Can video stream from USB port on cell phone to TV via HDMI?

if your using a roku, then you are not streaming video from the phone
you are using the phone as a hotspot for the roku

you need to download and app to 'mirror'/'cast' your phone to the TV
and stream video using the phone

this still depends on your 'phone plan' having 'video service streaming' FREE as part of your plan

with out the free video streaming , nothing you do is going to reduce data usage

My phone plan doesn't limit normal data but it limits the Hot Spot data to 15G, then drops it to a useless 600kbps.

Have a read HERE.

OP back,

Just checked advanced specs on the phone and the mini USB doesn't have video out....which I'm assuming is necessary to get video through a HDMI cable to TV.

My phone is a LG k20 with a traditional mini USB plug.

So I'm using a Roku Box and Chromecast to get video to the TV, but they will only work when attached to local wifi network. Hence the need for Hot Spot and when your watching HD movies that 15 G doesn't last long.

Just came back from Walmart and they didn't have the right cable.

Only if you are 'streaming' prerecorded media from your phone.

If that's the case its likely easier to just put it on a thumb drive and plug that straight into the TV directly.

If it's 'streaming' from somewhere o the internet, data usueage is involved.

What phone?
The phone spec info, in the manual or online will tell, if the phone has media port capability

But I doubt that will change your data usage
You are still using cellular data to stream the video to your phone
If you have a phone plan that includes video streaming to the phone
Then your allowed data will not be used, when bring cabled connected to the tv

Depends on the phone. IIRC not all of them can output to HDMI from mini USB/micro-usb. Most Samsung devices can.

Look here:

I can with my Iphone 8 and my Ipad using Apples' Lightning to HDMI adapter.

YES. I'm not so sure about data quanities but you can get a USB (Phone) to HDMI adapter at most cell stores. Best Buy. Amazon... I may even have one lying about but frankly do not know where.. just google: mobile phone to hdmi adapter

I just did lots and lots of hits.

Not if it is an older (non-smart) flat screen TV. Maybe that's part of the question?
