I've been considering upgrading from my puny little 27" for some time. I got a good deal on a used Toshiba 51H93 locally and I'm pretty excited about it I wasn't able to find a lot of reviews for this tv, but the feature set looks great (DVI, Firewire, builtin tuner etc). I have a few questions - - Adjustments: turn down contrast, turn off VSM, select normal color temp, and use Avia to adjust other settings. Anything else? - Calibration: once I'm confortable with my tv, I'll try and find a service menu setting and tweak it - carefully! I can't afford ISF calibration and I'm pretty sure I can live without it Any links for this will be helpful, e.g. Toshiba tweak sites. - This may be a simple question - if I use a set top box (Comcast hd box) then am I correct in assuming I can't use the tv's builtin tuners. And if so that means the PIP feature, program guide, channel memory etc in the tv is useless? That would suck. - I just got the Philips DVP-642 for progressive scan playback (and because it plays mpeg4/divx). How is its output quality? - Does this tv support 720p? I read somewhere it can upconvert to 1080i but not sure. - I have a HT to go with this. Where do people place the center channel on tv's with narrow tops like this one. On the floor? The Tosh will let me use its speakers as a center channel but I'd rather not since my speakers are all matched. - I have lots of stuff to hook up - replaytv, xbox, dvd, vcr, not to mention routing through a receiver, so I'm sure I'll have questions on that I know not to waste $$ on monster cable and usually buy Ratshack, but should I spend more on component cables? Any other advice on the care and feeding of this beast gladly accepted. Thanks.
