I basically had to teach them that there are 2 different panels (three including that second samsung?) that comes with the 1907. be sure to explain to them that when you say "panel" you mean the actual lcd, not the 1907 exoskeleton (yea.. they're that noob). I told them that mine was an AUO with 500:1 ratio while my friend's was a samsung w/ 700:1, then i went on about saying that they sent me the "wrong panel" because AUO's site claims that its 500:1 rather than the advertised 700:1. After some haggling and BS'ing, eventually they will file an exchange, they will send you a new monitor, and you return your old one with the new box you get.
heres hoping the second one is a samsung I will prob get it early next week.
PS. I played about 4 hours of HL2 single player and found the quality on the AUO to be acceptable and clear.. like I said before, I had to try hard to cause ghosting to see it. so i wont be THAT ticked if the 2nd one I get isn't a samsung =P
