Secondary Display through HDMI port uses only NVIDIA graphics.

I use Ubuntu 20.04 as my daily driver and I sometimes connect to secondary monitor for multitasking on simple works (not gaming). So what I noticed is when I am on NVIDIA only(Performance mode) it detects the monitor and connects successfully. But when I am in Intel mode(Power Saver) it fails to recognize/connect to the monitor. Is it normal? Does HDMI output only occur with NVIDIA GPU and not Intel GPU? I am not a heavy gamer so I want a longer battery life with Intel graphics rather than using NVIDIA for simple tasks.

    What is the notebook model? Example an515-51-75kz. In most notebooks that have a dedicated video card, the nvidia video card controls the hdmi port. Therefore, when you connect an external monitor to the hdmi port, the nvidia video card must be activated.
