There was a noticeable improvement after calibrating, but if you're not photo-editing (which I sometimes do) it really wouldn't be beneficial. Colors are more natural now, but it's not as if I'm staring at a new monitor. Pakii, do you have any other monitor you can compare it to? Even grabbing your old laptop, or iPhone etc to look at the blues should provide a noticeable difference. Your photo and video looked like the blues matched. Also, would anyone that voted positively on their panel happen to have a place they can get a Spyder (Frys etc)? You could return it later or if you're so inclined and in the SoCal area it'd be interesting to test a "working" panel. I've compared 3 and it still bugs me that my panel may be faulty.
