Got an Inpspiron 531 from Dell Outlet, with onboard graphics. When connected via VGA to 50" 1080i HDTV it will only display as 4:3. Think its 1024x768. Wondering why this is the case. Is it because onboard graphics card will not be up to the job, or do I just need to connect using DVI (with an HDMI addaptor) to TV?
Here's the tech details http://www1.euro.dell.com/content/products/productdetails.aspx/inspndt_531?c=uk&cs=ukdhs1&l=en&s=dhs
If I need a new graphics card, will I need to replace PSU - I'm not a gamer?
