    Hello everybody,

    For roughly 1 month I'm trying to get a decent 21:9 29" IPS monitor.
    I bought and returned 5 of them (4 x LG 29EA93 and 1 x ASUS PB298Q).

    On 4 of the 6 monitors I had some kind of 'dark light bleeding' precisely on the bottom right corner.

    Here is a picture of the 6st screen who still has the problem :

    I'd like to know if this is something common with this kind of screen and I should just be happy with it, or is it some kind of defect ?

    Thanks :)

    This is called: non-uniform back light.
    All consumer grade monitors are non-uniform.

    It is costly and makes the monitor heavier and thicker to make a uniform back light display, which is why only professional grade monitor have this feature. (it increases shipping cost, and for some reason, despite the stand taking the same space on your desk, thinner design is a marketing point that sells).

    You will notice the same effect on all your tablets, laptops, and any LCD TV

    Thanks for your answer.

    I know that there could be some darker spots with edge led backlit screens, but this one is bigger, and only in the bottom right corner.

    I wonder if this is a defective LED or something ?

    normally "edge lighting" is only at the bottom for LCD monitors, and top and bottom for most LCD TV's due to their size.


    It could be 1 or 2 LEDs that is faulty. I would look into that with others with the same monitor. If you can return it, do so, but if your next one has the same issue, then this is the monitor that is made like that.

    On the 6 monitor I got, 4 of them had that thing. The other 2 were worse (big backlight bleed, dead pixels, and so on).
    But the other 2 didnt have that thing in the corner.
    Could it be a défective batch of screen ?

    I think if you have gone through 6 monitors you are expecting too much uniformity for consumer grade screens.

    I would agree. It could be a revision thing.. where some revision has the issue others don't
