9440 Dual Display using different refresh rates
Hi all. I have a 9440 2-in-1 with the Iris XE graphics onboard. I'm using a WD22TB4 dock with 2 S2725QS monitors and cannot achieve 4k with 60hz refresh on both displays. One goes at 60hz while the other defaults to 30hz. I can manually set it to 59.95 through Windows 11, but it looks grainy and not clear.
I swapped this laptop out for a work issued 7450 that has the vPRO processor /onboard and it works fine. The 9440, that i know of has TB4 ports and should have no problem pushing these displays.
