I recently purchased a 55 inch Neo OLED 4K Smart TV. In General Settings>Start Screen Options, "Start with Smart Hub Home" is turned on and other options are off. I have a Firestick 4K plugged into one of the HDMI ports for viewing and recording over-the-air broadcast TV with other options being streaming with the Spectrum app and Prime Video. Whenever I turn on the TV, the Firestick displays instead of the Samsung Smart Hub Home. In fact, none of options in Smart Screen Options seem to have any affect on anything. How can I control what is displayed when the TV is turned on?

The Firestick has a setting called Equipment Control that has the options off, manual, and automatic. It was set to automatic, and I changed it to off, which resulted in a blank screen when I turned on the TV requiring pressing the home button to display the Samsung Hub. I changed the Equipment Control to manual, and the Samsung Hub now appears when turning on the TV. The recent window in the hub at least sometimes shows the last app used upon startup instead of the Firestick. Returning from the settings menu to the Hub results in Firestick as the most recent app even though it was not. In any case, I am now getting the Hub displayed instead of Prime Video thru the Firestick, which is good.
Thanks for informing me about CEC and the ability to block it. I was ignorant about it. Would an adapter be beneficial in my current situation?
Some are knockoffs and aren't made correctly. Make sure the one you get does not have a pin 13. In the pin 13 port there shouldn't be anything in it, just an empty hole. Pin 13 is what sends the cec signal to your other devices.
