I Found Dead Pixels on My ASUS VG259QM Laptop

I've been using the Asus VG259QM laptop in my family home and it's been working fine. But, when I moved into my student house, there was this huge dead pixel on the screen. At first, I thought it could be my fault and didn't tell anyone about it. But when I had to move to a different student residence again, I realized that this wasn't a problem caused by me. It's just a regular problem with your monitor. The pictures I sent only show a portion of it. There are about 20 dead pixels in the bottom right corner of the screen now. Look at these dead pixels in the picture. They're a bunch of 4-5 pixels combined, and it's really annoying!
