The answer of course is 3 (dedicated RGB) DMD chips but that wouldn't be
cheap and there's not even too many movie theatres with that technology
yet - according to my 'digital source'! (Oldest son!)

All Digital Cinema projectors use 3 DMD chips, but it's certainly true that
few cinemas as yet are equipped for D-Cinema. Not only is the equipment
expensive, but there are relatively few "films" available in digital,
compared to good old 35mm film.

If you want summat to nag away at your brain - think of the *2.1 MILLION*
mirrors on a 1080p DMMD chip twinkling away all the while you watch the
latest blockbuster:

Bothers me - I'd sooner not be reminded of it....


You mean how much it's going to irritate when just one of them sticks.


At the risk of tempting providence - we haven't had a single instance of a
'stuck mirror' on any of 6 different DLP projectors in the last 3 years.

Even better is that, according to the 'family AV expert' just now, no-one
has mentioned anything like it on the various AV forums in the same period -
IOW, it's a non-issue. Visible effects of dust on LCD panels is a common
problem, on the other hand!

I am also advised that if a mirror did stop working it wouldn't be out of
action 100% of the time and it would supply the colour range that would
apply to the appropriate *on or off* state of the affected mirror.

The reality is not to worry about it - for instance, I can usually go about
10 minutes before I have to get up and ping the screen to shift the various
'movie moths' that start to appear about now and last throughout the summer!
(Note that *I* have to get up to do it!!)

Sorry, that isn't very well-worded - it is the screen pixel that wouldn't be
out of action 100% of the time due to the 'stuck mirror'!

(Not sure that's any better wording...??)

Yup. And ones that don't have defects.

Are you talking home recorded ones or 'factory'? Can't say I've had
problems with mass produced ones - but home recorded seem to have a
limited life. Although it seems to depend on make of blank.

CDRs really. And I don't know if it's the make of the blank alone ( I
usually use 'name' ones of some reasonably quality reputation ) or the
drives pack up early. I've thrown out more CD drives than any other
piece of PC kit.

I've had loads of factory ones, about thirty CDs purchased in the
eighties manufactured by PDO. Thankfully they replaced them :-)

The first generation of CD drives certainly seemed to have about a 3
year life.

A lot of my failed CD-Rs date from days before I realised that burning
at the manufacturer's maximum rated speed was NOT a good idea. The
better burn utilities prominently feature a choice of burn speeds.
Unfortunately many of the consumer-aimed programs hide this setting.
