P15xSM HDMI external monitor won't sleep, just goes black but stays on?

So I got this P157SM and am running into random odd issues.

First the darn fans don't turn off once they max out on games, touchpad is a mess and jumpy and now I have an issue with the video out I am wanting to confirm if just me or others.

I am on bios ending in 06 and EC 05 and have the internal monitor disabled and an external monitor hooked in via HDMI set to 1080p 59/60Hz.

I have screen saver disabled but set to turn off monitor after 10 min. Came back later and noticed screen was blank but still backlit and on.
Move mouse and it came right on.

So I set to 1 min and watched, same thing.
It looks exactly like what you would get if you set the screen saver to Blank.

Anyone else with HDMI monitor having similar?

On my old P150HM had no issues.

So I fixed that. Seem in Intel Graphics you have to disable the option to bring audio over even when the screen is off, so now my screen will properly turn off but in doing so a new issue I find.

The screen does go off and stays off but my speakers make the sound as if something is being plugged in and unplugged over and over and at same time the GPU light to tell you if iGPU or dGPU is working goes on and off like it's turning nvidia card on and off while the monitor is sleeping??

Ugh, always got to be something huh... Anyway anyone got ideas on that?

So I just love talking to myself lol but anyway it's related to HDMI still, and possibly sound.

I ended up putting an HDMI to DVI converter and moving the plug on my monitor from HDMI to DVI to fix it.
Kind of annoying. I was looking at getting a DP based monitor but now have the same fear if it has audio.

I don't care for audio on monitors as I have my own speakers but mine do have built-in sound, just never use it. Unsure if the same would happen on a screen without audio but even so should be a way to handle this.
I even tried disabling the Intel Audio but when on HDMI it still happens.

Oh well, for now at least I worked around it. Hopefully someone has a solution I am missing
