Video Memory Allocation

Video memory is allocated from the total available system memory for the efficient balancing of 2-D/3-D graphics performance and overall system performance. Dynamic allocation of system memory to video memory is as follows:

•256 MB total RAM results in 32 MB video RAM

•512 MB total RAM results in 64 MB video RAM

•1 GB total RAM results in 128 MB video RAM

•2 GB total RAM results in 224 MB video RAM

Analog Display (VGA) Support
