1 of my 2 monitors broke so i got a new one. When i plugged the new one in the old one started not turning on right away. Usually it turned on after replugging it a few times or spamming the auto select button on it. With time it becomes harder and harder to turn it on. The cables are not faulty and when it finally turns on it stays on until the next use. The problem started when i got the new monitor.
