To adjust the screen resolution, go to your computer's display settings. For Windows, right-click on the desktop, select 'Display settings', and choose the desired resolution under 'Display resolution'.

If the monitor still doesn’t turn on, try using a different power cable or adapter. If the issue persists, contact Samsung support for further assistance.

Flickering can be caused by an unstable connection or incorrect refresh rate settings. Ensure all cables are securely connected. Verify that the refresh rate is set correctly by going to your computer’s display settings. Set it to 60Hz, which is the recommended refresh rate for this monitor. If flickering persists, try using a different cable or port.
