The easiest way to confirm if your monitor supports HDR is to check the manual or product page. You can also look in your monitor's settings to see if there's a menu dedicated to HDR. For both options, you might simply see keywords such as HDR, VESA DisplayHDR, Dolby Vision, or HDR10. Of course, a practical way to see if your monitor supports HDR is to play an HDR movie. Some streaming services like Netflix offer HDR content.
