i can explain why they hooked up THEIR tv's the way they did.
harddrive so they can rig it so the mitsubishi actually displays a true 1080p signal (through the firewire port only or usb or whatever is in the back).
75ohm coax is there to mimic a HDTV antenna and they're just using the tv's builtin HD OTA tuner to display a TRUE HD picture through their own feeds.
sets hooked up with HD satellite might be there to demonstrate to customers the different between hd and non-hd but the employees use it to watch regular tv thats non-hd.
in my opinion...but magnolia store is more like a car-show room to "wow" customers with expensive stuff...then an actual store, but the employees a lot of times(in the chicago land area), have no idea what they are talking about and are cocky as hell.
i'd really like to see samsung's new LED light dlps that are comming out soon. LED lights produce a very good lightsource(great whites)...and add that to the 1080p resolution...it'll make a good rp tv with good viewing angle.......but its just not out yet for me to check out.
Most of you know, Iam planning to upgrade my old Sony 3 tube monster, and after a week of shopping I'am readdy for the nut house, Here is an example Went to Frys They had a 73" mitshibi that was jawdropping looked behind at the set up and found it was hooked up to a computor, Also there cheaper set were fed with a 75ohm cable, some t.vs were hooked up to hi-def satellite and they looked nasty, Went to Magnolia they were displaying two front projectors that cost as much as a house IS THERE ANY 70" or larger t.v. out there that will give a stunning picture for $5000 max Also when I call lush budget home theater stores they just laugh at me when I ask about a projector for $5000
