Hello. I have an HP Envy 750-114 Desk Top with an Intel® HD Graphics 530 display adapter. The desk top only has two HDMI ports and I would like to run three monitors. I have researched the display adapter and it is capable of running three monitors. I purchased an HDMI to USB adapter for the third monitor, but it does not work. Through further research I found out that my particular display adapter will not work via a USB port. Do I have any other options? Thank you!
