# Which screens work, and what you need to run them > A screen, something to play the content, power and internet. Here's what to look for in each, what to check before buying, and which systems the Jonza player runs on. Guides · https://jonza.app/en/guides/which-screens-work · [TR](https://jonza.app/tr/rehberler/hangi-ekranlar-calisir.md) ## The four parts of a signage screen Every signage setup, however large, comes down to the same four things. Getting each one right matters more than the brand on the front of the screen. - The display: the panel people look at. A TV or a professional display. - The player: the computer that runs the signage software. It can be built into the screen, or a small box plugged into it. - Power and internet: a socket close by, and a connection the player can use to receive changes. - The mount: what holds the screen where people will see it. Many modern TVs and displays include a player, because they run an operating system that apps can be installed on. Others are just a panel, and need a separate player connected by HDMI. Both work. What matters is that the player runs a system your signage software supports. ## Which systems the Jonza player runs on The Jonza player runs on these systems: - Linux - Windows - Android - Google TV - Amazon Fire TV - LG webOS - Raspberry Pi - Samsung Tizen In practice this covers a lot of ground. Screens with LG webOS or Samsung Tizen built in can run the player directly. Android covers many screens and small media boxes, and Google TV and Amazon Fire TV sticks turn any TV with an HDMI port into a signage screen. A Raspberry Pi, a Linux machine or a Windows PC can sit behind a screen that has no system of its own, connected by HDMI. If your screen or player runs something else, or you're not sure what it runs, ask us before you buy anything. If you already have screens, our team can connect to them remotely and set them up for you; if you'd rather start fresh, we can ship Tochi screens, Erpa's own brand made in Türkiye, with Jonza already set up. > To find out what a TV runs, look up its model number on the manufacturer's site, or open its settings: the system name is usually under "About" or "Software information". ## Commercial displays or ordinary TVs? Professional, or commercial, displays are built to be on all day. They tend to be brighter, often allow portrait mounting, and come with warranties that expect long daily use. They also cost more, sometimes a lot more, than a TV of the same size. Ordinary consumer TVs are cheaper and easy to find, and many businesses run them happily for years. The trade-offs are worth knowing, though. Their warranty may not cover commercial use or long hours each day, some aren't meant to be mounted in portrait, and they may be less bright in a sunny spot. Some also show their own pop-ups or go to sleep on their own, which you'll want to switch off in the settings. There's no single right answer. As a rough guide: - A screen inside, away from sunlight, on for shop hours: a good consumer TV is often fine. - A screen in a shop window, in direct sun, or on almost all day: a commercial display is usually worth the price. - A portrait screen: check that the model supports it, and that the warranty still applies when it's mounted that way. Whichever you choose, read the warranty terms for commercial use before you buy. They vary by manufacturer and by model. ## Internet Signage software that you manage remotely needs each player to be online, to receive changes and report how it's doing. A wired Ethernet connection is the most reliable option when you can run a cable to the screen. Wi-Fi works too, but check the signal at the exact spot the screen will hang, not at the counter. - Put the player on a network that stays up when the shop's other devices are busy. - If you use Wi-Fi, avoid spots behind metal shelving, fridges or thick walls. - Write down the network name and password before the installer arrives. Jonza shows each screen's status and signal history in the dashboard, so a weak connection is easy to spot after the screen goes up. ## Mounting and placement Most screens use a standard mounting pattern on the back, so wall and ceiling brackets fit many models. Check the pattern and the screen's weight against the bracket's limits, and make sure the wall can take it. - Plan the cables: power, and network if wired. Hidden cables look better and are harder to pull out. - Leave room behind the screen for a separate player, if you use one, and for air to flow around it. - Avoid spots right above heaters, ovens or coffee machines. - If staff need to reach the screen, leave enough clearance to get a hand to its buttons or ports. ## From box to screen with Jonza 1. **Turn the screen on**: Turn on a screen with Jonza installed and connect it to the internet. 2. **Pair it**: The screen shows a six-digit code. Type it into the dashboard and the screen is yours. 3. **Publish**: Choose what it plays from a laptop or a phone. The screen picks it up within seconds. ## What to ask before you buy A few questions save most of the trouble: - Which operating system does this screen or player run, and is it one my signage software supports? - Is it covered by warranty for commercial use, and for the hours I'll have it on? - Can it be mounted in portrait, if I need that? - Is it bright enough for where it's going: inside, near a window, or in the window? - Will it turn itself off, show pop-ups or ask for updates on screen, and can those be switched off? - Is there power and a good connection at the spot where it will hang? If you're planning screens for Jonza and aren't sure about a model, send us the details before you order. It's quicker than returning a screen. ## Questions ### Do I need to buy special equipment for Jonza? No. We can ship Tochi screens with Jonza already set up, or if you already have your own, our team connects to them remotely and sets everything up. The player runs on Linux, Windows, Android, Google TV, Amazon Fire TV, LG webOS, Raspberry Pi and Samsung Tizen. ### My TV isn't a smart TV. Can I still use it? Usually, by connecting a separate player to it over HDMI: for example a Fire TV Stick, a Google TV or Android box, a Raspberry Pi, or a small Linux or Windows PC. Ask us if you're unsure which to choose. ### Can I rotate a screen to portrait? Jonza supports landscape and portrait screens, and you can set a screen's rotation remotely. Check that your screen's maker allows portrait mounting first. ### What if my platform isn't on the list? Ask us. Write to us with the model and what it runs, and we'll tell you what's possible. ## Read next - [Device Management](https://jonza.app/en/features/device-management.md): Live status for every screen, tags for branches and floors, and remote settings without a site visit. - [USB Stick vs Jonza](https://jonza.app/en/compare/usb-stick-vs-jonza.md): What changes when your screens update from one place, instead of a stick carried to each TV. - [Setting Up a Café Menu Board](https://jonza.app/en/guides/cafe-menu-screen-setup.md): Placement, orientation, text size, how many items, photos and prices: a menu screen that people can actually read. --- Jonza is a digital signage platform by Erpa Teknoloji.
