Is this a dead or stuck pixel?

[Yoiji]

I just got a replacement gaming monitor today because the other one had 4 dead pixels near the center of my screen. This one is almost perfect except for the fact that it has 1 stuck or dead pixel in the very middle of the screen. I came to the pros on here to help me understand if this is stuck(fixable), or dead(permanently gone). On a red background, the pixel is black. On a white background, the pixel becomes a baby blue. On a black, green, and blue background, it blends in completely. So is this dead or stuck?

I'm not sure. Have you tried some software solutions? I think some websites exist that claim they can help fix dead or stuck pixels. Usually by flashing the screen with a bunch of colors to wake the pixel up.

Good luck.

Sounds like the red subpixel is dead / stuck black. You could try 'massaging' the pixel to break a short or restore a broken contact which may be causing it. Most of the time though, a dead/stuck pixel either stays dead/stuck or if you manage to revive it by whatever means, it'll go dead again a short while later and won't necessarily come back with further 'treatment'.

If you don't want to deal with LCDs that have stuck or dead pixels, buy a monitor that comes with a perfect panel guarantee. Cheap monitors are usually built around surplus and reject panels with loose quality guarantees. For some vendors, you need 3-4 stuck-on or flickery pixels clumped together near the center of the screen to qualify for warranty replacement. If they're scattered, the requirement can increase to 10+.

Thanks for this reply. This monitor is a 450 dollar gaming monitor so I would expect it to have a perfect panel anyway. Do you have any good monitor suggestions that are 144-240hz with gsync that are around 200-400 dollars with this, "perfect panel guarantee?"

You aren't going to find affordable gsync monitors simply because the proprietary gsync scaler module that goes into them adds as much as $200 to the price and this increases to ~$500 for the first generation of gsync HDR modules. Basically, this means your $450 monitor really is a ~$250 monitor with a ~$200 module crammed into it. Not as much budget for premium parts as the retail price tag implies.

I'd simply skip the gsync tax and go plain 120+Hz refresh. As for what gaming monitor brands have perfect panel guarantees, I have no idea. I use my PC mostly for non-gaming and the last two monitors I have purchased are Dell UltraSharp. Speaking of which, the older of the two developed an entire column of stuck-on pixels at some point that I didn't notice until long after the warranty expired since I use that monitor mainly to read/write documents and the defect column happened to land in the margins which are always white anyway. Just shows how even paying a $100+ premium for a premium panel still is no guarantee of no latent defect.
