    Hi everyone,

    I’ve connected my Formuler Z11 Pro Max to my LG Smart TV, but I’m encountering a recurring issue. About every other time I start the device, it enters a sort of bug mode where the TV rapidly switches between HDMI ports—about once per second.

    To clarify: my Chromecast is connected to HDMI 1, and the Z11 Pro Max is connected to HDMI 2. When the issue occurs, the TV switches back and forth between HDMI 1 and HDMI 2 continuously.

    Have anyone else encountered this issue?

    Is there any difference if you swap the devices on HDMI 1 and 2?

    Can you share the exact model of Chromecast you have connected?

    Connect z11 pro to hdmi 4! It supports 4k@120hz

    3 and 4 on my lg are hdmi 2.2 and arc. And supports 4k@120hz.

    Hdmi 1 and 2 not.

    I find it out 2 years back. Hdmi 4 is my z11 pro max, hdmi 3 is my xbox and hdmi 2 is my raspberry pi.

    See added photo as example!

    Go on lg tv to settings, then search at system devices or so and then turn off hdmi cec.

    I have an older model, but will give it a try later today.
