You absolutely cannot adjust convergence. What you are seeing is misconvergence and chromatic aberration. You can adjust the timing of the image on each of the three panels to hide the misconvergence and chromatic aberrations caused by where the image is going through the lens and exiting to hide these two thingsfrom you seeing it. Generally the non uniformity of the why a grid composed by the units feable attempt to produce a blue, green, red grid overlap is caused by chromatic aberrations. The colors being uniformly off is caused by panel misalignment at assembly and the tolerance of such deemed acceptable or non acceptable by Epson and the effectiveness of its quality control to reject any unacceptable level of misconvergence. By using the electronic timing adjustments labeled for consumers as convergence adjustments (all manufacturers use this misnomer) resolution and sharpness take a BIG hit if you making any adjust other than by full grid lines. Adjument by a few tenths of a pixel if use sparingly (globaly and perhaps in a few places) may have a net benefit, anymore and its a big negative0 but it keeps consumers from complaining and rejecting units because they think they have made the bad effects go away. bottom line use very sparingly and watch from a distance where you can't see the remaining misconvergence. If you have blue misconvergence remember blue is only about 7% of the total color contribution and ones eyes are very very insensitive to blue. Red and Green misconvergence are much more visable and that is why green is used as a reference to which red and blue are err converged.
