Hello, I just purchased and installed a DL 7400 Displaylink adapter. I have. total of 5 external monitors now working with my M4 MacBook Pro equipped with the M4Pro chipset. 2 monitors are connected natively but 3x32" 2k monitors are connected to the new Displaylink adapter (1 by HDMI and 2 by DP). I have them all running at their max refresh rates which is 75hz on 2 of them and 100hz on on the other. The 100hz one uses the HDMI connection because that monitor only has a DP and USB-C port. I have been told to only run them at 60hz but does that advice only apply to the older Displaylink adapters with the DL-6XXX chips and not the new ones equipped with the newer DL-7400 chip?

Also, Wavlink has a different looking driver for this adapter on their website but I am using the latest generic driver from the Synaptic site. I assume I am using the correct one?
