Hello @ItzLindo 

- Use another display cable

- Check sockets (both computer and monitor) for dust/dirt

Press the [ Windows key] + p to cycle through one of four display states:

● PC screen only: View the screen image on the computer only.

● Duplicate: View the screen image simultaneously on both the computer and the external device.

● Extend: View the screen image extended across both the computer and the external device.

● Second screen only: View the screen image on the external device only.

Each time you press the Windows key + p, the display state NOTE: For best results, especially if you choose the Extend option, increase the screen resolution of the external device, as follows. Select the Start button, select Settings, and then select System. Under Display, select the appropriate resolution, and then select Keep changes.
