I tried this test:

Not sure how accurate it is. I see no dithering. Do you know of any other tests?
Just did this:

I just did the clock test, on this display, and my laptop's display...out of about 10-15 tests... highest was 51ms, and lowest was 31. Took photos at 1/2000" at 1600iso.
Not sure how scientific that is.
Just ran a Spyder4 calibration. Here is the advanced analysis I ran afterwards. No idea how accurate it is.

I got this one:

Honestly, I had no real "failure" issues with my 39" Seiki... only thing I disliked so much was 30hz, and the terrible sound output.
I got 1920x1080@75hz to work anything beyond that I get an OSD msg saying that mode isn't supported. When I do 2560x1440@30/60/75 It shows the screen but it's scaled to 1080. However, I'm still having issues of 60hz not sticking, so I wouldn't trust any of this as normal.
One other thing I...
What do you do that this would effect you?
Once I have my 30/60hz issue sorted I'll start testing other standard resolutions beyond 60hz. My 39" Seiki can do 120 at 1920x1080. Would be surprised if this couldn't do it.
