T430s, no discrete graphics - can this drive QHD (2560 x 1440) monitor?

#1 Post by serpico » Thu Dec 24, 2020 2:12 pm

Relative of mine has a T430s with Intel HD graphics only. Wondering if this can drive a QHD (2560 x 1440) monitor while also driving laptop screen?

Still NOT a great day for a Guinness! (the Real Black Stuff).

QHD is not 4K. According to the Tabook, the T430s supports up to 2560x1600 through the mini-DisplayPort, but not through DVI on the dock (the DVI is limited to 1920x1200 as it is single-channel).
