CrossOver 27Q LED/LED-P, 27M LED, & 2720MDP GOLD LED Monitor Club - Page 578

Yeah that looks like a dead pixel (more than one actually, it looks like a group) but I can't tell because I'm not sure how zoomed in the picture is.

Some pixels get stuck in a certain colour, this is why they don't show up in certain spectrums. That looks to be a red pixel(s) that is stuck.

How noticeable is it during normal use and also during gaming?

I have a single dead pixel (black) in the upper left quadrant of my display but even on a white background it is very, very hard to detect unless you intentionally look for it. Depending on how noticeable it is, depends on what you should do. It's a pain to send it back though.

Glad to hear it. thumb.gif

I guess it depends when their couriers come to collect the monitors. I ordered mine on a Thursday night, it didn't get physically shipped until the next Tuesday, it was here for the Thursday. It took exactly one week to arrive (including non-working days) from S. Korea, so it wasn't a complaint on my behalf, I was extremely happy with the delivery time. I'd have been even happier if it had come quicker but maybe it's due to me ordering at the back end of the week.

Everything looks good except there is just one dead/struck(not sure) pixel on the left side corner location. I posted the image so if someone could tell if its a dead/struck pixel it will be helpful.

This pixel shows up only on white/green background.. It is not visible on black/red backgrounds(not sure if this is relevant)

Looks like a dead green subpixel.

You mean power supply. They will supply a 120Vac in, 24Vdc out external power supply. They will give you a f/m plug adapter, but I just used a standard ac power supply cord same as what your computer uses to receive 120Vac.

Looks more like a hot/stuck pixel than a dead pixel.

Dead pixels appear completely black.

Is there a way to get rid of this struck pixel?? I tried some software that changes the colors rapidly. I am afraid how long I can force the pixel with the software without resulting in any kind of damage??I tried like 5min and shut it off.

I agree. I doesn't appear in blank screen also(only backlight). I can only see it on red/white backgrounds.

Try looking up pixel massaging techniques.

Other than that, I have no idea.

Hot/stuck pixels usually go away with time.

Stuck pixels are also known as stuck subpixels - a stuck green subpixel will appear green on a black background.
Hot pixels are pixels where all three subpixels are lit - they are white in all instances.
Dead pixels appear dark. You can have dead subpixels - they will be dark.

For IPS screens, cycling that pixel through turning green on and off in that part of the screen might help. It shouldn't damage your screen and can't hurt.

I don't get this! The LED Driver in my 27QLED went out. So I replaced it along with the power brick since the power brick was out putting 29v instead of 24v. The NEW power-brick has short circuit protection and it is still kicking off. Do I really need to replace the damn input board now?

*sigh*
