Your board is a web page, at an address like yourhall.hallboard.uk. Any screen that can open a web page in full screen and stay on can show it. Here are the usual ways, easiest first.
Our small plug-in box. It comes set up for your board and opens it by itself, in full screen, every time it is switched on. Plug it into the TV's HDMI socket, plug in the power, and give it your wifi (or connect a cable). Nothing else to do. The three-step setup sheet is printable.
A Fire TV Stick costs about £30 to £60 and plugs into the TV's HDMI socket. It opens web pages in the Silk browser (already installed on most models, or free from the Appstore).
The catch: a Fire TV Stick does not open a web page by itself when it is switched on. After a power cut, someone has to open Silk again. To make it start by itself, install a kiosk app such as Fully Kiosk Browser, which can be set to open your board when the stick starts. It is a paid app (a small one-off cost per device, so check the price). We haven't tested every Fire TV model, so try yours before you rely on it.
These run Android, so they work much like a Fire TV Stick. Install a browser from the Play Store (or Fully Kiosk Browser for a proper kiosk that starts by itself), open your board, bookmark it, and turn off the screensaver. Look for the Ambient mode or Screensaver setting and set it to Never.
Casting a browser tab from a laptop does not work well as a permanent display, because it stops when the laptop sleeps or leaves.
Most have a built-in web browser. Open it, go to your board's address and bookmark it, then use full screen. These browsers usually don't start by themselves after a power cut, and some are slow or limited, so a smart TV is fine for a trial but we'd suggest a Player or stick for a permanent display. Some commercial signage TVs have a "browser" or "web kiosk" mode that does open a set address on start-up. Check your TV's manual.
An old computer connected to the TV works well.
--kiosk https://yourhall.hallboard.uk added at the end of the target, and put the shortcut in the shell:startup folder. Turn off sleep in Power settings.chromium-browser --kiosk --noerrdialogs --disable-infobars https://yourhall.hallboard.uk when the desktop starts. (This is what the Player does for you.)An old Android tablet on a stand, with Fully Kiosk Browser, is a good small display for a hall noticeboard. Set it to always stay on, open your board at start-up and stay plugged in. An iPad can do the same using Guided Access (in Accessibility settings) to stop the screen sleeping or leaving the page.
