    FAQs

    Q: How do I set up my Insignia NS-20EM50A13 monitor for the first time?

    Carefully unpack the monitor, fasten the stand base, then connect the HDMI or VGA video cable and power wire to your computer or other device. Activate the connected device and the monitor. Your input should appear on the screen automatically.

    Q: What video connections does this monitor support?

    The NS-20EM50A13 is compatible with desktop computers, laptops, and several gaming consoles because it has both HDMI and VGA inputs. For optimal image quality, use HDMI.

    Use the on-screen display (OSD) menu or press the Input or Source button on the monitor. Depending on the device you’re connecting to, you can alternate between HDMI and VGA.

    Q: Can I adjust brightness, contrast, and color settings?

    Indeed. To change brightness, contrast, colour temperature, and sharpness to your liking, press the Menu button on the display to bring up the OSD menu.

    Q: Does this monitor have built-in speakers?
