I have a Toshiba Laptop Satellite L505D-LS5001. It has a Radeon Mobility HD4100Graphic card with shared memory with a Maximum of 512mega. But it only uses 256 megabytes. I have 4gb of ram and I would like to increase my video to the maximum.

Please don't mention BIOS because I don't see a setting in BIOS that allows me to change and I know there is a possible way for me to change it.

That video card appears to have 512MB of dedicated discrete memory. It can use shared memory so some of the system memory (4GB) should be available. Windows may reserve most of the 4GB though. How did you discover that only 256MB of video memory as being used?

I determined this from two different ways. First I looked at my system properties from Right clicking on properties from my computer. I have 4gb ram installed and it says I only have 3.75 usable. Thats one way I know it is only using 256mb. Second I have Advaned system care ultimate and I looked at my system information and it says "Video Memory: 256 megabytes"

OK 3.75 GB usable means you're running a 32 Bit OS. Windows reserves some memory so you'll never be able to use all 4 GB unless you run a 64 Bit OS and that info won't help you determine how much video ram is being used. I am not familiar with Advanced system care ultimate but a simple Google search for "How much video ram am I using" returned this. The also make CPUz. Very useful tools.
