1720 only 262K color???

This can't be right can it? I'm looking at the manual page 185, it says 262K colors, where as the manual for the 1705/9400 says 16.2 million colors.

Edit: The 1520 manual also says 262K color!!!
Edit: 1705/9400 is 16.7 million colors according to da manual.

 

Nope.. That certainly is incorrect...

 

I hope that is the case. 262K color as stated in the manul would imply it is an 18bit color screen vs the 24bit color screen of the previous model. Also, just in case someone mentions this, the number of color bits you can apply on your OS e.g. 16bit or 32bit does not mean your display will display those colors.

Until someone comes up with a reason this is incorrect, I assume this is an 18bit screen. Also, the battery charges up slower on the 1720, almost 2x slower at 4hrs vs 2hrs between the new vs old.

 

My older phone had 262k color lol. I'm sure that's incorrect.

 

Check the specs of the screen.. Use Everest.

 

262K color depth exist, it's called 18bit. I know we all want this to be incorrect, but come on, i want some help on concrete info.

YoJr can you help find this out? (he is the guy that gave us the specs of the 1520/1720 etc before it came out, aparently used to work for Dell).

For you gamers and regular work folks, 18bit will be fine. But definately not ok if you used you lappy for photoshop/ photography work.

 

no one here has the 1720 yet, so can't check. Someone has a 1520, I don't know if their screen is also downgraded 18bit. [edit: they are!]

And what is Everest? If it's the video game, no you can't check a panel's bit depth playing a game. You will most like be able to use Powerstrip.

 

The old panels were 18bit as well (it is actually referred to as 6bit because each of the three colors is 6bit). Screens use dithering in order to achieve close to 8bit color performance...and 6bit dithering screens can display about 16.2M colors. True 8bit panels display 16.7M.

 

Grey, sorry, the 9400/1705 actually is listed at 16.7 million colors. So what say ye now?

 

18bit vs 24 bit. I found this article and in it, there are links to 18 and 24bit color test chart. I can clearly see the difference on my 9300, which I assume to mean mine is displaying 24bit color.

16.7 million colors would typically imply a PVA/MVA/IPS panel as most TN panels (that's the type most commonly found in notebooks) are usually 6 bit panels.

I'd be more apt to believe that Dell made an error in their specs for the 9400/E1705.

 

That is not an accurate test at all. The LG L204WT that I'm using right now is a 6 bit TN panel and I see no banding in the 24 bit 'test'.

EDIT: Yay. 500th post.

Everest is a diagonistic tool.. That helps?
