Resolution difficulty
What you need to check out is whether the LCD tvs actually accommodate the DVI signal that you get from a PC (believe it or not, there are many that do not, despite the fact that they have a DVI connector, it is not intended to be used with a PC), and whether it will resolve the computer's resolution.
It sounds weird that a DVI slot would not work with a PC, but that can be exactly the case. Do not be fooled by salespeople that don't know the product, do some research online to find out first. The reason being that the refresh rate that the DVI connection was made for in TV sets was to accommodate a HD signal. That refresh rate is anywhere from 40% to 50% of a regular computer monitor (which is why it will not display). Also, even though the LCD may be 1366 x 768, it may only display 1024 x 768 or some other derived resolution that is not native. That is why text, etc can appear blurry on these screens. There is no quick fix for resolving this and unfortunately the Mac mine does not have dual-dvi slot to drive its 30" screen, so you'll need do your homework on this.
