Last edited by Quarter on 2019/12/9 09:37 As described above, the webcam image has grey lines and occasional green flickers. This only occurs when AC power is plugged in, everything works perfectly when using battery. I have removed and re-installed drivers with no success. This is a brand new laptop that I removed from the box yesterday. I see that there are two other questions with the same issue, but no answer has been provided. Is this a hardware issue and do I need to return my laptop or is there a software fix?

Hello! I have the exact same problem. I notice gray lines everytime I do a videocall only with the AC plugged in. My laptop is an Asus Zenbook 14, model UX431F. Can I resolve it without updating the BIOS? All the drivers are correctly updated atm. Thanks!

I have the same issue on my UX431F with the built-in camera. The screen flickers with horizontal bright stripes. Very prominently when using web applications a bit less when using the camera app or Skype. Removing the power cord will reduce or completely eliminate the problem. The animated GIF from original poster perfectly illustrates the effect. When will there be a fix for this issue?

@Blake_ASUS I am having similar issues as well. I tried installing the BIOS version 304 released on May 25th for my Zenbook 14 UX431FN, but it did not work. Could you please pm me as well? Thank you!
