Oh boy, what a day!!!
So it started like this: 2 days ago my laptops’s screen started to act funny!! I got three red dots in the right upper corner.
So good so far, I searched for a quick fix and I found a free software called UdPixel (google it). Just let it run fon the stuck pixel area for 2-3 hours (or maybe more) and it will come back to life. It worked just fine for me!
