Dual External Singer's Monitors

[xxyzz]

I purchased a HDMI splitter and output the laptop to the splitter then ran one output to my 55 inch LG TV and my 15 year old Dell Monitor to the second output. I have Windows 10 in the extend display option. I am only getting a picture on the LG TV and nothing on the old Dell monitor.
This monitor has only a VGA port and I have been using it previously with a VGA to HDMI cable and it works fine by itself just not with the splitter. Do you think the problem is I need a newer monitor that has a dedicated HDMI port or am I not sitting the display options in Windows correctly.
Here is the specs for my splitter
