Update = After completing troubleshooting, a DELL-Cares agent setup a part replacement.
I have my Alienware for a month now, and this started happening maybe 2 weeks ago. Sometimes, when I browse stuff in windows File Explorer, or do something in a web browser, weird flashing horizontal bars start appearing on the LCD (please see video recorded with my phone) VIDEO: [URL] (please forward to the second half of the video for sharper image) Note: 1) I already installed video drivers from Dell's website 2) It does not matter if Advanced Optimus is turned on or off 3) It only happens on the internal LCD. When connected via HDMI to a 4K TV, the bars flash on the laptop's LCD, but not on the TV 4) This problem is present on both 165 and 60hz display modes 5) Oddly, I have not noticed it while playing games 6) This is not a permament issue, it happens, then goes away for a while, and happens again. Any ideas?
