On this page we present a broad overview of the digital signage hardware solutions that are available. This information aims at users that want to implement a professional digital signage solution by themselves and who desire a holistic overview that covers all relevant details. Apart from the right digital signage software (FrontFace for Public Displays and FrontFace for Touch Kiosks), you have to choose the right screens, mounting facilities and appropriate player PC hardware. Also, the type of installation can vary based on the selected components (e.g. different types of cables, etc.). Which components and which setup you choose depends on what you actually want to achieve, on the options you have at the physical installation location and on your budget.
We offer here a holistic overview that will allow you to find the right solution for your individual application. Furthermore, we provide some contact information of vendors where you can obtain the necessary components.
Which screens / displays can I use?
Virtually any screen, display or TV set can be used. This includes common PC screens, consumer TV sets (TFT/LED or plasma) as well as professional LFDs (large format displays). Consumer devices such as common flat screen TVs are usually very cheap but are not (at least not officially) certified for 24/7 operation. In case 24/7 operation is a requirement for you, you should choose a professional flat screen device that is certified for this type of usage. Companies like Samsung, LG or Panasonic offer these displays for professional applications. Whether you choose a professional (but more expensive) screen or less expensive consumer device depends on how much money you want to spend and if want to run the screen for more than 8 hours per day.
Some TV sets are called "Smart TVs". This means that apart from the common TV/display functionality a small computer is integrated that offers features like Apps, video streaming/playback or sometimes even a Web browser. However, these Smart TV features are not sufficient for professional digital signage – you will always need a separate player PC that is connected to your screen. Also digital picture frames cannot be used since they generally have no interface to connect to a PC.
What is a player PC and why is it needed?
A screen/display/TV alone is not sufficient for digital signage setup. In order to be able to display content on your screen, you also need a PC that is connected to the screen on which the FrontFace Player Application can be installed. This player PC can be any common Windows PC, a notebook computer or a compact mini PC i.e. a small form factor PC, often also called a "thin client"). Technically, a mini PC is a normal Windows PC but at a very small size for convenient mounting behind the screen. A mouse and keyboard are not really required for this PC because the FrontFace Player Application that starts automatically will take over the PC; and administration and content management is done remotely from another PC using the FrontFace Display Assistant-Software. In everyday use, only the power switch of the PC will be used. However booting and shutdown can be automated as a scheduled task!
There are also professional screens available that have a bay in the chassis where a mini PC can be plugged in or that have a PC already built-in. In case you only want a small screen (~ 20”) you can also use a so-called All-in-One PC. This is a PC that has the PC hardware integrated into the chassis of the monitor.
How many screens can be connected to a player PC?
Generally speaking, you can connect as many screens as you want to a player PC as long as the graphics adapter offers the required number of interfaces. There are special graphics cards that support up to 10 screens at a time that can all be addressed individually. The FrontFace software allows you to display the same or different content on the connected screens. It is important to note that the more screens you use with a single player PC, the more computing power you will require in order to get smooth animations and consitent video playback! Otherwise the playback performance of multimedia content may be affected. Therefore dedicated player PCs are generally used for every screen – especially when these screens are located at several separate locations at the site.
Apart from normal screens (TVs or monitors), FrontFace also supports addressing video walls. This includes segmented video walls which consist of multiple screens that are combined to one large picture as well as special LED matrix video walls that are typically used for outdoor applications. Please see here for more details about video walls...
How do I connect screens and player PCs?
In most cases a cable is used for connecting the screen and the player PC. Which cable you must use depends on the interfaces/connectors that your screens and player PCs offer.
Most flat screens and TVs use HDMI– so you will need an HDMI cable. Other standards that are common are e.g. VGA, DVI, DisplayPort and Mini DisplayPort. There are also adapters available that you can use to make the different types of cables and connectors compatible to each other (e.g. HDMI to DisplayPort). Depending on the type of cable being used, you can bridge different distances with that cable:
- HDMI(up to 5 meters, max. is 15 meters (with high quality cables))
- DVI (max. is 10 meters)
- DisplayPort and Mini DisplayPort (up to 15 meters)
- VGA (up to 30 meters, but only with high quality cables)

How can I bridge larger distances between player PCs and screens?
If you cannot mount your player PC directly behind the screen or at least close to it, there is another, inexpensive way to bridge larger distances: so-called CAT extenders. This is a special adapter device that transforms a connector/cable type like HDMI into a signal that can be transferred over a common CAT-5 or CAT-6Ethernet network cable (twisted pair). In many scenarios these kind of cables are already installed and can easily be used for this purpose without having to lay out new wires. Depending on the type of cable and which CAT extender you choose, you can bridge up to 100 meters. Distances of 20-50 meters can be managed with most CAT extenders using normal CAT-5 wires. The only thing you have to take into account is that you cannot use such a cable for networking AND for the CAT extender. You have to use a separate cable that is not used for anything else.
Apart from the CAT extenders, there is signal amplification available for connector/cable types such as VGA, which also allow a larger distance. Additionally, there are also wireless solutions available, however these cannot bridge very large distances and they often are prone to interference.
How can a screen be mounted?
Flat screens usually have a built-in mounting facility called VESA. These are standardized screws at the back side of the screen that can be used to securely mount the screen to a wall mounting device. The size of the screws differs based on the size and weight of the screen. There are many vendors that sell wall-mounting equipment which are VESA-compatible. There are also stands and ceiling hanging facilities available that can be used to install the screen.
How is a player PC connected to the network?
Normally, a player PC will be connected to the local network, or at least to the Internet, in order to allow updating and managing the screen content remotely. Also live data such as weather conditions or RSS newsfeeds will require an Internet connection. Apart from common, cable-based networking technologies such as Ethernet, wireless LAN can also be used to connect the player PC with the network. A third option is to use a proprietary technology such as PowerLAN which uses the existing power line infrastructure of a building to also transmit data over it.
If there is absolutely no way for you to connect the player PC to a local network or the Internet you can also use a USB flash drive to update the player PC using FrontFace. In this case you should make sure that a USB connector of the player PC is easily accessible so you can plug in the USB flash drive while FrontFace software is running. You can use a USB extender cable to “relocate” a USB plug to a location where you can easily reach it (without having to fumble in the gap between wall and screen).
Is it also possible to update the player PC over the Internet?
Of course. Apart from updating the player PC using a local network (LAN or wireless LAN) or a USB flash drive (offline), you can also update the player PC over the Internet using FrontFace. You can either set up a VPN connection between your site and the site where the player PC is, or you can use a Cloud storage service (such as Dropbox or OneDrive) to replicate the content from your PC over the Internet to the player PC. In such a scenario is does not matter where in the world your PC is located and where the player PC is – as long as both PCs have access to the Internet, they can communicate with each other over the Cloud.
