Multi-Monitor Setup using Laptop

Hello,
I want to connect my Lenovo laptop to TWO Dell monitors, so that will be 3 screens in total including the laptops screen. However I only need the laptop to act as a PC, I don't need its screen.
As my Lenovo laptop only has a single HDMI output I purchased a Techole HDMI Splitter (Model: HS306) to enable me to connect to both Dell monitors.
The problem I have found is that I cannot get the 2 Dell monitors to be the main displays that can both display 2 different windows applications at the same time, e.g. MS Word on one monitor and Gimp on the other monitor, even with the laptop screen OFF. I only seem to have the choice of:
1) Laptop screen only.
2) Laptop showing MS Word + 2 Dell monitors showing Gimp.
3) Laptop screen OFF + 2 Dell monitors showing identical applications.
It may be that Windows 10 only seems to detect 2 monitors, 1 for the laptop, and 1 for BOTH Dell monitors. Or it may be that the Intel(R) UHD Graphics 620 on-board graphics chip does not supports enough monitors.
If anyone knows what could be going on please let me know. The image below shows exactly what I am trying to achieve.
Many Thanks.

An HDMI splitter is a simple device. It simply takes a single HDMI output and replicates it so that two monitors can display the same thing. It cannot be configured as two separate displays showing two different things.

How have you got the "display settings" set up? Does windows detect there that there are 3 devices e.g. your laptop + screen 1 + screen 2?
I use "extend display" with my laptop + 1 screen with the bigger screen as my "main display" but i can have different windows open (and maximised) on each with different applications running e.g. email on one, and MS Word on the other - does that offer the functionality you need?0 -

OP - you need to confirm what model your laptop is so that people can advise. There are a few box of tricks that allow two monitors to connect to one HDMI port and show unique content (though your computer will still show it being connected to one monitor but an ultra widescreen one) but their cost is north of £100 and therefore there may be cheaper options depending on what ports your laptop has.0 -

I have gone through all the display options listed below (results shown), however it may be the on-board Intel(R) UHD G620 Graphics chip or its driver (version: 26.29.100.7323) that is causing the problem.

Get a docking station. There are loads of cheap Lenovo docking stations on ebay. Make sure the dock allows you to use 2 digital video outs simultaneously - some of the older ones only allow you to use one analogue and one digital simultaneously.

A cheap(er) option might be to try a USB C to HDMI cable - or just name the model of laptop so others can confirm whether the C can output video.0
