Slightly off-topic, but might be good to know:

Connecting both the BenQ monitor (with a DVI cable) and the Philips monitor (via a DisplayPort cable) to the same PCIe card (NVIDIA PΛLiΤ GeForce GTX 1660) works around the original problem (so now both monitors show proper contents in the Join mode, and I can move windows between them). However, I don't hear sound from the speakers of the Philips monitor this way.
