I don't agree that Sony is any better than JVC or Sim2 in out of the box convergence and in fact Sim2 may indeed be the champ, as it should be considering their cost compared to the others. This is especially true for the models that allow physical xy adjustments of two panels at the factory and provide a tightly toleranced block for Y axis stability.
As I have continually posted full pixel shifts have no adverse effect on PQ in real life or test pattern wise, justing losing a line at each end. So with regard to a Sony an error that is over ten (the steps avalable in a subpxel adjustment), one can just shift in units of ten to reduce the error to +/- 5 or less before adjusting the subpixel further to hide the error at a cost of sharpness and resolution. +/-5 is the absolutely worst case with the Sonys after full pixel shifts which aren't deleterious.
The JVCs subpixels adjustments are in 16 steps between full pixel shifts. No different than the Sony except for finer adjustment steps, the worst case after full shifts would be +/- 8 which while being numerically higher than Sony's 5, are exactly the same in effect, half a pixel off. If you are 1/2 pixel off on either machine after adjustment for full pixel you have the worst case scenario and zeroing the misconvergence from there will have the worst case impact on sharpness and resolution. For what it worth, this is quite liveable correcting it or not, particulary with a 4K machine of a 2K machine with e shift.
Out of the box convergence wise doesn't really mean much. What counts is after warmup. How she performs after warm up or foreplay.
Then you can adjust it to hide any convergence build errors errors from your eyes. Once again, after full pixel corrections, the worst case you can have is a half pixel correction and then you can consider how much of a half pixel you should shift trading off the loss or resolution or sharpness. Most will not notice the losses and will just shift to 0 out the error. And indeed at 4K, zeroing it out won't be noticed one way or the other with 4K a few feet from the screen.
See you all tonight. Have to work today.Edited by mark haflich - 12/11/13 at 2:55pm
