Is this normal on a VW10HT?

    I was checking the focus on my VW10 earlier, and looking at the box test pattern, the white lines have a blue shadow to them. It looks like it's out of alignment. Is this normal? The picture looks fine when displaying normal video.

    This is as close to focussed as I can get it btw. It just looks blurry on the picture because I can't hold the camera still enough!

    I suspect you have just noticed one fo the great fallacies of fixed pixel projection. That it has perfect convergence.....it doesn't. Well multi panelled devices generally don't.

    It's quite likely that the blue panel is slightly out of alignement.

    Thanks for the quick reply, Gordon. I was a bit confused because I'd heard LCDs were meant to have perfect convergence, but couldn't see why that would be so when the Sony has three panels.

    Can it be corrected, and if so, is there any point? It's only close up I can notice it really.

    I think they will just say it is within spec. A one pixel mis-convergence of blue shouldn't be an issue at normal viewing distance.

    It is caused by physical mis-alignment of one of the three LCD panels. They CAN be mechanically adjusted. Honestly, I wouldn't bother, though. You're not likely to see this in normal use, and you can have comfort from the fact that it is probably much closer than the average CRT setup and will never drift and need recalibrating.
