ot sure what you or the agent is saying
hotspot is wifi to laptop or tablet etcc.
HDMI is video and sound signal, not internet
usb tether or hotspot wifi you are using Data
the HDMI cable to the TV does not change the amount of data
BUT HDMI from phone to TV , can change how you are 'billed' depending on your phone plan
She explained that the quality of the signal is not as good when connecting from the laptop via HDMI. I have a problem telling the difference. I do know that prior to having a smart tv in the rv I streamed to my laptop and fed the signal to the tv through the HDMI. I never got the shocking amount of data use that I got from direct streaming to the smart tv.
