Windows 10: Hi my Asus laptop screen is dim even when I turn the brightness up it's still the same I...

Screen dimming even at 100% brightness

Hi recently bought a Lenovo laptop, a Lenovo V14-ARE laptop, and as soon as I turned it on I noticed, when I put it on 100% brightness it is bright and vivid but then it dims. After a while, the screen brightens again then proceeds to dim once again in a
few seconds. When I plug it in to charge, the screen is bright and vivid but as soon as I unplug it, it dims. I already left clicked on the power icon in the task bar, went to power options and selected "choose when to turn off the display", clicked "change
advanced power settings", scrolled down to "display" and opened its list, but the only option I have for the display's list is "turn off display after", in the Youtube videos I've seen they have an "adaptive brightness" setting or something like that and that
fixes their problem but I don't have that option. My power plan is also in high performance and everything is "on battery" but the problem still happens.

Can this problem be fixed?

 

Asus laptop automatically dims screen when I start a software/game in fullscreen

My laptop is an ASUS with two GPUs:

• (Integrated) Intel hd graphics 520. I think this manages the monitor.
  
• (Discrete) Nvidia geforce 940M. For games.
  Both have the latest drivers.
  

What happens is when I start a game, the screen dims and I am unable to increase the brightness. Some notes:

• The backlight keyboard also acts up. Turns itself on.
  
• It only occurs in fullscreen mode.
  
• I have "adaptive brightness" turned off in display settings (I have no adaptive brightness option in power options).
  
• Some people on other threads mention the "Intel Power Saving technology". I have no such setting in my Intel control panel.
  

Everything is absolutely fine outside programs. But only when I start games in fullscreen, this happens. It's quite annoying.

I think my issue is the same as this: Can't disable auto screen dimming on ASUS laptop Windows 10
However I do not see an option to turn off power saving tech in my control panel (Intel command center).

 

Laptop Screen Brightness is not the same as Secondary Monitor's brightness

After I installed windows 10, I noticed that the screen brightness on my laptop's screen was dimmer than the brightness of my secondary monitor. Not dim enough to suggest a problem with the lamp, but just dim enough to be annoying, as though it was turned
down in the settings. I went through and tried to change the screen brightness, but it failed to be effected. Is there anything I can do to fix it?
