Connecting Acer G235H Monitor & Samsung (Model Code: LN 46A580P6FXZA) fo MacBook Air (Early) using Thunderbolt 3

I would like to make use of an Acer Monitor and Samsung 50"TV to use with my MacBook Air. The Acer Monitor would provide a larger display to conduct academic research, while the Samsung TV would be used for the purpose of steaming shows from the internet.

Here are the specifications of the MacBook Air (Early 2014), which i located under System Information:

1. Zero (0) FireWire found
2. One (1) Thunderbolt / USB4:
3. Two (2) USB 3.0

The Acer G235H Monitor connects either via USB / VGA Adapter or with a Thunderbolt / VGA Adapter. The Samsung TV connects with a Thunderbolt / HDMI Adapter. However, there is a Mini DisplayPort to HDMI VGA Adapter, Onten 4K Thunderbolt to HDMI VGA Adaptor Converter Compatible for MacBook Air/ MacBook Pro/ MacBook/ Surface Book/ Surface Pro 3/4/ (Space Gray)

It would seem the Mini DisplayPort to HDMI VGA Adapter, Onten 4K Thunderbolt to HDMI VGA Adaptor Converter Compatible for MacBook Air/ MacBook Pro/ MacBook/ Surface Book/ Surface Pro 3/4/ (Space Gray) would be the best option, but I need assistance in knowing what type of cable(s to purchase in order for the Acer to function properly, while streaming from the internet to the Samsung TV at the same time via HDMI. (Note: I am in possession of the hdmi cable connecting mini display to Samsung. I need to know what cables are necessary for the acer monitor to work adequately.

Thank you for your help.
