For higher refresh rates and resolutions, replace the DisplayPort 1.2 MST Hub with a DisplayPort 1.4 MST Hub (such as the CSV-7300 or CSV-1550). Then you can connect your MST Hub to that. For your laptop which supports DisplayPort 1.4, I would choose the CAC-1567. So what you need is a USB-C to DisplayPort adapter (such as the CAC-1507, CAC-1567). The specs for the HP Pavilion Gaming Notebook with a Nvidia GTX 1660 Ti atġ SuperSpeed USB Type-C® 10Gbps signaling rate (USB Power Delivery, DisplayPort™ 1.4, HP Sleep and Charge) HDMI to DisplayPort adapters cannot do MST to multiple displays. To connect HDMI output of computer to DisplayPort input of display, you need a HDMI to DisplayPort adapter (such as the CAC-1330, CAC-2330, CAC-1331, CAC-1332) DisplayPort to HDMI adapters (such as the CAC-1056, CAC-1070, CAC-2070, CAC-1080, CAC-1085) only work in one direction (DisplayPort output of computer to HDMI input of display).
