The internal grid pattern is no good because it is a two pixel wide pattern. This masks convergence. A single pixel grid with single pixels inside the grid boxes, like is provided on the AVS HD 709 disc, is excellent to check convergence.
You can download and burn the disc for free - it is provided here in the forums: https://www.avsforum.com/avs-vb/showthread.php?t=948496
Put up the single grid pattern (its under the misc. patterns section). Look at it from your normal seating position. It should have NO visible color tinges. Then walk up to the screen and check. You'll see some misconvergence. A tiny bit is fine. Is it uniform? How much is it off (1/4 pixel, 1/2 pixel etc). Now look at single pixels displayed in the boxes. Does it look like a single pixel, or does it look like a grouping of a red, green and blue pixel? The wider the grouping, the worse the convergence. Please let us know what you find.
Its a great disc to have no just for convergence but it has other very useful tests as well, such as testing interlacing , motion handling and more, not to mention great patterns for setting the basics.
There is also a radial pattern that is exceptional for testing sharpness and detail resolution. Its under the misc. patterns. Pull it up and look at it from a distance. How far into the middle of the pattern can you see before it gets blurry? Is there any color fringing or "tint" to the image? It should be black and white only. This is one of the most revealing torture tests I've seen yet for projectors. For example, this pattern on the RS1 shows a lot of red and red. In the RS20 it shows it too, but less so. And on the RS50...?
