I can see it pixelate when very close but not sure when the transition happens. Any ideas / thoughts from your prior experience with such a Monitor? Can hardly make out.

The dot pitch is very small on them and it's difficult to see the pattern. But if you compare it to solid grey, you will notice a slight difference. I had one of those monitors.

How do I get this to work? I cant really tell if this at all has a pattern? I have a 30″ LCD 2560 x 1600. How do I get this to work?

I cant really tell if this at all has a pattern?

The area being used for the test pattern is composed of alternating light and dark pixels. Each pixel has an opposite one in tone above, below, and to each side. Similarly, each pixel has a like one in tone adjacent to each of the four corners. Edge pixels are not surrounded by neutralizing pixels. For the edge pixels to appear as a straight, alias-free line would be the "merging point" of the black & white pixels multiplied by the Rayleigh-limit factor (1.22). So, if the test pattern appears grey at some distance, the jaggies begin to disappear at 1.22 times that.

This is a very good point made by Badvok. Do you have a response? >> Have you noticed that although the main area of this pattern blurs and goes grey as you increase your distance you can still perceive the edge as jaggy?

This is a very good point made by Badvok. Do you have a response?
