The dark grey is mk4.

I have an mkIII, type 9760 with D10 panel.

From mkIII all the BV9's have integrated calibration camera's.

The MKIV has a slightly different system3 . These newer system 3's  have a different audio board. With a software update these can be upgraded with ALT techonology.

Older system 3's the audio boards can be replaced with a newer audio board.

mkIV and mkV have D11 panels.  

Can you tell us more about this:

I have an Mk.III model, which I love to death, and the only ALT I know stands for Acoustic Lens Technology, which is the design they use to distribute the sound horizontally 180 degrees in the tweeter below the screen on all BV9 models.

Sorry, you're totally right!

 

I swapped the ALT for AST!!! The Adaptive Sound Technology.

Ok, thanks for info. Is it big different of panel 10 and 11? And what about the color?

I cannot recommend buying a beovision 9. During warranty one modul of the beosystem 3 had to be changed. Now after four years I have to replace the plasma display for 2.500 Euros (see thread /forum/general-discussion-and-questions/beovision-9-big-bang-amp-olufsen-quality-service-issue ).

I have a MK II, perhaps the other models are of higher quality. I wish you luck.

Alsfeld, it was sad to hear. I have collected at the B & O since the 80's and love the products. Beovision 9 has been on my wish list long, and it seems that I buy an aluminum / black mk3. It's been used about 4000 hours. I hope I do not have the same problems you had.

In our familiy we have 2 BV9's.

Both without problems and working flawlessly.

Only the integrated BM5 gave some problems with the it's mainboard. But thats' an option not every buyer has. 

Hello Beobuddy. I want to integrate a bm5 in it. Have talked to someone who has done it in a same TV without problem.
