I'd gladly help if I had a camera........ I went to BB, but the idiot "Salesman" said he wasn't allowed to connect a computer to any TV.
Grab a 32" from BB for a month of use and return if you dont like it. Nothing wrong with that, lots do it. If the big stores didn't expect you to make use of their 30day money-back offer they wouldn't make it.
Personally I agree with your caution, we work too hard for our money to toss it away carelessly. Good luck with your quest for "very big PC screen". 32" is really a nice size, not too big not too small, maybe its the 'sweet spot'.
Btw, this 32-inch Sharp D62U that I presently have is an 'open box' item that CC had on store shelf for 889. For that price I couldn't pass up "giving it a try". Here's what I have found so far....
Besides its excellent performance as a huge, hi-resolution, PC Monitor----- I have also noticed (during my "game playing time") that it seems plenty-fast in Games. So, maybe I wont be swapping it for the more expensive 32-inch Sharp GP1U 'gamer' model after all. Well we'll see, time will tell.
