Mitsubishi wd82-738 geometry ?

Ok so I just bought a brand new 82 738 for a steal over an 838 and i previously had 2 73" diamond series tv's. I hook my computer up to my tv via hdmi and use it as a monitor for gaming, homework and whatever else I use my pc for. Now to fix the overscan issues I resized my desktop (my computer has a gtx580 sli setup) to fit the screen perfectly, but there are places on the tv and in the corners where the edges are not straight when I move browsers around. I dont want to say warped, just bowed areas. It did this with the 73's but 82 is soooo much more noticeable.


As a computer guy Im pretty good at fixing things and Ive been in the service menus and Im kind of lost on trying to straighten out these lines. The tv has a usb port and I was wondering since it will let you reset the changes you made, can you load some sort of geometry setting that way? Like someone elses calibration loaded on a usb drive to try on the tv?


If not am I being to unrealistic by wanting these bowed areas straight? And if not Where in dallas would I start to find someone to do that and how much would that cost?


also I had one more? Would a new blub look better than a blub with about 4000 hours on it. I was thinking about this for my 73.


Thanks guys !
