Samsung DLP or Panasonic LCD (Projection)

[Kaiser Sosze]

I have an added question since I 'm in similiar market,

In comparison to a HDTV rear projection TV, aligning the Convergence is a pain and always becoming unaligned when the set is moved or some other affect,
1) Projection DLP and LCD- do they need to be aligned with the convergence grid?

I could not find the option on my friends Panasonic DD LCD projection, I'm assuming they don't have to be, But am unfamiliar to the DLP

Having a tech come in every so often to fix it using the remote for $75 is so fustrating

Thanks

No convergence adjustments are necessary with LCD or DLP. It's strictly a CRT thing.

Is auto convergence on new crt based projection tvs usually acceptable? If not, how difficult is it to do without experience other than basic tv setup with an avia disk, and how often does it usually need to be done?

It depends on what you mean by "acceptable." People have different standards. The effectiveness of auto convergence can also differ from set to set. Even though the automatic variety usually gets you into the ballpark, a manual option is always best to have for inevitable finetuning to one degree or another. If a set doesn't offer manual convergence, or offers it only in the service menu, I would consider it at a disadvantage. Convergence isn't hard to do, but it can be time-consuming, especially if a projector is generous enough to provide more than nine measly points. If you wear glasses, and bifocals, seeing clearly is hard enough, but attempting to align three colors on a crosshatch can be just enough torture to send someone screaming to a fixed-pixel display, though many people aren't too fussy, and others don't mind the extra work, given the rewards. A new set should undergo convergence within the first month, and then every three months or so thereafter, unless rainbows begin to propagate on screen sooner. If you move the set in any way shape or form, you'll probably need to converge it immediately. Going out of convergence is an occupational hazard for CRT RPTVs and front projectors.
