Dedicated Video Memory.

Is there any way to increase the dedicated video memory? I just think mine is really low at 128MB only.

 

Dedicated Video Memory

Hi people of the Microsoft community, I have a problem with my Dedicated Video Memory on my PC. The system says that the PC has a Total Available Graphics Memory of 4187mb, Shared System Memory of 4059mb and finally... Dedicated Video Memory of 128mb. That
is a HUGE difference from the shared and total available graphics memories! Please help find a way on how I could increase or fix the dedicated video memory on my pc. I own a Windows 10 HP Pavillion with an Intel Core i5-4210U CPU 2.40GHz with 8GB of RAM and
a 64 bit operating system.

Thank you in advance to anyone who has tried helping or answering this problem,

Jeff

 

Dedicated Video Memory

Before I proceed, I need an expert's opinion, someone who knows what they are talking about.

Is it possible to increase dedicated video memory in Windows 10.

Now before all of you hurry to answer, I have been to almost every forum and I was almost convinced that it is impossible for a laptop since the setting is no where in the laptop bios(only in the PC bios).

This is what changed my mind:

When I had windows 8.1, my dedicated video memory was 0mb and available graphics memory was about 1200mb , I was convinced by every forum online that it would never change BBBBUUUTTTT when I upgraded to windows 10, all of a sudden the dedicated video memory
became 128mb and available graphics memory became 4176mb...hence my conclusion is that it can be changed, the question is, how?...if you have no idea please don't answer.
