17.3-inches is the size of the screen diagonally. That's a big laptop.shining2001uk wrote:I cant believe its so complicated! I'm still none the wiser! the screen is 17.3" WLED High Definition + (1600 x 900) TFT Display with TrueLife™. so i guess thats an LED screen.
WLED is White Light-Emitting Diode. Yes, that means LED back lighting as opposed to CCFL back lighting. It just means it is thinner and uses less power. It doesn't, in any way, improve picture quality.
High Definition means it supports 720p display resolution (1280x720) and at 1600x900 actually exceeds that. No big deal as LCD monitors have supported beyond HD display capability before HD even came out. That's just advertising.
TFT is Thin-Film Transistor. Standard among modern LCD displays and doesn't even need mentioned.
TrueLife is a gimmick name for an anti-reflective screen from Dell. They don't even make their own screens.
