Question A green pixel is blinking like a star on my monitor...

[blueskyx5]

I just got a new monitor and for a few days now I've noticed tiny green 1 pixel flashing on top of black images. Since it moves, I guess we can't call it a dead pixel. I passed the dead pixel test, there are no dead pixels. When I touch this thing that looks like a distant star, it disappears... What's going on? What is this? I don't come across it very often, I see it rarely, but this is the first time in my life that I've seen something like this and I want to know why. (Monitor connection DP)

Might want to upload a video clip of what you're experiencing onto Imgur or their ilk and then pass on a link for us to see.

Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

I think I found the answer to this question. This is probably a stuck pixel. And I understand that monitor manufacturers have taken some precautions against these possibilities. Dell for example, calls it “LCD Conditioning”. And similar to the dead pixel test, it works until it is stopped by the user. That's what I understand from this technical service ticket https://www.dell.com/community/en/c...-doesnt-seem-to-work/647f4f11f4ccf8a8de7d5510 I saw the same application on LG monitor (I am not the author of this topic) https://www.reddit.com/r/computers/comments/1dtusld/why_does_my_display_do_this/

I ran it for a while, and now I think it's gone. But why are we still dealing with these things, hasn't technology developed? These problems should have been completely eliminated from our lives by now.

I've been following this problem for a few days now. Not all monitors may be the same, there may be more than one scenario... I noticed that this pixel jamming only occurs when I touch the screen. If I touch the screen a little with my hand or move it over it, a green or red pixel flashes somewhere on the monitor... Then, when I gently press it with my hand as if I were cleaning it, it disappears.

If I don't touch the screen with my hand, this pixel jamming doesn't occur. But I think the weird thing is why don't they just encase these monitors in a hard material like glass? All monitors, whether TN/VA or IPS, are manipulated to some extent when touched. This can actually be avoided, it may just increase the cost a little. I think the old TN monitors had a more durable outer casing. Yes, Regardless of TN / VA / IPS, the newly produced monitors have better image quality, but they are more sensitive to external manipulations.

I'm not talking about a brand that has no quality standards or a technology from 500 years ago. I'm talking about Dell's TN monitor produced in 2022. I wish monitors were rock solid.

This problem seems to have gone away for about 10 days now... I had run an app called LCD Conditioning for 8 and 10 hours a day for a few days. (An application that is similar to the constant flashing of colors in the dead pixel test...) When I last saw it, I pressed and touched the screen tightly... (Not too much, but I pressed it as if I were pressing with an eraser on a piece of paper... I think they were scared and decided not to come again)

Interestingly, I have not seen any pixels stuck on the black background on the monitor for 10 days. This result may indicate that, on some monitors, sometimes due to chance, stuck pixels may not appear again. Actually, 10 days is not enough to make this opinion, but I was seeing it every day before.... I am making this update so that if someone from Google reaches out, they can at least get an idea from the user experience.
