A lot has been said about the ability of a device to accept 1080p input for the past year or so and CEDIA delivered on the manufacturers' promise to provide 1080p input on their new 1080p sets. While a 1080p display must, of course, be able to construct the 1080p image from lesser sources if there is no 1080p input using its internal scaling/deinterlacing, etc. I've always taken the position that the best way to do this is to use an external device for the scaling, etc. In this way you always have the ability to upgrade your scaler/deinterlacer without having to upgrade your display. In fact that's a major reason I chose the HP MD5880n over the Sony SXRD RPM last year and I've not been sorry. The reason is that in the short span of a year my current scaler, a DVDO iScan VP30 has undergone two (!) major upgrades and more are promised. First, early in 2006, DVDO introduced a daughterboard for the VP30 which greatly enhanced deinterlacing of 480i source material (I installed it and it performs as advertised) and now at CEDIA they were demonstrating the VP50 which not only enhances 1080i deinterlacing in state of the art fashion but also will add many other features such as PREP (reinterlacing "forced" progressive sources so that they can be handled properly) and many other things. My point here is that without outboard scaling these upgrades could not be accomplished if your display must use its internal scaling.
Now along come new, inexpensive 3 chip FPs with 1080p input and the use of outboard processors becomes even more attractive. While I'm most familiar with the iScan line, there are also other companies which offer scaling/deinterlacing products that can accomplish the same goal for those who want to extract the last drop of performance out of their displays. Here's a place to discuss what I saw at CEDIA in this regard.
