[hdryx]

Hi,

I'm planning to buy a new laptop with these specs (i5 / i7 haswell, 1TB hard drive, 8GB ram, 740m / 820m / 840m graphic card). I have to choose between these 4 laptops that have similar specs, but i don't know which one of them has the best screen / display quality :

1 : Lenovo IdeaPad Z50-70

Does any one else have an opinion on that?
