I've bought an inspiron M5110 10days back. Right from the initial stage i'm facing this problem, i.e., Video Graphics Card 7450M of 1GB video memory is being ignored even after installing appropriate drivers. This is discrete graphics card with 1GB memory and my system takes only the integrated graphics card's (6620G) memory, which is just 512MB. Due to this i'm facing a quality loss while viewing HD videos. Because of this my very purpose of buying this laptop is not obtained. As i'm in the media field I'll have work more with HQ & HD videos.
Kindly help me with a solution for this.
