According to the Intel FAQ, the Intel HD Graphics 4400 can have up to 2048 MB of graphics memory.

Your image shows indeed :

Total Available Graphics Memory: 2624 MB
Dedicated Video Memory: 576 MB
System Video Memory: 0 MB
Shared System Memory: 2048 MB

Shared GPU memory is a type of virtual memory (not physically allocated) that's typically used when your GPU runs out of dedicated video memory. In most cases the shared GPU memory will not be used at all.

You're probably looking into increasing the Dedicated Video Memory (rather than the Shared System Memory), but that's only possible in the BIOS. This option might be found in the BIOS section "Advanced features" and may be called "Graphics Settings", "VGA Share Memory Size", "Video Settings” or something similar.

If your BIOS does not have such an option, you're out of luck.

But if the reason you wish to increase the VRAM is because a game is refusing to run, you may fake a larger VRAM by changing a registry setting as follows:

• Run regedit and position to the following key: HKEY_LOCAL_MACHINE\Software\Intel.

• Right-click the Intel folder and choose New > Key and name it GMM.

• Click the new GMM folder on the left and right-click inside the right side.

• Select New > DWORD (32-bit) Value and name the new item DedicatedSegmentSize and give it a decimal value. In megabytes, the maximum value is 512.

• You will need to reboot after setting this value.
