Blue pixels on monitor


  • Android

    Hello,

    I've been having this issue where there sometimes appear some blue pixels on my main monitor;

    For example, here's a screenshot of a picture that still shows the blue pixels:

    Here are some photo's of the blue pixels or w/e they are:

    The blue pixels only appear on my main monitor, which is a BenQ 144hz. Oh and I'm running Windows 10 Home, 64bit.
    When I disable f.lux or move the program to another monitor, the blue pixels disappear.

    I've been using 6500k for daytime, and 2700k for nighttime with slow transition speed.

    Thank you.



  • Those pixels are probably stuck. That's a lot of pixels to have stuck though. I think it's just that f.lux is making it easy to see them.

    For future reference, screenshots can't show problems with a monitor - only photos can.



  • @xDiglett Use 1200K and various other settings, like candle and halogen, and let us know if you still see them faintly. I agree with @TwoCables it's monitor related.

    How long have you had this monitor?

    If you're asking in order to determine if it can still be returned or exchanged, then I would agree. That's what I'd be doing at this point. Either that, or I'd be trying different monitor cables.

    @TwoCables Thanks for the suggestion, but I'm not sure honestly. I've tried different sites where you can test for "dead/stuck pixels", but I don't see anything. About the screenshots part, I know, just stating what I made photos of.

    Is there any reliable way to make sure it is in fact the monitor?

    Also, it doesn't just appear on one place. If I move that image, the blue pixels come along with it, only on the same part of the image.

    @Tungsten_smooth I can see them most clearly on 3300k only on the image I posted, and if I drag the image around my screen the pixels stay on the image. I've had the monitor for 6 months now.



  • Please edit posts instead of making new ones. Now I have to try to reply to both. :P

    Then obviously those are a part of the image and there's nothing wrong here.

    @TwoCables Well no, since if I drag it to my other monitor it shows no blue pixels.

    lol I know exactly what you're talking about here. It's all in your original post.

    Anyway, I'm not seeing these blue dots on my end, even if I set f.lux to 1200K. However, I have a very different monitor. Perhaps this is just the way this monitor displays things. I don't know. Maybe those pixels are always there and you can actually see them on that monitor with warmer color temperatures in f.lux. Either way, if those pixels move with the image, then those pixels are in the image and nothing is wrong with anything.

    OKAY. I FOUND THE SOURCE.

    Like I said in my original post, my monitor is capable of 144hz. I just switched it over to 60hz and guess what, no blue pixels.

    Just need to figure out how I can keep 144hz and still hide those damn pixels :p

    Might need to check my cable maybe?

    The source is the image. 144 Hz is just allowing you to see something that is always there in that image at the warmer color temperatures.

    It's funny that you did this because I was just getting ready to ask you to change to a different refresh rate. I didn't really have any good reason for it other than, it was something that could be changed.

    I guess your right. Thanks for helping!
    At least we know it's not a dead pixel ;)

    You're welcome!

    I think that dead pixels would be black. My first thought was that you had stuck pixels, but when you said that they move with the image, I knew right away that this was something in the image itself, that it has nothing to do with the cable or the monitor or f.lux.

    Maybe just don't allow f.lux to change the color temperature when you're playing games. Like, set it to 6500K.
