C'mon Charlie,

You can't win a debate by getting into goofy definitions...

You said 3 chip systems must have convergence problems and they must have adjustments to the convergence.
This is wrong and I was just trying to explain to you why they need no convergence EVER. If you want to nitpick what I say (which was only meant to help you understand), then I'll just leave it at you're wrong about 3 chip convergence problems.

Now you ignore this FACT and get into some dim playing with definitions of the word 'perfect'. That's just sad you sink so low trying to make yourself feel 'right'.

"Whether they shift an amount that is significant I couldn't say, but to say absolutely something is perfectly aligned (hint - not possible) and never moves is silly."

Yes, nothing's perfect. DUH. At an atomic level everything's shifting. Thanks Mr. Wizard.

Let's stick with the'real world' aplication though ok?

My point remains unchanged... 3 chip systems have NO convergence adjustments, because they have NO convergence problems. This is 'perfect convergence' in 'real world' terms since you will never see the fringing error.

"Now I've not examined an accurate drawing or done any math to see whether it's likely to be 0.1 pixel or 0.0000001 pixel error in the worst case, but error will be present due to unavoidable variations in manufactured parts."

As I already said... if the original chipset is perfectly converged it won't change. Obviously flaws in manufacturing will happen.
Those flaws don't get used though (or you can tell a chipset's bad if it does get used). Either way, your 'point' is pointless and you're just grasping at microscopic straws.

Just admit you didn't know what you were talking about and drop the convergence subject. You were just wrong. Pick a new detail to debate (...and to be wrong about -heh).

You're right about FP's, but then I made those points a few posts earlier. At least give me some credit by saying you agree with me before you just reword what I write ok?

"Actually the on/off nature of DLP is one of its' strongest good points to my mind, as accurate linear control of duration is simple compared to analog control of intesity."

So?
You make this point after my quote about DLP vs. GLV which is also digital . My point was that GLV is a more advanced version both technically and mechanically.

If you want to relate DLP to analog like CRT then I'll say...
CRT despite being analog produces a wider grayscale than DLP can (though DLP is getting really close as of late).
It's my opinion an all digital system will be better than CRT eventually, but we're still not there yet, and once there we'll still have to wait for it to get cheaper than CRT so we're a long way off from the death of CRT.

"This comment was intended with regard to the paragraph immediately preceeding it regarding color rendition. CRT phosphor fades (I'm told) as they age."

I thought you were still talking about convergence. I'll have to re-read that post.

Anyway, yeah I agree that phosphors do fade over time. It's VERY slow and over looong time though.

So I supose you then think a one-chip DLP wins in this respect then?

Well DLP color isn't digital... What do you think happens to that spinning color wheel that's being bombarded w/ a super high power/burning hot lightbulb 100% of the time when running?

Do you think the color wheel won't fade from this? It does.

It may in fact fade more than CRT does. I don't know which is worse, but both degrade over time yet last long. The color wheel has no 'real world' advantage over CRT here.

Remember the DLP's bulb dims over time too (and isn't uncommonly known to 'pop' before it's rated hours ...something CRT almost never does).

And color convergence problems due to a one chip DLP system is why many people (note- I didn't say 'all' OR 'most') have problems w/ rainbows with DLP.

Of course zero people have rainbow problems w/ 3 color systems like CRT, LCD, 3chip DLP etc...

I'm not sure what you're looking for in a display. Maybe we should talk about that?

Or maybe take my $3K 65" Mitsu. You don't like CRT I guess..., so tell me what would you want to make this set better in your opinion?

And I don't mean just tossing around 'specs'. I mean talking about points that will actually result in a better display for hopefully a better price.

IMO, CRT vs DLP is kinda like in audio speakers debating dipoles vs. monopoles or cones vs panels or ribbons vs. domes.
None are perfect, and some of it is opinion/preference, but speaker for speaker you can get down to 'real world' details and debate which elements are better.
