how resolution size affect memory?

[nolimit]

Hi,

I want to know how display resolution affects memory performance?

is there any calculation to working out what size of memory will work at which resolution etc.

e.g If I wanted to use 1280 x 1024 = 1.3 million pixel display resolution, what is the baseline MB of memory do I need.

I have seen a simple calculation but can't remember where.


thanks in advance.

System Memory such as 1GB/2GB/4GB

I'm trying to work out, if I'm viewing e.g 8mp image on 1.9mp screen (1680 x 1050), what is the minimum ram I need to view the image.

I need the formula.

Thanks for the detailed information Darg. Now I understand the formula now.
