      Provide a detailed description of the issue

      I experience screen tearing when watching content that has a lower refresh rate than 60 frames per second. It happens when I watch Youtube videos or just watching content on my own computer. There is no issue in games even if the game does not output 60 frames per second.

      Please place an X to the right of the option showing how often you see this issue using specific steps. (Ex: 'Every few times a game is started it flickers.' <- This would be "Often")

      Always (100%): X

      Often (51-99%):

      Sporadic (20-50%):

      Very Sporadic (<20%):

      Dear All,


      I have been using my Razer Blade Stealth 2016 for quite a while now and I had no problems for over a year. But now I bought an external display (Acer H277HU) which I connect through an HDMI cable with my laptop. I noticed that whenever I watch content with less than 60 frames per second the external display has massive screen tearing. When the content is at least 60 frames per second then I have no problem. The content can be either online (youtube) or on my own computer. I do not have any issue with it when playing games. Now I already researched the problem and everywhere I found that this issue can be solved with vertical sync, but I tried every possible setting in the graphics control panel and nothing helped. I am aware that I do not have the latest driver version at the moment but that is because I tried to install older versions to test but nothing worked. I also installed the acer monitor's driver but that also did not help. I also ran the Intel processor diagnostics program but it did not find any problem.
