I belive that the only tv's that can display true high def are those with 9" crt's. There are no consumer direct view tv's or 7" crt rear projection tv's that can display the full resolution of HDTV. They can recieve it, but can only display around 800 lines at best.
The rear projetion tv's capable of displaying all of the lines in an HDTV broadcast are (as of now)

The Mistubishi WS-73905 73 inch 16:9
Philips 64PH9905 64 inch 16:9
Samsung HCJ655W 65 inch 16:9
Zenith IQB64W10W 64 inch 16:9

all of these are in the $9-10,000 range as 9" crt's are expe$ive

There was also another 9" introduced by Panasonic, I belive, at the CES.

It seems to be somewhat of a secret that only 9" + crt's can display true high def. And, the only direct view tv's that are capable of full resolution are professional moniters in the $20,000 plus range....
