USB-C to HDMI adapter connect with DisplayPort

I have a Macbook Pro 13" 2017 ( no touch bar ) and an external display Dell2214H I bought an USB-C Digital AV Multiport Adapter but did not notice that Dell2214H only has DisplayPort. That so, I have to buy another HDMI to DisplayPort adapter, but the display does not work when I connect to my MBP. I'm not sure it is because of the setup ( USB-C Digital AV Multiport Adapter -> HDMI cab -> DisplayPort adapter -> external Display ) does not work or not. There is no USB-C to DisplayPort in Apple site, maybe MBP 2017 cannot output to DisplayPort? What should I do next to make my Dell display work? Note: - I tried my MBP with USB-C VGA Multiport Adapter and it works correctly. But the display quality is not really good, that why I want to make it work with DisplayPort - I checked the version of Adapter driver, it is the latest version ( 2.33 ) already. - Dell2214H display
