Hi everyone,
I’m having an issue with my laptop screen and would appreciate any help.
Device: Dell Inspiron 15 3511
Operating System: Windows 11 Home (64-bit)
A few days ago, I noticed that the left half of my laptop screen became completely black, while the right half continues to display normally. The laptop itself seems to be working fine, and I can still move the cursor and use applications on the visible side of the screen.
The problem appears as soon as I turn on the laptop and remains even after restarting. I haven’t dropped the laptop or caused any physical damage that I’m aware of. I also updated Windows recently, but I’m not sure if that is related.
Things I’ve tried:
- Restarting the laptop
- Updating the graphics driver
- Changing the screen resolution
- Connecting an external monitor (the external monitor works normally)
Since the external monitor displays correctly, I’m not sure if this is a screen hardware issue, a display cable problem, or something else.
Has anyone experienced a similar issue where half of the laptop screen goes black? What could be causing it, and what troubleshooting steps would you recommend before I consider replacing the screen?
Thanks in advance for any suggestions
My computer screen became half black, with one side displaying normally and the other side completely dark. I first checked whether the issue was caused by a loose or damaged display cable by reconnecting it and trying a different cable. I also restarted my computer and updated my graphics drivers.
To determine whether the problem was with the monitor or the computer, I connected the monitor to another device and tested a different monitor on my computer. If the black area still appeared on the same monitor, it indicated that the monitor itself was likely faulty.
In my case, the issue was usually caused by a damaged LCD panel, a failing display driver board, or a loose internal ribbon cable inside the monitor. These hardware problems generally cannot be fixed through software settings. If the monitor is under warranty, contacting the manufacturer for repair or replacement is the best option. Otherwise, a repair technician can inspect the internal components, but replacing the monitor is often more cost-effective than repairing a damaged panel.
