Yeah I mentioned it in my first response to ya. Why would linux be "most of the problem"?
Less driver support vs M$. More chance of issues. I just took a stab at it. It's logical to figure less popular O/S's would have more of a chance of having compatibility problems.
LCD's are best for pure digital sources: PC's that can provide 1:1 pixel mapping. They are the worst
for analog or anything that doesn't map correctly which includes SD
DLP's are best for a mixture of sources: compromises for digital and analog.
Plasmas are best for movies in a controller lighting environment. Bad for PC's due to burning and not great for analog.
My 2007 Mits has a slight underscan which isn't too bad after I change the default 1920x1080 to 18??x1000 (can't remember the vertical resolution). It's better than overscan as Jim pointed out. I wouldn't call the designer a genius, just someone that knew what he was doing.
BTW, it's not "silliness". If all you are going to use the set for is a PC monitor, LCD is fine. If you plan on using it for anything else, I suggest you re-think your decision. I have thought about upgrading, but the two other choices are not all what they are crack up to be. Flat panels don't impress me just because they are "flat". There are plenty of trade offs.
