What sort of computer do I need to set up a public display?

John helps run a small museum, and they need a screen to show what's on display upstairs. What are the options?

I help run a small museum in a historic building, and it's hard for anyone with mobility issues to access an upper floor. To comply with accreditation requirements, we want some way to show what we have on display upstairs, using photos of exhibits and a short video.

On a recent visiting to a National Trust property, I saw a tablet in use for this purpose. If we do this, which device would suit our needs? Our budget is 200 to 250. If we could use the device for other tasks, such as word processing, that would be helpful. Is a Windows PC out of the question on this budget? How much more would we need to spend? John

You can use almost any type of computer for this purpose, from a small tablet to a large all-in-one PC. You can also use almost any operating system, including Android, Apple's iOS, Windows and Linux. The best choice will depend on your programming abilities and factors such as the amount of physical space available, and whether the device is supervised at all times.
