new Inspiron uses downgraded screen 262K color

Thread Starter 
I looked it up on the manual of the 1520 and 1720, they both indicate 262K color or 18bit color vs 16.7mill or 24bit on the older line. I need someone to check their panel when they get this. You cannot check it form any Microsoft OS, you will most likely need Powerstrip to get the panel info.

I've posted this on notebookreview.com but generally I find the posters there are pretty green tech wise, but then again over here, hardly anyone post anymore.

ALL notebook LCDs (including new or old Inspirons) have 6-bit panels, they can produce up to 262k colors, with dithering it can go up to 16.2 million colors. If you want 16.7 million colors, you have to get an 8-bit LCD, many high end desktop LCD monitors use these panels.

As far as I know, most modern laptop LCDs do not truly render 24bit color depth. I was under the impression that at least all the ones with the fast response times (for gamers...) show only 18bits of color depth. See here for some more explanation.

Dell is following suit with all other major manufacturers in using 18 bit LCD's which are much higher in availability right now. LCD makers have been pushing this for a while to sell more LCD panels at a lower price. They're doing it on the desktop LCDs too.

This only helps keep the prices of these guys lower, which is definately not a bad thing. And most folks can't see the difference when using them. If it bugs ya, The XPS line will most likely still have 24 bit screens.

I doubt that it ever did. Maybe Mr. Evil can fill us in with better info, but the issue seems to be that if you want fast response time, you go to 18bit. For a gaming machine, the choice should be clear. I bet that pretty much all Dell laptops in the last few years have used 18bit LCDs.

Almost all LCD are 18bit and have been for years. There are very few 24bit panels on the market. Most LCD tv's are 18 bit. The true 24bit panels are quite expensive (about double the price). The human eye can only see 4096 color at a time anyway.

Sigh, more myths based on an inaccurate understanding of research.

You can't say something like that without explaining...

yeah, seriously. But there's nothing for him to explain. 4096 colors? As sol said, time for 12-bit color!

I found some info. I stand corrected... The human eye in theory can see millions of colors but no one really know how many colors a person can see. Everyone's eye's will be different.. Thanks, Zyb

...errr....if you could only see 4096 colors do you know how crappy your vision would be?


The human eye can perceive millions of colors & has an equivalent 70 mega pixel resolution at the center of the iris (dropping to 1 MP around in the peripheral areas). Women can actually see more colors than men, and in general the colors are better defined...But that is a matter for a genetics forum.

I think the confusion stems from the fact that some older studies show that for particular shade of colors (blue comes to mind) that the human eye cannot distinguish as many shades of blue as are in 16-bit color ...however it can distinguish way more shades of green and red than are in 16-bit color....hence at least in part, some of the confusion (basically, the computer based 16-bit color is divided across RGB spectrums equally, whereas the human eye is more evenly divided and is much more sensitive to some colors than others)

though this has been revised, now they are only certain that human capacity to distinguish blue is less than red or green; there's apparently a lot of variation from eye to eye
