Since you are using a splitter the port is receiving only one signal.  That means that both monitors receive the same signal.

Have you thought about a port repeater?  I have a couple for my Lenovo laptops.

Hi OctoberxSoldier
I am Vijay, an Independent Advisor. I am here to work with you on this problem.

Take actions related to Display Driver as the first level of troubleshooting
Windows Key+X > Click Device Manager > Expand Display Adapter > Right click on entry below >

A. Rollback the Driver
Click Properties > Go to Driver tab > If there is rollback option, click it

B. Update driver from manufacturer's website
Go to the website of the driver's manufacturer or computer's manufacturer > See if some driver is released for your model and OS > If yes, download that > In previous option, click Uninstall > Install the downloaded driver > Restart your computer

You will need to restart your computer after the above steps.

Do let me know if you require any further help on this. Will be glad to help you.
Sincerely yours,
Vijay A. Verma @ https://excelbianalytics.com
