Well, the Dutch Benq office relayed my email to the factory and this is what I got back:
___________________
For 15" LCD, typically all the monitor makers apply "6-bit + FRC ".
FRC means "Frame Rate Control", which also called the "Dithering".
Different methods of FRC can simulate different numbers of color, from 16.2M to 16.7M, based on different algorithm.
Those
If the panel is 6-bit, the panel itself can display below number of colors.
2^6=64.
64x64x64=262,144 colors.
So the panel spec from LPL is correct.
The efforts to make color simulation is in chipset side.
Again, all the BENQ LCD can announce 16.7M color with Dithering.
___________________
This quote from the mail was all the explanation I got, and the Dutch office seem to think that this is sufficient to end the discussion.
I replied that a 16 color panel with dithering can also produce 16.7M 'colors', but I guess I wont get any response.
So, what does this all mean: (in my 'humble' opinion)
- Let me start by saying that dithering is no substitute for real colors; at best it lowers the resolution to display the 'missing'/'interpolated' color, which in the case of the FPP577 means resolution drops from 1024x768 to 256x192.
Also it is impossible to get any single pixel to produce 16.7M colors
- Benq claims 'For 15" LCD, typically all the monitor makers apply "6-bit + FRC'. This is food for thought.. of course Benq isn't the only brand to use the low budget A4 type panel, so other brand monitors are out there that also have 262200 colors instead of 16.7M. The problem is: all specs I have seen on various brand websites ALL claim 16.7M, NOT ONE admits to use 262200 colors+dithering or FRC (btw, FRC does NOT work on this panel)
- Benq does not seem to think any further action is neccesary, and will still claim the 15" 557 to have 16.7M colors an all product specs.
- The specs on various websites cannot be trusted. It is not possible to buy a 15" TFT with 16.7M colors unless you can dismantle one in the shop and lookup the specs of the used panel.
I wont take this up my rear pipe like this, still considering my options. As a start I've informed the wholesaler of my monitor, they already said they will discontinu their sales of this type at once, because they will not sell products with misleading specs.

Rapsac,
Do you know if the same holds ture for the new s type screens from Benq? I was specifically looking at buying the FP 567s or the FP581s since they have 16ms response times. Do you know if they only have 262K colors or if its real 16M.
Thanks for any info.

I have seen the specs too, but its impossible to say anything about the # of colors until someone buys one and opens it up.
hi...i am looking for the LM150X05 panel...any idea where i can buy one...this is mine....
seems the B3 is also 16.7 Mil
seems the B3 is also 16.7 Mil
An externally hosted image should be here but it was not working when we last tested it.

i think the FP581 is only 262 cause in windows mine shows as 32bit color under settings...
Compared to paying 500$$
My comment is simply this, with the benq, at least you can expect fast response time(frame rates) at 1024x768 res
and the fact that there's no ribbon cable is the knockout punch when it comes to this solution
and that's comapared to paying 500 for a used lcd projector panel from someone on ebay
anyways, i think we'd all like to see a good DVI connector lcd with true color(without a ribbon cable)
I think the samsung models are beautiful lcds, so hopefully we'll find the perfect match, but until then, give me a benq, you'll see a happy camper
