KYY support FAQ

Common questions about manuals, registration, and support for this brand.

  • Why is my KYY portable monitor showing 'No Signal' or flickering?

    This issue is often caused by insufficient power supply. Ensure the monitor is connected to a power source (5V/2.4A or higher) using the provided adapter or USB-C cable before connecting the video signal cable.

  • Does the KYY portable monitor work with iPhones?

    Yes, but connection requires a Lightning to HDMI adapter (typically not included). You must also power the monitor independently with an external power source.

  • My monitor does not save brightness settings after turning off. Why?

    If the monitor is powered only by the data device (like a laptop), it may not retain settings to save power. To save settings, ensure the monitor is connected to an external power supply via the power dedicated USB-C port.

  • How do I contact KYY support for warranty issues?

    You can reach the KYY support team via email at support@kyytech.com or support1@kyytech.com. They offer a 12-month warranty on their products.

  • Can the KYY monitor charge my phone?

    Yes, if the monitor is connected to an external power adapter (5V/2.4A or above), it can pass power through to charge a connected USB-C smartphone.
