Hi, I’m Nicole, I’ll be happy to help you out today.
Based on my experience, it is not advisable to use a splitter especially if you are going to set the displays in extend.
Instead, connect the first monitor directly to the HDMI slot of the laptop then use a USB to HDMI converter for the 2nd display.
You can also use a display hub so you can manage the displays much better.
