PC help please

I currently use a 15' screen Sony Vaio laptop and can play up to 4 Ladbrokes/Prima tables at once, set on max screen resolution of 1400x1050, with the tables set to 'normal view'. There is an overlap of the tables and i miss some of the action/screen notes.

I am going to get a new one, again I would like the portability of a laptop, rather than a desktop. Budget up to £2k if necessary. Found a nice 17' widescreen HP one today and played around with it in Comet. Although it had resolution settings up to 1900x?, when i fired up 4 tables the overlap was worse than on my current kit.

Anyone out there got any recommendations/suggestions please. (i recall seeing some posts on this subject sometime back, but cannot locate them)
