I'm a little confused as to what the bare minimum of colours has to be to get a half decent picture 
.
There is just so much conflicting infomation about lcd panel colours, I thought I'd ask here.
I have been looking at a panel that can display 2M colours and a contrast ratio of 200:1... is this panel any good for viewing films, computer etc... using a standard ohp?
A list of colours and picture quality expectency would be great!
Also what is meant my true colour?
Appreciate the help,
Mick

That panel you've seen at 2M colours and 200:1 contrast ratio will be fine - don't expect anything much better from old style projection panels.
IMHO, look for 1.2M colours as a minimum for lifelike video, and a minimum CR of 100:1

true color is 24 bits, that's 16.7 million colors (or so) 32 bit color is a 24 bit color image with an 8 bit alpha image.
Thanks for the info 🙂.... appreciate it.
Now I know exactly what I'm looking for its back to looking for a panel.

i dissagree with 1.2m colors being a minimum... if you look at a perfect fractal or something very colorful with a gentle gradient, you will see that 16 bit high color is already pretty fantastic, although when you analyse pics of a light blue fractal or similair with 16 bit you may see a strange computer effects compared to true color. you can compare the effect by switching from 16 to 32 bits on a good crt monitor.
18 bits is absolutely humungous amounts of color already and is not visible to my eye i am sure...
16 bits on yor crt now would be 64.5k colors, 18 bits would be 227.77k colors and 24 bits is 16mn colots. 18 bits is overkill already, compared to pixellation limitations. in games 16 bits is not visible at all i reckon.
32 bits is 8 bit alpha, which means that colots can be laid on top of each other at like 256 layers or something, is this right? it's purely a processing consideration, no actually visible on the screen tho. would have to read about it.

This is very subjective, meaning that most people will have differing opinions depending on thier tastes, hardware and application.
If you are serious about games, there is a huge difference between 16bit and 32bit (depending on the game and your hardware of course).
e.g. Splinter Cell (PC) at 1024x768, max all the details and shadows then goto the China level where there are lots of contrasting lights and fog. In 16 bit mode there is a significant amount of "banding" with light/dark color shade graduations and mixes where there isnt enough colours to make up for it. In 32bit mode all the color graduations are perfectly smooth.
Though, in truth... Most people wouldnt know what they were missing unless they actually compared it with a high end PC setup. I tend to notice it a lot more in slower games and flight sims where detail is more important. In fast action games like Quake3 and UT2K3, you're more worried about getting your head blown off then looking at all the pretty colors.
Not to mention the fact that unless you're one of those rare people with a perfectly "balanced" DIY lens/lighting/projection setup, you're going loose most of that colour goodness anyway.
Personally, I'd never go back to 16bit **shivers ** I need to justify that ludicrous amount of money spent for that damm video card with the 256MB RAM, Eight parallel rendering pipelines, Four parallel geometry engines, 256-bit DDR memory interface, hardware 2.0 Vertex Shaders support vertex programs up to 65,280 instructions with flow control, 2.0 Pixel Shaders support up to 16 textures per rendering pass 2x/4x/6x full scene anti-aliasing modes, adaptive algorithm with programmable sample patterns, 2x/4x/8x/16x anisotropic filtering modes and under the mother of all air cooled GPU heatsinks. 🙂
what you do have with low bit is a placebo effect of what you think is better.
look at it this way... a dvd is about 800 600 pixels, which is about 480000 different colors at any one time... i reckon no one can tell the difference between 18 bit dithered image of blue shades of sky compared to 24 bit looking on a dvd, most artifacting comes from mpxellation.
i dont know if many tests have been done on games, i know that you can see big bands on 16bit with a synthesised image of shades of blue, only if the left side of the image is only a tiny bit more bright than the right side of the image. i reckon that 18 bit dithered is approximately as good as 128bit - 160bit audio, and i dont thnk many people can tell the difference in normal applications.
i'll definately get a true color tft when the technology has advanced some more, particularly for higher res. at the moment about half of tft are 18 bit. the only thing i care about is brightness of colors and anisotropic on the radeon 🙂
i would be interested in the results of a test between 16 bit and 18 bit and 24 bit, to see if anyone could tell the difference, and if so when. i think that 99 percent of the time it's invisible. especailly at 1024, i cant with a recent trinitron 21" and ati ramdacs. and this is by walking around and looking at surfaces.
the only way i can see a difference is with fractal programs is with fractal pictures. i beleive you about splinter cell but i reckon for smoke at 1024, 4 times more colors and pixels that are intermingled rather than banded (dithering) 18 bit is in no way a compromise in real life.
only way to know what i real is with a test... ez

i thought i might post this considering this has to with colouring its a controller chip for my lcd with the specs, it states that its 18bit colour with 24bit quality so maybe the majority of the newer lcds are like this, hope it helps to sum up some lcd intersts regarding colour and how they work or are driven.

hehe.. I'll be nice and instead of rehashing this 18bit vs 24bit debate here again, I would refer everyone to Rapsac's post here and complaints about the BenQ 18 bit color..
http://diyaudio.com/forums/showthread.php?threadid=20088&perpage=15&highlight=&pagenumber=1
I haven't seen the BenQ myself though so I cant comment but my friend who has one at work says that the tearing from the dithering is noticeable in 32bit mode when playing fast colourful games like UT2k3 but not really noticeable in movies. This was not present in the 24bit(supposed?) CMV1515 I ended up getting that he saw.
Most people here seems to be in agreement though, get 24bit with a 300:1 CR+ and <25ms response if you find it!! Otherwise the difference in 18bit is marginal at best. Its prolly more important to consider that the BenQ is one of the easiest monitors to disassemble at the moment.

well i think that he is probably confusing pixellation for color tearing... i reckon i should ask some friends to see if they can guess the which is 16 and 32 bit on the trinitron, i have 10/10 vision and for a moment i thoght the the bordeaux was brighter and less rusty and that 16 bit looked less organic, but the more i tried to see if there was a difference the more it looked exactly like 32 bit... ut2k3 that is.
i know what you mean that it sounds like a major compromise but really i dont beleive this story for a second young man. in fact i think that is very naughty.
i weighed up getting the cmv as a first board, it is way cheaper. but if cant reform into a panel shape, only a l, i'll wait up.
on a high def monitor, it's tru color all the way 🙂
