I have been repeatedly looking at various LCD monitors and comparing their conector sets and known limitations, and I always come back to the Westinghouse LVM-42W2. I figure, every display out there has limitations (clouding, banding, overscan, black levels, whatever), but I can excuse a lot more on a low-priced display like a Westinghouse than I could on a Sony or Sharp, even if I wanted to spend that kind of money (which I don't).
Yes, there are new Westinghouse TVs coming out with built-in ATSC tuners, but the "W1-W3 series" is a known quantity at this time, and if a whole different set of issues arise with the "TX series", it may be too late to get one of the current monitors (with a factory warranty). For what I want (a display for casual watching, but at the highest resolution available, and with plenty of input options and adjustments), the 42W2 should be about ideal.
In my case, I live in California, so worst case if I have to send the monitor off to Westinghouse for warranty repair, at least they are in the same state.
