Information display screen system help?

Ah, my field....

All you need is a PC with a HDMI output, a HDMI splitter and cabling to each screen - be aware the maximum cable run between the computer and the HDMI splitter can only be 20 metres and between the HDMI splitter and the screens or secondary splitters can only be 30 metres. Cabling will work out around £50 a cable for decent 20m ones. The other alternative as AndyPix says is to use the Intel Compute Sticks. You can then stick the images you want to display in a folder and use a slideshow or similar program to display them.

Which ever option you choose what you would do is the following (assuming the program can be set to automatically play a list when you start it)

1) In the user account that would be running click on Start then Run and in the box type shell:startup
2) Copy the shortcut for the program to the startup folder that has just opened in File Explorer when you did the above.
3) As administrator again click on start then run and type in netplwiz
4) In the window that opens select the user account that would be running, untick the check box next to their name. You will be then presented with a dialogue to enter their password.

What will then happen is when the PC starts it would automatically log onto that user account and automatically start the slideshow application.

Cost wise assuming four screens and using your existing PC and excluding the cost of the application I would expect quotes of around £400-£600 depending on how far you wanted them to go with routing the cabling such as sending it through ducting or sticking it all in trunking. Using Intel Compute Sticks the cost works out around the same, you just save the hassle of cabling but it does make updating what is displayed a lot harder without using a wireless network and having a shared network folder on a PC which stores the images and is accessible by the Compute Sticks
