I bought a laptop and i dont think it has LED backlight - the white color has kinda yellowish tone and i think its CCFL. In my expericnce, LED has clear white or sometimes blueish. Also its not as bright as other LEDs i saw. The thing, on manufacturer page ASUS, the panel is specified as LED. But the seller didnt have this specified in description, which i didnt notice.

Please is there way to verify if the panel is indeed LED or CCFL ? Any comments if LED can have this yellowish tone are welcome. Thanks.
