The LP173WF3-which used in the elitebook 87x0w 16:9 models and Zbook 17 is the best. no grain effect (AG coating is not so strong, very comfortable), no annoying light bleeding, no color shift, no ghost. the PERFECT panel can used for laptop display indeed. It is shame that LG display is making blurry, eye-blowing craps instead this nowadays. also PWM pulsation is not seen in my 8760w.
I'm a bit surprised not to see the Surface Pro 3 listed here (hell yes, it's a laptop). I'm no fanboy, but I was blown away by the job Microsoft did on this thing - it's truly one of the best displays I've ever seen anywhere - and it's considerably cheaper than most of the competitors you list here, too. It also gets bonus points in my book for its modern and useful 3:2 aspect ratio that doesn't force you to work through the 16:9 HD "mailslot". (Only two of the laptops here are even 16:10, which is still pretty lame.)
As for PWM, I agree stats would be good. PWM is a deal-killer for me - like LED taillights (yuck!), PWM for backlights is horrid and incredibly visually stressing. I'm really not sure it's possible to crank the frequency up enough to keep it from sucking, since the blinking is the fundamental problem, and a great many people are obviously sensitive to it at frequencies that are "supposed to be" way beyond perceptible.
jza, yes. I can't stand PWM monitors at all, horrible headache starts after 5 minutes. They should check it from now. Checking PWM and PWM's frequency takes maximum 30 sec. I just cant understand why they dont pay attention for it.
Very interesting that U904 ranks so poorly, even though when you compare it to all the immediate neighbours in the table, it seems to win easily in most parameters.
FWIW, as an answer to Jeff Belin's first comment, Samsung Ativ Book 9 Plus screen is not Sharp IGZO, afaik. Sharp's panels have no trouble rendering great colours (look up the yellow issues with Samsung's panels), and are brighter while still keeping a great contrast ratio.
There are 2 missed aspects: PWM pulsation, and crystalline effect. They have great impact on the user experience, and they can be more important then ppi or color reproduction, especially in the case of long-time working. Unfortunately, there are very few or no info about them in most web reviews.
No compromises. Is the display is the most important part of an notebook for you and does it play a leading role in your purchase decision? Our overview of the best displays in current notebooks reviewed by Notebookcheck might be helpful for you. Top displays as of July 2014.
