So when i play a video on youtube on my pc, it automaticly chooses 144p and it's really anoying. In settings -> videoplayback (or whatever it is called in English) i have checked the Box that says: always choose the best possible quality for my internett conection and the size of my display i'm using. It still always choose 144p, and my internett isn't really that slow. If i choose 720p or 1080p it Works fine. I have a 24 inch display. I also tried to check the Box under that said: always play in HD in fullscreenmode (if avalible). Still nothing. Hoping you guys could help. Thanks in advance
