Olivia Wilde as Quorra in 'TRON: Legacy'. Image by KsouthV2 on DeviantArt.com. I chose 1920x1080, since that was as high as the options went--and I'm not quite sure the purpose in that yet. But the background image on the New Tab page is 2133x1200... it does look fine on smaller resolutions too. Let me know what you guys think in the comments, it was my first try with Chrometheme.net.
