Digital Signage

Requirements for digital signage

  • A person to create & update the content.
  • A location that is accessible for your audience but where a TV and a delivery device can be securely mounted.
  • You must coordinate with facilities to:
    • Ensure the location you've chosen can support the weight of the TV and can accommodate the required power and cables. Power and cable requirements will differ, depending on your choice of device to deliver the content (see below).
    • Schedule the installation of the digital signage.
  • TV or monitor that's recommended for digital signage use. LIS can advise on TV size once the location of the sign is identified.
  • Device to deliver the content. Some options include:
    • a computer with wireless keyboard and mouse (recommended),
    • USB drive -- very simple, but with some caveats (see the USB drive section below)
    • DVD or Blu-ray player -- high quality but slow
    • commercial digital signage player -- expensive, more complex to purchase and configure
  • Software to create & update the content. Some options include:
    • PowerPoint - easiest to use, but comes with some caveats (read the next sections for more info)
    • any video editing software - high quality, slower and more complex to use
    • commercial digital signage software - expensive, more complex to purchase and configure

Choosing a TV

Once a location for the sign is identified, LIS can recommend an appropriately sized TV and mount that is suitable for digital signage use. We recommend specific commercial-grade TVs that include features such as 24/7 operation and automatic power saving. If cost is an issue, from past experience we can recommend specific 50" Sharp TVs which seem to hold up well and are lower price than a commercial-grade TV. Consider that commercial and power saving TVs are highly recommended to ensure that your TV will last 3-5 years. You may consider using a cheaper (consumer-grade) TV without commercial & power saving features, but keep in mind that such a TV may fail sooner if it's used for digital signage (i.e. if it operates 7+ hours per day). Also keep in mind that TV repairs are costly and LIS can only provide basic repairs that cost less than $100.

Once you've identified the location and the desired screen size, you will need to work with facilities to mount the TV and provide the required power and cabling.

We recommend that you provide us with your index number so we can make the purchase for you. This way, we can more efficiently tag the screen, insert it into our inventory for security & budget tracking and we can better process the delivery, installation and configuration. You should also include TV funds into your annual budget - your department is responsible for repairs more than $100 and for replacing the TV every 5 years or when it fails beyond repair.

Choosing a device to deliver the content

There are several options for selecting a device to deliver your digital signage to the TV: computer, USB drive, DVD or Blu-ray player, commercial digital signage player. Pros and cons are discussed in the sections below.

Using a computer to deliver the signage

From all the options for a device to deliver the content, we recommend that a computer be purchased and installed near the TV. You should also think about whether a Mac or a PC is better for your digital signage needs - choose the operating system that the person who'll be updating the signage is most comfortable with. The computer should have the standard Microsoft Office software - there are no other special software requirements.

There are different physical requirements for the computer, depending on what location is chosen for it. You will need to work with facilities to mount the computer and provide the required power and cabling. Review the options below before speaking with facilities:

  • Install the computer in a nearby room. The room must be secure from theft but accessible to the person who will create and update the content.
    • Conduit for wires: If the TV is within 45 feet of the computer, one HDMI (combined audio & video) wire will need to be run from the computer to the TV. HDMI wires have a length limit of 45 feet. For distances greater than 45 feet, different wires can be used with special transmitters, but this will increase the cost of the sign by $900.
    • A second (smaller) 16:9 computer monitor may be required if you cannot see the TV from where the computer is.
    • Duplex power outlet required.
    • One wired network outlet (highly recommended).
  • Install a small computer behind the TV using a secure mount
    • A secure wall mount is required ($40).
    • A wireless keyboard and mouse is recommended ($50). You will need the keyboard and mouse for a brief amount of time when you update the signage.
    • One power outlet
    • One wired network outlet (highly recommended).
  • A shelf under the TV that can be used to securely install the computer.
    • A cable or mount is required to securely install the computer on the shelf ($40).
    • A wireless keyboard and mouse is recommended ($50) though wired ones can be used on the shelf. You will need the keyboard and mouse for a brief amount of time when you update the signage.
    • One wired network outlet (highly recommended).

Using a USB drive to deliver the signage

Using a USB thumb-drive instead of a computer is possible but may be a bit challenging for the person who will be creating the content for the signs. The TVs cannot natively run a powerpoint slideshow from a USB drive, but can show pictures or video files from a USB drive. Powerpoint can export the slides to a USB drive in two formats: as picture files or as a video file. Pros and cons of each approach are discussed below.

Exporting as a picture file to the USB drive

We've found that powerpoint for Windows cannot export the slides in the TV's maximum resolution (1920x1080). So if you use a Windows computer to create the signage, your signs will not fill the entire screen. However, we've found that powerpoint for Mac can successfully export the slides in the TV's maximum resolution. You can check the instructions below to see if you are comfortable with using a Mac to create the powerpoint.

Exporting as a video file to the USB drive

We've found that powerpoint for Windows can successfully create a video file that plays back on the TV in full screen. However, the quality of the video file exported from PowerPoint (480p) is less than the capabilities of the TV (1080p), so you won't be getting the maximum quality. If you're OK with this, you can review the instructions below for exporting a powerpoint as a video file.

You can also use a video editing software such as Apple iMovie or Windows MovieMaker to create your signage as a very high quality video file. This may be good for high profile signage that does not need to be updated, but it is a very slow process if your signage will need to change.

Using a DVD or Blu-ray player to deliver the signage

You can also use a DVD or Blu-ray player as a device for delivering the signage. For this, you will need to use video editing software such as Apple iMovie or Windows Movie Maker, along with disc recording tools to create a DVD or Blu-ray video of your signage. This may be good for high profile signage that does not need to be updated, but it is a very slow process if your signage will need to change.

Using a commercial digital signage player to deliver the signage

A commercial digital signage player is also an option, but it is expensive and more complex to purchase and configure. LIS can discuss this option further.

Cost Estimates

The final project cost depends on the cost of facilities & contractor work, the size of the TV as well as the device and software for creating and delivering the signage. Please read the sections above for more information on what your options are. A typical 50" TV with a computer will cost about $1450 if you choose to use PowerPoint and you mount the computer behind or under the TV. If you are willing to use a USB drive instead of a computer, the cost of a 50" TV and all other hardware (everything except the facilities work) is closer to $650.

1. Facilities work is required to mount the TV and other hardware, and provide power and cable runs. Contact facilities for an estimate.

2. TV costs: 50" LED TV with a secure mount offers a good size vs price ratio at around $780. Other options range from at least $500 for a 42" commercial display up to $2000 for 70" TV. A universal secure mount will cost about $150.

3. Device to deliver content (choose one):

  • Option 1 - Computer: $500-$900 depending on model
    • Wireless keyboard and mouse: $50 (optional, but easier for updating signage)
    • Additional monitor: $200 (required if the computer is installed away from the TV and you can't easily see menus)
    • Secure mount: $40
    • Lock: $20
    • Shelf: $40 (optional)
  • Option 2 - USB drive ($20 or less but read the USB drive caveats above)
  • Option 3 - DVD or Blu-ray player: $200 but is slower and requires the use of video editing software & disc recording tools)
  • Option 4 - commercial digital signage player: Similar to Option 1 costs but requires digital signage software and server which are additional costs in the range of thousands of dollars plus annual support contract fees.

4. Audio & video cabling (choose one):

  • Option 1 - If computer is installed under or behind TV: $0 (we will use the HDMI cable provided with TV)
  • Option 2 - If computer is within 45 feet of TV - long HDMI cable: $50
  • Option 3 - If computer is more than 45 feet away from TV - transmitters & cabling $900

5. Software: PowerPoint software and video editing software $0 (provided for free through the College). If you'd like to look at commercial digital signage software, please keep in mind that this will be in the range of thousands of dollars plus annual support contract fees.

Software instructions for creating & delivering content for digital signage

General Recommendations

  • When inserting pictures in your signage, please use high definition files (with a width greater than 1000 pixels or a height greater than 1900 pixels). Click here for more information on how to find the dimensions of an image in pixels.
  • Use font size 34 and above.
  • Consider the colors of the background and text. You may want to consult with the communications office for further guidelines.
  • Other design resources: Digital Signage Backgrounds: Often Seen First and 6 Design Tips for Digital Signage
  • We recommend using PowerPoint on Mac to create the digital sign because it can export slides in 1080p (full HD). PowerPoint on a PC exports slides in 720p (see 720p vs 1080p for more info)

Delivering signage using a USB drive - instructions for preparing content using a Mac

You will create your signage using a Mac and powerpoint (just like creating a regular presentation) and you will export your slides as a series of JPG pictures that the TV can show without a computer. At the end of the process you will have two things: a powerpoint document that serves as your presentation source and a folder with JPG pictures created from the powerpoint document. The folder with pictures goes on a USB flash drive that can be connected directly to the TV without a computer. You keep the powerpoint document on your computer or server so you can easily make future updates. Note that any PowerPoint transitions, animations or video clips that you insert will not display on the TV, though the TVs do support basic transitions such as cut, fade, dissolve. The pictures will be exported in 1080p (true HD, which matches the quality of most new TVs).

  1. Login to a Mac that has powerpoint. You can use your own or one of the Macs in the Library.
  2. Check that PowerPoint is setup to create & export the slides at a resolution of 1920x1080:
    1. Click File => Page Setup and next to Slides sized for select On-screen show 16:9.
    2. Click on the PowerPoint menu in the top left and click Preferences > Save
    3. Select the Save every slide option
    4. Set Height to 1920 and Width to 1080
  3. Create or update the slides as needed. Insert any pictures, shapes or text. Note that any transitions, animations or video clips that you insert will not display on the TV.
  4. Plug in the thumb drive
  5. Click File => Save as Pictures
    1. Under format choose JPEG
    2. Choose the flash drive as a destination and type a descriptive name in the Save as box on top.
  6. Connect the thumb drive to the TV.
  7. Use the TV remote to select the USB drive and select the folder with your pictures.
  8. Select the first picture and use the TV remote to set the TV to loop the pictures (Repeat All).
  9. You can also change the transition speed between slides to Short (~3 secs), Medium (~5 secs) or Long (~30 secs).

Delivering signage using a USB drive - instructions for preparing content using PC

You will create your signage using a PC with powerpoint (just like creating a regular presentation) and you will export your slides as a video file that the TV can show without a computer. At the end of the process you will have two things: a powerpoint document that serves as your original (source) document and a WMV video file created from the powerpoint document. The video file goes on a USB flash drive that can be connected directly to the TV without a computer. You keep the powerpoint document on your computer or server so you can easily make future updates. Note that most PowerPoint transitions and animations will transfer over to the exported video file. The video file will be in 720p definition (not as high def as most new TVs).

  1. Login to a PC that has powerpoint. You can use your own or one of the PCs in the Library.
  2. Check that PowerPoint is setup to create & export the slides in decent quality:
    1. Click the Design tab and click Page Setup. Next to Slides sized for select On-screen show 16:9.
    2. Click File => Options => Advanced

  5. Plug in the thumb drive.
  6. Click File => Save as and under Save as type select Windows Media Video.
  7. Click Save. This will take a longer time if you have many slides.
  8. Choose the flash drive and type a descriptive name in the file name box near the bottom
  9. Connect the thumb drive to the TV.
  10. Use the TV remote to select the USB drive and select the video file option.
  11. Select the video file and use the TV remote to set the TV to loop the video (Repeat One).

Delivering signage using a computer connected to a TV - instructions for preparing content using a PC or Mac

These instructions will help you create digital signage using your computer. You will create a powerpoint file that you can transport to the computer connected to the digital signage TV. At the end of the process you will have two things: a powerpoint document that serves as your original (source) document and a powerpoint "show" created from the powerpoint document. The powerpoint "show" needs to be opened on the computer that's connected to the TV. You keep the original powerpoint document on your computer or server so you can easily make future updates.

  1. It is recommended that you create the powerpoint slideshow on the same platform as the computer that will be used to deliver the signage (if you have a PC connected to the TV, use a PC to make the signage).
  2. Check that PowerPoint is setup to create & export the slides in the correct aspect ratio: Click the Design tab and click Page Setup. Next to Slides sized for select On-screen show 16:9.
  3. Create or update the slides as needed. Insert any pictures, shapes or text.
  4. Click the Transitions tab and under Advance Slide, place a check mark next to After. Use the up and down arrows to set the delay between slides.
  5. Click the Slideshow tab and click Set up show.
  6. Choose Browsed at a kiosk (full screen).
  7. Under Slides click All and under Advance slides click Using timings, if present. Click OK.
  8. Click File => Save as
  9. Under format select PowerPoint Show and give the file a descriptive name.
  10. Bring the PowerPoint "show" file that you saved in the step above to the computer that's connected to the TV.
    1. Remember to bring over a keyboard and mouse (in order to prevent unauthorized access, we recommend that you do not leave a keyboard and a mouse with the computer that's connected to the TV).
  11. Open the PowerPoint show file. Powerpoint will automatically advance slides and will loop until the Escape key is pressed.
