    I’m running on a Lenovo computer Windows 11 and my computer has white horizontal lines across the bottom of the screen, and vertical blue and red lines all the way down. I’ve tried lowering the refresh rate to 60 Hz from 165 Hz, but that only lowered the opacity of the lines. My display resolution is set to the recommended 2560 x 1440 as well as my scale 150%.I have not damaged my screen in any way, so it’s not an issue with that. The only thing I was doing when this happened was browsing the web, so I have no clue what happened. I ran a quick scan for viruses using Windows Defender just

    Lenovo 14s display - unreadable with horizontal and vertical lines.

    Today my Lenovo 14s screen is now showing all horizontal and vertical lines, and is absolutely unreadable. Even the red Lenovo boot screen is all horizontal lines, and unreadable. Suggestions. By the way, the warranty expired on October 31, 2023, like just ten days ago. *Banghead Not that it really matters, but Win 10 64 2H22.

    Vertical and Horizontal Lines

    I was away this morning and my Windows 10 computer performed a major upgrade. The result is that I now have two gray horizontal lines and two vertical gray lines on my screen. They form nine rectangles that overlay every program. I checked screen settings,
    etc and nothing works. My system, computer and monitor, is from ASUS and worked fine until the "update."

    Vertical and Horizontal Lines

    The problem I had with vertical and horizontal lines has nothing to do with Windows. I have an ASUS monitor. There are small buttons along the bottom of the screen case. It is easy to inadvertently touch the buttons. One of them turns on an "alignment
    grid." Simply push the button to turn it off.
