I believe the same. I did adjust the convergence on my RS57 using a very minor global adjustments and finally various minor local adjustments. Convergence was perfect around the middle of the screen and gradually got worse as I got closer to the edges of the screen. I checked resolution patterns with and without the correction applied (it is easy to switch the panel aligment correction on and off quickly) and I saw no loss of resolution whatsoever, just sharper, more defined lines. Of course, the difference is harder to see with real video material, but the picture looks sharper to my eyes with panel alignment correction applied, and this is more obvious as I look closer to th edges of my screen, even with real video material.
BTW, I dont mean to say my RS57 had bad convergence from the factory. In fact, the whole center area of the screen had perfect convergence, and the lens (more than panel alignment) probably causes the slight convergence errors I see around the screen. No matter, JVC provided a nice feature to fix this, and to me it leads to subjectively improved perceived image quality.
