i have a benq xl2411 and there is a purple pixel stuck i think but i am not sure about that and wanted to get help from you guys. It is purple on black and blue screen and invisible at white red and yellow. Thanks in advance to respondents.
 
Typically dead pixel is black, so no light at all, that is more like a stuck pixel.
If it has warranty, take it there.
1. Turn it off for 24h.
2. Play on youtube for stuck pixel (usually video is one hour showing collors) and care it might cause seizure also video has to be in full screen mode.
3. Probably taking to repair shop.

For other fixes? Im not quite sure, try resseting settings in monitor menu.
 
I'm relieved that it is a stuck pixel. Also i fixed it a while ago and it repeated now. Should i try to fix it or go for the warranty and want a new one? (not sure they will get it for that one pixel)
