Triple Monitor Viewing Problem

[clei]

My HP laptop (model 17z-ca000) performs poorly when connected to my two HP monitors to provide a 3-way monitor setup.  I am puzzled as to the cause since my older Dell Inspiron laptop (model 5559) performs perfectly in this same 3-way setup.  Specifically, the problems I have with the HP 17z-ca000 laptop are as follows:

1. Viewing of the monitors, all three, become erratic and unreliable, with connection popping in and out.
2. Mouse functions poorly.  It staggers and stalls as I try to point it around, making my work painfully slow and difficult.

I am using Windows 10, 64-bit, home edition, updated to current version.

My connectivity device is a GREATHTEK KVM Switch HDMI Dual Monitor extended display 2 port 4 USB 2.0 hub.

I would greatly appreciate hearing from community/forum members who may have suggestions for fixing this problem.

Thanks.

Your machine is a CTO machine, it should have same ports as the following machine:

I don't think the GREATHTEK KVM Switch HDMI Dual Monitor would give you to view 2 monitors at the same time. All you need:

M1: notebook screen,

M2: HDMI direct to monitor,

M3: DisplayLink Certified USB-A to HDMI adapter such as
