dedicated graphics memory

[HSsem]

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 BUT when I upgraded to windows 10, all of a sudden the dedicated video memory became 128mb and available graphics memory is 4176mb...hence my conclusion is that it can be changed, the question is, how?

Note that the Intel® graphics controllers uses shared memory that is taken from the RAM memory installed on your computer.

The feature that sets the amount of memory that is used for video is called Intel® Dynamic Video Memory Technology and this will make the graphics controller only to use the amount of RAM memory that it requires to run the different applications or software's.

I am afraid to say that there is no way to preset this to an specific value; however, you can limit the maximum memory that it can take only. You will see this option usually in BIOS and you will have 3 options, 128MB, 256MB and maximum DVMT. Other values can be found as 512MB, etc but this depends on the motherboard manufacturer and the amount of RAM memory installed on your computer.
