"Macbook Pro M3 Pro screen blurry/black screen: Hello everyone. I want to ask an about the problem in my macbook. Context: Macbook pro series laptop M3 pro chip, the laptop has been used for about 1.5 years. Yesterday I used it to watch youtube and suddenly the screen was blank/burry but the laptop was still on. I have applied the tutorial method on the internet, but it still doesn't work. I attached a picture to give more interpretability about the problem. I also have connected it to the hdmi external monitor, and all I had was the mac background."

Distorted Window:

It might the be window or the entire app that is distorted, rather than the entire Mac. So, see if either the following works...

A. Create a New Desktop:

Hold the fingers down on the trackpad. Then, swipe up. Click the "X" on each window as they appear from the left. Use the new desktop that remains., making a new one, if necessary on the face-gjer edge of the Desktop list.

B. Force Quit Web Browser Apps:

Simultaneously hold down: [option + command + esc]

One at a time, select the app, and then click Force Quit Button on bottom-right corner of screen. Start with all Web Browsers, as they may be playing this YouTube video.
