Monitor problem HP 27xq

I have these light streaks that appear in some areas and disappear in the midst of the colors

I never erased the screen and I don't know what to do

And the problem frustrates me in some games when it appears

I want to point out that what I noticed is that these relics were in the form of menu icons for a game I played a lot ( Although it is not very clear, I made sure that it takes the same place and shape as the icons in this game ).

(It is noticeable that this defect does not appear in the five colors R-G-B & Black & Withe = with app UDPixel)

Hi @kinglords

Can you try another monitor to prove whether the problem is in the display or perhaps the computer, GPU for example?

Does it only appear in games?

First, thank you for the reply.

- I used another computer with this display and same problem

- I changed the cable from Displayport to HDMI since I relied on Displayport a lot (same problem with HDMI ).

Does it only appear in games?

The problem appears all the time, but it is noticeable that the longer i use the screen, the more lines appear, which are basically, as I said, words and icons of the things that I use for a long time.

@kinglords

It's almost like screen burn in but you'd think that it would be noticeable when testing solid colours as well.

Maybe try a different resolution (frequency refresh rate <144Hz) and check.

If the monitor is no longer covered by the warranty you may have to open it up and check for anything obvious on the control board, although I think that it's more likely to be the LED pixel drivers in the panel, which are internal to the panel

Here's the service manual that may help.

I changed the screen resolution without any difference

I changed the frame refresh rate without any difference (144Hz - 120Hz - 75Hz - 60Hz)

In the solid color test, the problem is almost not seen, it is there, but you must check to notice it

As for the warranty, it ended. I even tried to open it and only opened the first cover. The truth is that when I completed the rest of the stages, but until here, there was nothing that aroused suspicion.

I think that the problem is in the panel as it is always in the same location on the screen.

@jayeff yeah I think that (panel )
