How do I check my switchable graphics?



I have a Lenovo IdeaCentre B320 running an Intel Core i3 2120 processor.
I was told that my machine would be delivered with AMD Radeon 6450 discrete graphics (6450M perhaps?), with 1 Gb of dedicated memory.
Device manager and DirectX show only Intel HD 2000 (i.e. integrated) graphics, with 64 Mb of dedicated memory.
Lenovo tell me that I have switchable graphics and that the discrete graphics automatically come into play when I do something graphics intensive.  I can see no evidence of this from Device Manager whilst running videos or by looking at the BIOS options.
How do I check that I have the AMD graphics and that this switching properly occurs?
Many thanks,

Re: How do I check my switchable graphics?

Hello rcmundy and welcome to community,


B320 All in one comes with Intel HD Graphics 2000 or ATI RADEON HD6450 1G


Can you share the system serial number or machine type via private message so the detail on graphic card can be check.


Best Regards,
