Any standard Windows, Mac, Linux computer should work. You can also use Google TV and Amazon Fire TV devices along with Raspberry Pi (4 or above) units for neat and discreet deployments.
You do not need special hardware, nor do you need to buy anything from us, you can use any old machine you have laying around.
There are no minimum hardware requirements, although we would recommend at least a dual core processor and 4GB of RAM for basic use, and higher for things like dashboards and reporting displays that tend to run a lot JavaScript and perform CPU bound animations.
Please see the following post for a description of common hardware and use cases for TV dashboard setups: https://www.vuepilot.com/support/article/hardware-requirements/
