
display type (=not a CRT). Also, 1080i might actually work better over
component than over DVI.
The model is a Toshiba 57H85C Rear projection TV. So far looking in
the specifications all I can find is suggested scan rates for HDMI
Input (1080i, 480p, 480i, and 720p) but nothing saying what the TV
actualy "is" (1080p or 720p). I guess I'll know for sure when I get
the cable if it actually works or not. If not I'll try a VGA cable.
Would you run VGA-HDMI or DVI-Component? or is it all dependant on the
signal? ... I'm still pretty green when it comes to this aspect of
computer based home entertainment :-) ... thanks again!!
According to Toshiba that's a 540p/1080i TV (CRT projection).

So, go with the HDMI cable and send it a 1080i (1920x1080 interlaced) or
a 540p (1920x540) signal (not 720p). It's probably not worth trying the
component inputs--especially if you like the picture you get with the
HDMI input. Also, you should probably check out Jarod Wilson's HDTV
section since (at the time), he was using a 1080i/540p HDTV (
