  • What happens if you scroll the pixelated content (or move the window it’s in)? What about moving another window on top? Have you tried 3D software yet? Perhaps try viewing this WebGL sample in various browsers.

I have an issue with my laptop but I don't know if it is software issue or hardware. The issue is that sometimes the images shows pixelated sometimes it is ok

First:

Use the Dell Driver Update App and update all Drivers including BIOS (UEFI), Chipset, and Video for certain and all other drivers.

After the restart that occurs, update Windows fully . Check in Optional Windows Updates and do those as well.

Second:

If you still have issues, Use the Dell Hardware Diagnostics App and test all hardware.

If there is a hardware issue, you may need to have the machine serviced.

  • Dell may also have a separate driver update app - try that. Also look on their support site for BIOS, Chipset and Video driver updates and do them manually.
