HDMI input switch, HDMI does not work

hi,

I have All in One PC HP Envy 23" K2A79EA.

I connect my raspberry pi via HDMI with brand new HDMI cable to HDMI input port in my Envy 23" AIO display. 

I press HDMI input button and nothing happens.

I press and hold HDMI button and nothing happens.

I have reinstalled noth Intel graphic driver and NVIDIA graphic driver but still I can not get neither HDMI input nor any additional menu when HDMI input button pressed.

Furthermore I can run HP PIP software due to no compatibility issues.

Any ideas ? Any help ? Is HDMI input port dead or not working at all ?
