My unit is predator helios 300. Ive been using it for almost a month now, average of 4-5 hours daily gaming use at 20-40% brightness. Is this backlight bleed still normal? Photos taken using backlight bleed test. i have 2 pictures, one on 50% brightness and the other is 100% brightness. Thanks!

    Good afternoon epengMD   !

    This issue is known as Backlight Bleeding or Bleeding.
    Also commonly called "Cloud Visualization", Clouding, Backlight Bleed or "Mura".
    Unfortunately, this is a question currently posed by many screen producers.
    Any brand or developer is subject to this.
    There is no exchange policy of any company regarding this issue.
    Several companies present this issue on their screens like Sony, Dell, Asus, Acer among others.

    Here's Acer's bleeding information here: https://answers.acer.com/app/answers/detail/a_id/48248/~/solving-solving-solving-solution-da-luz-de- light leakage background # _ga = 2.116715535.889737960.1565913543-1593109761.1565913543

    However, I have some tips that may be helpful before moving on to the screen swap:

    Tip 1: Use the program called DPT (free) (http://www.dataproductservices.com/dpt) to analyze the effect.
    The ideal screen for clouding software is solid black or Circle.
    Be aware that the darker the environment, the greater the visual incidence of these leaks.
    During the process make sure that increasing and decreasing the screen brightness can check the exact points of occurrences.

    Tip 2: Use your equipment in a bright place where light comes from the back.
    This will enhance the contrast and deeper black tones.
    In very dark and / or semi-dark places, the probability of seeing such clouds is more likely due to the non-incidence of any other ambient light source.

    Most importantly, these leaks are not so loud that they can completely interfere with your visual experience.

    PS: Be aware that if you decide to trade, the next one may come better or worse! It's a risk!

    PS²: In this link you can see that even other brands already have their guides to address the issue: https://www.dell.com/support/article/en/brbsdt1/sln304886/solution-de-problemas- leak-light-leak-on-a-lcd-monitor-or-notebook-lcd-screen? lang = en

    Yeah, it's normal. It shouldn't be bright enough to interfere with gaming though.
