Well it would help, for a start, for this to be in the specifications 
they publish. I'm in the position of looking to buy a TV specifically 
to use as a computer monitor for my mother whose eyesight isn't what 
it used to be. My local big dealer has been quite helpful, allowing 
me free reign round the display models with laptop and cable, but 
it's a bit of a pain trying to figure out which ones have the right 
features - at one point I was hooked up to a 37" Sony which was 
"quite nice" although it was clearly still doing something to 
"defocus" the image. A friend works in their service department, and 
he's had no luck getting information from his technical contacts - 
"we don't have that information". So I've emailed Panasonic (one of 
the brands they do) thus :

I'm told that all emails go into a tracking system and their score 
gets penalised if they leave any questions unanswered - it will be 
interesting to see if I get any answer at all, let alone one that 
answers the questions.

Now if enough people ask these questions, they might start doing 
something. While I don't expect to ever connect such a source to it, 
I deliberately threw in question 6 to see what would happen :-)
