Hello all, It's been a while since I've posted here. I got out of the Home Theater Stuff since I went back to school and moved into an apartment, but graduation is upon me. I once again will be a wage earner and I need a little help in spending those wages effectively I (and some friends - and they'll be asking me since I'm the engineer) will be buying new TVs. I'm looking at rear view projectors 60" and up that are either already have an HTDV tuner or are capable of accepting the input from one later. I've given myself the google.com refesher course - reading everything I can find. I understand the differences between progressive and interlaced scanning, and know of the multitude of resolution/framerate combinations. My best efforts at figuring out my next question via the internet have failed. Is the capability to display 720p a function of the TV itself or of the tuner/set top box or both? (Same question for 1080i.) How does an external tuner connect to the TV? Through proprietary manufacturer specific connections or through standard component inputs or computer type VGA? I have yet to find any sets that advertise that they display 720p so I'm guessing that it is more expensive to build a set to do this and it is a function of the TV itself. So what happens if you want to watch HDTV on ABC which I'm told broadcasts in 720p on a 1080i set? Is converted and then interlaced by the TV or by the tuner/add on box? Are there any native 720p RP sets out there? Any that do both? I'm trying to future proof (or indecisive industry proof) my purchase. Lastly, I understand that frame rates for any of the HDTV resolutions can be 24 or 30 or 60. If the manufacturer claims 1080i capability, for instance, does that mean it will display all three framerates? Thanks for reading!
