I think I have a dead or stuck pixel

[ToxicGhost98]

Now I don't know what causes this, and I have only had this monitor for two months, so I'm not sure if  I got a dead or stuck pixel on the top right corner of my AOC monitor, but I have used JscreenFix to get rid of it, 10 minutes later nothing changed, and if I put my cursor over the colored pixels to fix it, I can see the bad pixel over the cursor. Is this supposed to happen or what?

No, this is not supposed to happen.

RMA the monitor.

 

What color is the dead/stuck pixel? How many is it?

It looks grey/black, and it is one. Will it spread?

Almost all manufacturers will refuse RMA if its only a single stuck/dead pixel, ESPECIALLY if its in a corner.

You need to check the manual/warranty card where it should specify their stuck/dead pixel policy.

Well AOC accepts RMA for even one I read it online.

Nice.

So does anyone have an easy way on how to tell if a pixel is either dead or stuck? Also is there a way to prevent them from even showing up in the first place?

If the pixel is grey, or black, it could be dead or stuck. If it's a color, then it's stuck.

Yes, purchase a monitor that doesn't have any manufacturing defects, or try to RMA this one.

Depends on what class of monitor it is.

With class 1 it would be replaced, but with class 2+ you're right.

But part of the RMA process is getting in contact with the company who produced the product (or the store), which will of course inquire about the amount of dead/stuck pixels.

 

It's not up to me to assume how the manufacturer will handle this, especially when I don't even know what monitor we're talking about.

dead = black

stuck = anything else (blue, red, green, or a combo of these; white, purple, brown)

A dead or stuck pixel is a manufacturing defect, where one or multiple of the subpixels (because every pixel on your monitor is 3 LEDs) do not behave as they should. There is nothing you can do about it. You either have dead pixels, or you don't.

Update: Idk if it’s just me but I feel like it’s starting to slowly disappear. Can that even happen? This time I let Jscreenfix run for 30 minutes. I also tried to use my hand to kinda put a little pressure to get it out, and it kinda moved up to the top right corner even closer.

Massaging can be risky, as you can end up breaking other pixels or doing more severe damage.  If you end up leaving pressure damage then that could be a huge problem trying to get it replaced under warranty.

Yes, sometimes they will recover slowly over a long period of time by simply exercising the pixel as Jscreenfix attempts to do, but there's no guarantees it would be a permanent fix.  Then again, there are no guarantees a brand new screen wouldn't develop the same problem either, its just one of those things.

I see, thanks for the info!

That said, I never used to have pixel issues.  My current monitor and one of my laptops is the first time I've ever had dead/stuck pixels.

 

The laptop makes sense, its been knocking around in transit, but the monitor is disappointing.  It doesn't even look like stuck pixels, looks like a dirty mark but I think that's because its stuck sub-pixels on a 4K monitor, so they are so small you can't see them individually.

I don't get it what exactly causes this? I have a desktop like does this happen naturally? Because I only had it for like 2 months.

Depends on the quality of the panel, it's very common in lower end panels and there are many causes. Nothing you can do to really prevent it. A lot of cheaper monitors will have them on arrival or develop them over time, nicer high quality expensive monitors from well known manufacturers that use high quality panels don't get them as often, and almost never arrive with them unless something in transit caused them because they usually check for it in Q.A. before sending it out. AOC is one of the monitor manufacturers I would consider in the mid range of products, not a huge fan myself but they definitely aren't the worst. You have three real options with the monitor: 1. Deal with it, hope it goes away and doesn't get worse. 2. RMA it and wait a couple weeks to get a replacement, that may or may not have or develop the same issue. 3. See if you can still return it or try to sell it and get a new monitor from a different manufacturer.

You're right but I honestly don't even know if it is a dead pixel. It looks kinda white sometimes like it's not dark black all the time. I also used MSI afterburner and increased the PC power limiter slightly and the fan speed. Did that have anything to do with it?

I really don’t know if it’s dead. It doesn’t look that black. Sometimes it’s grey and it can be slightly looking transparent when I put the cursor over it. I feel like it didn’t dissapear at all. I feel like it was my imagination the whole time. But when I record it through my camera phone using a color tester, I can slightly see color over it.

They aren't always dead, they can just be faulty where it comes and goes, or a sub-pixel (one specific colour component of a pixel).

 Here’s what it looks like from up close camera. See it? It doesn’t look like a pixel up close

[ToxicGhost98]

It actually might not be a dead pixel. I think it is dust. It's inside the monitor screen so how do I clean it out?
