LED Backlight Color/Contrast Weakness

post #1 of 4
Thread Starter 
Hi all,

A couple of days ago I made the switch from an old Acer 22" CFFL screen to an Asus VS248H-P 24" LED screen. I began to have some trouble with trying to adjust the color settings right; everything just seemed a bit washed down; a bluish-white tint seemed to envelop everything. I couldn't get it to be nearly as "warm" as my CFFL monitor. After a couple google searches, I'm no longer sure that the Asus itself is actually the issue. Others have complained about the exact same thing after switching to LED from CFFL monitors, leading me to believe that LED monitors simply cannot display colors as well as CFFL monitors, a concept that I haven't particularly heard before. Is it perhaps just a change that you get used to, not necessarily a disadvantage? This difference is made very apparent in one of Linus's videos:



My main question is: is there any merit to this concept that LED performs less adequately color reproduction-wise, and if there is, would this still be present in more expensive TN LED panels like the BenQ XL2420T or Samsung SA750/950?

Thanks!

actually with LED cinema display you wont have that much of difference yes you will have vivider color and cooler but only is this in the colors difference but the main difference in dark scenes most monitors will blind you in dark scenes like in caves video's but with higher contrast ratio ( LED advantage ) if you will take LED display take 1+ million contrast ratio to have lighter scene in dark videos .

WLED backlighting very often produces a cooler temperature white (more blue than yellow), but they are typically more capable of wider gamuts than their CCFL counterparts.

Unfortunately I have no experience with the display you've bought, but I noticed this floating around which is an ICC (color space) calibration for that model of monitor (but perhaps crucially, not yours) which you can always try out.

Remember that the ICC profile simply makes the display more true to a standardized color model, and not necessarily 'look better' biggrin.gif.

As for the contrast, the only solution is to turn the brightness down. Poor zero states and backlight uniformity are inescapably unchangeable aspects of the hardware configuation of a panel.

Yeah, I definitely notice the blue focus. I guess it's just something to get used to after 5+ years on CFFL.

I'm currently using that color profile actually, although I honestly can't admit to have noticed a change when I applied it.

Thanks for the reply.
