6bit Panels = 16.2M colors, not 16.7M, correct?

[Acert93]

I am looking at the L90D+ 19" LCD from Hyundai. I am thinking of buying 2 of these TODAY. But I am a little confused...

I THOUGHT it was an 8bit (24bit) panel because (a) Hyundia, Newegg, Chief, Tigerdirect, and so forth claim it is a 16.7M color panel and (b) the reviews state it has great color reproduction.

Yet I have read a few posts saying it is a 6bit (18bit) panel. So what is it? And anyone who has this panel, how is the dithering? Is it noticable or something you really have to look for?


As a side note for anyone who owns this... how is it in portrait mode? I have heard raves and boohs (shadowing/narrow view angle). So which is it?

Quick feedback welcome as I want to order these this morning if the colors are fine (6bit or not). I do webdesign and a little photoshop, so I want good color but very small dithering wont affect me much. Thanks!

I was under the impression that 6 bit (per channel...18 bit total) panels were 262k colors, not even close to the millions. 2^18 = 262144, 2^24 = 16777216

Says 16.2M on thg.

By definition, a 6 bit panel displays a maximum of 262,144 colors. (You're right; it's an 8 bit panel.)

6 bits X 3 colors = 18 bits; 2^18 = 262,144 colors. (Also, (2^6)^3, or 64^3.)

8 bits X 3 colors = 24 bits; 2^24 = 16,777,216 colors. (Also, (2^8)^3, or 256^3.)

The LCD Manufacturer has 16.7M:

The people who sell it (Newegg, Chiefvalue, Tigerdirect) all say 16.7M also.

So Toms very well could be correct, BUT my question then is: Is this false advertising? I had read that 6bit panels, with dithering, are usually rated as 16.2M colors (as Tom's seems to point toward). VERY confusing.

What made you think it was a 6-bit panel?

That's strange, how are they getting 16.2M?

Quite a few posts in this Anandtech thread say it is 6bit:

And While the manufacturer/retail info indicates 8bit, the review at THG indicates 6bit by calling it a 16.2M color display.

I have no clue what it is Just trying to find out before I plunk down almost $750

Thanks for all the feedback btw.

They manage to claim 16.2m colors by including the so-called colors created by dithering. It's marketing B.S.

Yeah, I got the much. The question is how did they go from 16.2M with dithering (~200k real) to 16.7M colors?

That 500k jump is more than it natively displays and is misleading because it indicates it is a 8bit, not a 6bit, panel.

I should be getting mine soon, and will compare the colors to my 21" Trinitron.
