Reddit users recommend using Device Manager to troubleshoot display problems – how?

Device Manager can be helpful for identifying and resolving display issues. Open Device Manager (search for 'Device Manager' in the Start menu). Expand 'Display adapters'. Right-click on your graphics card and select 'Update driver'. Choose 'Search automatically for drivers'. If that doesn't work, try 'Uninstall device' and then restart your computer to reinstall the driver.
