Anyone with experience or comment to make, been doing some homework and the technology looks fascinating. Also I believe Naim use a Sim (i think) set for demo's

My dealer had a sim.

Beautiful picture - 720P res, wonderful onboard scaling too.
Downsides are that it's a dark image, with a very reflective screen... if it was living in a room with well controlled lighting I reckon it'd have been the nuts.

Very funky when you get up close to them.... no brace of red, green & blue pixels... the way DLP works means the pixels are simply whatever colour they're meant to be for the image.


I've heard of DLP technology being developed using laser diodes for illumination rather than expensive (and not very long-lived) mercury lamps. Rumours have it that this may well make them very liveable. Would love to see it happen.

I have a 52" Rear Projector Mitsubishi DLP set and I and very happy with it. Not as thin as an LCD or plasma but at 14" it is fine for us.

I had one of those SIM2 RTX screens a few years ago for a short time. Eyecatcher exterior, expensive (lifestyle designer stuff like B&O), good video-electronics and parameters, glass front works as mirror too.

I gave it back because some problems could not be solved:
- The excessive noise: Big fan in the screen and small fan in the external connector box. The color wheel was noisy too, spec. in higher revs (ntsc 60Hz is louder than pal 50Hz). The small notebook fan in the box even kept on running when in standby mode! I had to go down on my knees twice and grope the back for the hard power switches to listen seriously to music. The dealer exchanged the fan in the box and fit some foam around the other in the screen. Almost no difference...
- Several digital artifacts. To mention only one: Look at something bright moving in front of a dark background. e.g. headlights in a tunnel, full moon at midnight with the camera panning, fireworks on a dark sky, ect. It looks like on an old graphic card with 32 colors.
Nothing I could or would accept at this price tag!

What I have learned: 1 chip DLP is nothing for me. They have to cheat too much in the timeline to get a picture. First they have to flutter the mirrors to simulate grey, then they mix the colors again sequentially with the wheel. In fast moving scenes, this double mixup falls apart! 3 chip DLP seems to work better (the few times I saw it in a store demo). But the price goes through the ceiling there. LCOS (Liqid Crystal on Silicon) based technologies like D-ILA from JVC or SXRD from Sony deliver artifact free pictures for less money.
As always - take a look for yourself. Your milage may vary.

Happy watching

I have found a few interesting links, which explain the differences in the technologies.

Thanks guys - very interesting technology

We are very happy with this......



55" Sony Bravia (model KDS 55A2000), rear projection SXRD (three SXRD chips, one for each Red Green Blue colour) purchased from Sony after John Lewis let us down, but eventually managed to come through - by talking Sony into price matching them!!

£999.00 - including the stand, free delivery, and five year warranty......

It's a full 1080P HD ready beast, but we've no HD source as yet.....

But even with Standard Definition dvd's via our Rotel the picture is improved over our last rear proj - the 50" 3-LCD Sony (model KDF-E50A12U).

Can't wait for the PS3 prices to come down though!!

Cheers,
Ali
