    Hello together,

    my display had to been changed and the technician came with an LG Philips LGD049B display which is not that kind of anti-glare I was used with my broken AU Optronics B156HW01 V1.

    Ist there a chance to get a anti-glare display for my E5570 with proper anti-glare coating?

    This LG Philips display has very poor anti-glare coating especially when looking from the side to the laptop screen.

    How is your experience with the LG Philips LGD049B

    I had a similar experience with the E5450 and the E7450, with the exact same respective screen brands as well. I bought it off ebay. You could try complaining to Dell. Here's a reference side by side comparison: http://forum.notebookreview.com/threads/lg-vs-auo-14-1920x1080-anti-glare.792895/

    Thank you for the link. You can really see the difference between the two coatings.

    Anyone have information about the pulse-width modulation of the LG Philips LGD049B

    I have found some articles in the internet saying, that it hase PWM below 95% brigthness. I just want to avoid that this is going to bother me later when working long on the laptop screen.

    This notebookcheck review of the Precision 3510 with the LGD049B did not detect any PWM. However, the review wasn't very complimentary about the overall display quality. I wonder if the use of PWM for display dimming is, at least in part, a design decision by notebook manufacturers.

    I guess I should complain at DELL...

    However, if Dell will change the display again, could I get a display worse than the LG Philips I have?

    It seems that there is no AUO display around and would be a Samsung display worse or any other manufacturer?

    It's a technical decision that's all over the electronics world, because it's more power-efficient than linear regulation.

    The frequency at which said PWM dimming is done, that's a whole other story...

    So having used both those screens side by side, I noticed that the LGD PWM wasn't detected in any reviews, but I felt like it had it. It never felt like it was too bad though, like some other machines, so the frequency might be higher. Now, that was on the 14 inch versions but it's possible the behavior carries over to your specific model.

    IIRC, Notebookcheck recently updated their PWM test equipment which has unraveled PWM frequencies (albeit really high) on machines that the old test equipment couldn't detect. (Someone correct me if I'm wrong).

    The AUO screen is golden.

    The easiest thing for you to do would be to look for a cheap screen on ebay and swap it out. If you're not up to it, just complain to Dell. Unfortunately, 'antiglare' coating level is not something they spec on, it would seem.

    End of last week another DELL technician came with another display. Unfortunately he came with the same display so I told him not to change the display as it was as glossy as the one I have already replaced :(

    He said they have only the to manufacturers of displays LG Philips and BOE in stock.

    Do you have any experience with BOE displays?

    The LG display I have does not look like a real anti-glare display as you can see that there is a slide (perhaps for the anti-glare effect) stick with tape around the edges on the display which the AUO I had originally does not had.

    And now? Any recommendations?

    No experience with BOE displays, but I'd just buy it off ebay. It's annoying, but the AUO antiglare is so much better that it was worth the price to me.
