I can shift with cent Green R-G-B. with an external image but not with the internal patterns.

So if I have to adjust rasters with an internal pattern, I have to center green and
then converge Blue and Red?

The reason I'm asking is because I had set up the internal pattern to match my screen,
But when I introduced an external pattern the image was not centered and neither was the raster.

So I have the crosshairs nice and converged and when I went to shift the rasters,
I had to center RGB one at a time :-/

Thanks

The control you're talking about that moves all together is RGB SHIFT. That works only on the external source and not on the internal patterns because it's shifting the active image around within the raster. The CENT control is moving the entire raster, and moves each channel individually.

When you do the set up using the internal pattern, you're setting convergence and geometry for one frequency, which on the G70 is roughly 480p (unless you or somebody else changed it). When you're done with geometry and convergence using the internal pattern, tapping the memory button saves all settings only for that one memory location. If you then press and hold on the memory button, after a few seconds, the G70 will ask "save to all memory locations?" or something along those lines. That's what you do.

Then, switch to your external source(s), and tweak from there. It shouldn't be too far off... But, yes - you'll have to do a little fine-tuning of geometry and convergence with each different source that falls into different memory location (i.e. 480p, 720p, 1080i, 1080p). Shouldn't take much for each one. Just small, fine adjustments.

You'll spend the most time nailing down the internal frequency. Then save to all memory locations and spend more time perfecting the one frequency you'll use the most. In my case, that's my 1080p slot.

I was afraid of that.

It would have been nice if one could shift RBG raster like you can with RGB Image.

Well, typically you shouldn't really ever need to shift all three rasters at the same time. I can't really think of a time that the rasters would all be converged, but simply off-set, or why that would really happen.

Typically, you center the rasters (strings on the screen centers works well), do geometry and convergence for any/all resolutions you'll be using, and you'll be done. At that point, you should only need to use RGB SHIFT to compensate for the signal with slightly different timings from another.
