Greetings. This isn't the most tech related post. I have moved around my monitor quite a lot lately. I decided to move it on top of a shelf in front of my bed, as a mini theater in my room. I am using my old 20in monitor from Dell. My problem is that the shelf is a bit tall and shakes a little. I do get paranoid often and I am worried my monitor will fall on my bed or the floor. What will be the best way to secure it from moving? Any replies will be greatly appreciated.
