    Hello,

    I contacted someone at laptopscreen.com and they showed me :

    https://www.laptopscreen.com/English/screen-part-number/B156HAN01.2/?hash=372669

    http://www.panelook.com/B156HAN01.2_AUO_15.6_LCM_overview_19049.html

    The guy said it's compatible with Inspiron 7559 and it get 72% color accuracy compared to the 45% we have right now. The only thing I don't like about the links he send me is that the contrast ratio is 700:1 instead of 800:1 and the color number is dropping from 8 bit (16.7 M) to 6 bit (262k) even if it is more accurate (something I don't understand).

    Is it a good screen?

    Someone tried with another good matte screen? Which one do you recommend that work with Inspiron 7559?

    Thank you

    EDIT : I found this one http://www.panelook.com/modeldetail.php?id=24666 from another discussion. Is it compatible? The only thing is that's not antiglare (what is hard coating 2H?). Any idea which one I should get for my laptop?

    Not worth it. What you are looking at currently is NTSC - that is not nearly as important as sRGB and Adobe RGB for most users. Your laptop's default IPS screen covers 90% of sRGB and 58% of Adobe RGB (Source: NoteBookCheck). Upgrading the panel would actually be somewhat of a side-grade the most part and you are likely to lose certain features like brightness control.

    My opinion? Waste of money.

    Ok, but mine is not really 90% sRGB. Green looks look yellowish. Also the review is with the 4K screen or the LG one, but personally, I have the 1080p BOE NV156FHM-N41 and looking for something better. I'm making photo editing and can't get it right since all colors are weird.

    Ah, my mistake. Yes, the 1080p panel offers about 60% sRGB coverage. Though if you want good colours for photo editing, you want something with high Adobe RGB rating. sRGB and NTSC are useless for that. Look for something with at LEAST 70% Adobe RGB coverage and you'd also need calibration hardware like Spyder Pro.

    Told you already - stop looking at NTSC - that is meaningless for the most part. Look at Adobe RGB for professional use and sRGB for consumer use.

    Ok, but I read that 72 NTSC is around 99% sRGB.

    But about the screen above, do you think it could work even if it has some differences from my current screen like :

    Display Mode (new screen)
    PLS, Normally Black, Transmissive


    Work Mode (current screen)
    ADS, Normally Black, Transmissive

    Lamp Type
    WLED , 15K hours , Embedded (LED Driver)

    Backlight
    6S6P WLED , 15K hours , Embedded (LED Driver)

    Other than that it all look the same.

    Also, can I get the answer about what Glare (Haze 0%), Hard coating (2H) means? Is Hard Coating a fake antiglare or it will be a full glare screen?

    How many times must I say this? NTSC and sRGB are TWO DIFFERENT STANDARDS THAT HAVE NOTHING IN COMMON

    NTSC is used in analog television and is largely outdated

    NTSC has NOTHING to do with sRGB, which is the current standard for internet, movies and other general consumer applications and it has been this way for about 20 years now. So unless you are reading fake news from the 80s, then NTSC is meaningless.

    I know that... But there is no statistic on that on the web. I don't know why... But people only seem to say that's around 99-100% sRGB and it's a good screen.

    NTSC is an old standard, hence why reviewers tend to ignore it. sRGB is what you want if you want a multi-media machine and Adobe RGB if you want to create stuff via the Adobe suite or similar software.

    In addition, you need a screen calibrator like Spyder Pro so as to actually achieve proper colour tone and temperature. Out of the box, a screen can have 100% sRGB and Adobe RGB yet still have bloody terrible colours if it is not calibrated properly. Not mention, for colour work, you absolutely NEED a Delta E value under 3.5. Otherwise, the screen is not going to be good for professional applications.
