@Obsydian: Can you let me know the full model number of your monitor, along with the model number of the Multiport Adapter you're referring to? Some M70A monitors support wireless DeX, so you may wish to consider this as an option if you wanted to keep some of your ports free for other connections. Please keep in mind however that your mobile device will also need to be wireless DeX compatible. Although I'm not certain, if you have an external device that supports 4K @ 60Hz then you are better off connecting it directly to the HDMI port on the monitor, as it may not be possible to hit those specifications when passed through the USB-C adapter.
I'm having trouble with my Multiport Adapter ee-p5400 (connected to a Galaxy Book2 Pro360, the HDMI port doesn't seem to work, nor connecting a USB-C to HDMI cable between the adaptor and the monitor.
Primary reason I got this adaptor was so I could have 1 connection to my laptop that i needed to disconnect, but it seems like I still need to have most of the USB-connectors plugged into my laptop.
Can someone confirm if there are limitations with this multi-port adaptor I have been unable to find a detailed spec or manual for it which might indicate if there are some limitations (e.g. the HDMI port only works with some laptops, or some phones, or certain screen sizes).
