This is not an issue with the monitor driver. Monitors don't need drivers. This is either a hardware limitation on the computer or a graphics driver issue. I need to know what video card or GPU you have to know for sure. What is listed under "Display adapters" in the Device Manager?

Is the MacBook Pro the same computer you're having the issue on with Windows 10? There hasn't been a dual-link DVI port on a MacBook Pro since 2007, and that model doesn't have DisplayPort or HDMI, so I'm confused about what you have.

It's quite possible the DP functionality of the monitor does not work at all. I am able to get the full resolution if I use a DVI-to-DVI connection from a MacBook on OSX (no virtual machine).

Two Lnovo laptops with Windows 7 & 10 recognize the name of the monitor in the Device Manager, but when attached to DVI, whether via conversion from DP (with a passive adapter) or via HDMI-to-DVI, the highest selectable resolution is 1280 x 720, like the thread linked in my original post describes. The Lenovo X1 Carbon (gen 4) is using only the native Intel GPU, and a Lenovo T430s has an NVIDIA chip (NVS 5200M). Neither have any luck with higher resolutions on the HP monitor.

I have a docking station for the T430s that has DVI out. I will have to try that out.

Incidentally, I know it is not my DP cable, since I can get it to work with other monitors.
