Yes there are HDMI splitters and I personally use this one: https://www.amazon.com/Proster-Splitter-Converter-Projectors-Supports/dp/B01M24KTBA/ref=sr_1_9?ie=UTF8&qid=1497855050&sr=8-9&keywords=female+HDMI+splitter
I would say getting a HDMI would be your best choice as VGA is obsolete. HDMI cables aren't too expensive on Amazon at this link: https://www.amazon.com/HDMI-Cables-Video-Interconnects-Accessories/b?ie=UTF8&node=202505011 . Hope I helped!
