Beginner Help

Just trying to start out.
I’m using my own bike (a mountain bike).
CooSpo Cadence and Speed Sensor Cycling RPM Sensor Bluetooth ANT+ for Bike Compatible with Zwift

I want to use either a computer monitor or a tablet or an Android phone

What exactly do I need to do and are there any specs I need to look for in my Android tablet or phone to use Zwift. Can I actually use a computer monitor instead?

Is there anything else I need to buy?

Thank you for your help

Are you using an Android phone to run Zwift?
You can cast the phone screen to a smart TV or use a Firestick ,Roko ECT.
There is a slight lag on the screen.
I prefer to use a laptop and use a HDMI cable between the Laptop and TV.
Laptop and Android phones are the only devices I have used.

Is your phone compatible with Ant+?
Are your sensors Ble and Ant+?

The answers to these questions will will dictate which options are available to you.
