Is there a way I can show a message from a node on a display?

What sort of display? Do you mean in a browser? If so then if you are using the node red dashboard you can use the notification node.

Do a search of installable contribs... might be one that does what you want.

Also try I2C (if your display supports that) or OLED if you have that type.

I think it may be similar to an HD44780 style connection - If so then the older [node-red-node-pilcd (node) - Node-RED](https://flows.nodered.org/node/node-red-node-pilcd) node may work.

Did you see this on the node's flow page

> Requires the RPi.GPIO python library version 0.5.8 (or better) in order to work.

Do you have it installed?
