Dell XPS 15 Screen Upgrade

Hi there, I purchased a Dell XPS 15 from JB Hi-fi not long ago

and realised recently that the screen is not full HD.

Im kind of dissapointed for the price it was and expected it to be full

HD due to the information given in youtube videos and the USA Dell website where the

bluray combo had the full HD screen. Well this is New Zealand I guess.

Anyhow, I was wondering if it is possible to get a upgrade to (1980 x 1080) resolution

screen.  And if so how much would it cost.

Thanks,
Jason
