Question confused about "Dedicated Video Memory"

Sep 22, 2019
i had a laptop with Pentium P6100 2 GHz, 6GB Ram, and 1760MB HD Graphics (Pentium),
so i was a bit curious and confused about the Dedicated Video Memory which it was 128mb by default. i watched some youtube vid about how to increase it. i dont know whether it worked for me or not because if i look at my BIOS, it's still written 128mb. but when i look through Right Click > Screen Resolution, it's 192mb. which one is right? the BIOS, or the Screen Resolution window?

*sorry for the bad english btw ;-;
