Good day, all...
I posted earlier that my LCD suffered from the "jaggies", ghosting and uneven brightness...
When I boxed it back up, I noticed a pretty large dent in the bottom of the box that I had not noticed before, so my LCD may have been dropped. So I returned it to Costco the same day and they actually still had one, so they exchanged it for me. I've been using the new one for two days now and I am very pleased with it.
I must say that all of my original problems with this LCD are pretty much gone. The brightness is very even (although I did turn down the brightness).
There are no "jaggies" when watching DVD's in a window, but there is still some at full screen. And as for ghosting, there is very little. Star Wars Galaxies looks great, but Diablo II does show some ghosting when running fast, as the whole screen is changing constantly. Setting the refresh rate at 60Hz seemed to help this a little. 3DMark2001 runs just as it should, with almost no obvious ghosting. Text (in 2D and 3D) is very sharp, even at 1280x1024. I can't believe what a difference there is, compared to my old 19" CRT.
I am now very pleased with this LCD and have no reservations about it now. My first one must have been defective.
