"The new models all incorporate a proprietary optical engine, which utilizes Sony's three wide XGA high-resolution LCD panels, one for each of the RGB signals. This results in a total of 3.15 million dots of resolution for a crisp and consistent picture across the screen and from corner to corner. "


does this mean that there will be convergence issues with this tv?

Yep, convergence issues have been reported with the GW and GWII.


It's hard to avoid when a three-panel system is used.

Just a couple of notes:

The resolution of this TV is not 3.15 pixels/dots, but 1/3 of that, 1.05 pixels. Each pixel on screen has a contribution of the corresponding pixels on the red, green, and blue LCD panels but the three colors overlap on the final result (on screen) and thus don't contribute separately to resolution. To put it another way, the screen is 1366 by 768 pixels, making for 1.05 million dots total.


Convergence with this type of light engine, where the beam gets split into 3, passes through the active elements, and gets recombined into a single beam again, is set by the factory. In other words, while it can be mis-converged, convergence will not change over time. If it is off upon delivery it's going to be off forever. If it's perfect from the start (if you're that lucky) that's how it's going to be for as long as the set lives. As far as I know there is no field-repair possible for convergence, this is a single unit and if mis-converged severely enough it just gets swapped out in its entirety. This in contrast to tube-type rear-projection TVs where convergence changes over time and reconverging is part of the periodic maintenance.
