I bought T440s (windows 7 pro) with FHD WWAN screen and I am noticing that my older T430s (windows 8 pro) has a clearer and brighter display. Both have the same Intel controler (Intel Graphics 4400). Screen colors on T440s are warmer (yellowish) than on T430s which has whiter and more appealing/cleaner display/colors.
T430s explicitely shows Intel(R) HD Graphics 4400 in the device manager while the new T440s shows Intel(R) HD Graphics family only. There is no reference to to 4400 although my order information shows Intel 4400.
Could someone please clarify how this display difference is possible. Should I check with tech support if I received a less quality hardware on my T440s.
