Envy 17 Touchsmart Screen Resolution

Before purchasing the new touchsmart envy 17 i called sales who confirmed it was full hd resolution 1920x1080 (the website doesn't state it).

The box also stated "Full HD".

However having switched on the machine the highest available resolution is 1600x900 ?

Can you advise or help? 

Thanks.
