Run several screens from one PC or Mac

Quick answer: DigitalSignage.com SignPlayer Desktop on Windows or Mac drives as many screens as the computer has video outputs: set the operating system to extend the displays rather than mirror them, then assign each output its own screen in SignStudio, so a mini PC with two or three HDMI or DisplayPort outputs runs a row of menu boards or a small video wall from one installation. Pricing is per screen: the first 3 are free forever, then $3 per screen per month once an account has 4 or more. For identical content everywhere, an HDMI splitter is simpler; beyond three or four outputs, one inexpensive player per screen is usually cheaper.

Three ways to feed several screens

Setup	How it works	Content	Cost per extra screen	Best for
One SignPlayer Desktop, several outputs	Extended desktop; each output is a screen in SignStudio	Different content per output, or one layout spanning the wall	Nothing in hardware if the outputs exist; the screen is billed from the fourth	Menu-board rows, a 2 by 1 or 2 by 2 wall, Mac shops
One output and an HDMI splitter	The signal is duplicated to several panels	Identical on every panel	A splitter and cables; one screen in SignStudio	Repeating the same loop down a corridor or across a counter
One player per screen	Each screen has its own $30 to $100 player	Fully independent	A stick or a Raspberry Pi plus the screen's billing	Screens in different rooms, mixed orientations, anything over four outputs

Set up several outputs on Windows

1. Install SignPlayer Desktop from the Downloads page in your account and pair the first screen: type the registration code shown on the player into SignStudio under Register SignPlayer.
2. Connect each screen to its own output. Mini PCs and NUC-class machines often have two or three HDMI or DisplayPort outputs; a dedicated GPU adds more. Check the outputs before you buy the PC.
3. In Windows display settings, set the displays to extend, not duplicate. Set each display to its native resolution and the right orientation.
4. Assign each output its own screen in SignStudio and give each a clear name, for example Menu Left, Menu Center, Menu Right. The Windows install guide notes that a second screen showing the same content means the displays are duplicated; switch to extend and assign each output its own screen.
5. Publish a campaign per screen, or one wide layout for a wall, and check all outputs after a reboot.

For a 2 by 2 wall on professional GPUs, the Windows platform guide documents NVIDIA Mosaic and AMD Eyefinity, which join several outputs into one large desktop with bezel correction, so a single 3840 by 2160 scene spans four Full HD panels.

Set up several outputs on a Mac

1. Install SignPlayer Desktop for Mac from the Downloads page and pair the first screen with the registration code.
2. Connect each display to its own output. A Mac mini with two display outputs runs two menu boards or a two-screen wall from one installation.
3. In the Displays settings, set the displays to extend rather than mirror, and set each to its resolution and rotation.
4. Assign each output its own screen in SignStudio and publish.
5. Make the Mac unattended as the Mac setup guide describes: a dedicated user with automatic login, SignPlayer in Login Items, sleep and screen saver off, and start up automatically after a power failure. Then pull the plug once and watch every screen come back.

Hardware limits to plan for

Screens from one computer	Minimum build	Notes
2 at 1080p	Core i3 or Ryzen 3 class, 4 GB RAM, SSD; any Mac on a supported macOS	Most mini PCs and a Mac mini qualify
2 to 3 with 4K video or many zones	Core i5 or Ryzen 5, 8 GB RAM, 128 GB SSD; Mac mini	The recommended Windows build on the install guide
4 panels as a video wall	Core i7 or Xeon class, 32 GB RAM, professional GPU, 1 TB storage	The Windows platform guide's video wall specification
More than 4	Not from one desktop player	Use a wall controller, or one player per screen

Each extra screen multiplies the decoding load: three 1080p videos at once need roughly three times the GPU and memory of one. Cable length matters too; HDMI runs over about 15 meters need active cables or extenders, which often argues for a player at each screen instead of long cables back to one PC. A Raspberry Pi 4 or 5 has two micro-HDMI outputs and drives two displays, and many Chromeboxes have HDMI plus DisplayPort, so the small players also cover a pair.

When one player per screen wins

• The screens are in different rooms or on different floors.
• Screens have different orientations or resolutions, for example a portrait directory beside a landscape welcome screen.
• A single failure must not take down a whole row. One player per screen fails one screen at a time.
• You want to add screens later without rebuilding the PC.
• The budget is tight: a $30 to $60 Android TV stick or a Raspberry Pi under $100 per screen is cheaper than a GPU upgrade, and the first 3 screens cost nothing in software.

The players and hardware FAQ sums it up: for the same content on several screens a splitter works with one player, and for different content on each screen one inexpensive player per screen is usually simpler and more reliable.

Billing

DigitalSignage.com bills per screen registered in SignStudio, however it is fed. Two outputs from one PC are two screens; one output into a splitter feeding four panels is one screen. The first 3 screens are free forever; once an account has 4 or more screens every screen is billed from $3 per screen per month on Plus+, and Enterprise is priced per screen in the public price calculator.

Frequently asked questions

Can one PC run several digital signage screens?

Yes. SignPlayer Desktop on Windows supports as many screens as the PC has video outputs. Set Windows to extend the displays, assign each output its own screen in SignStudio and publish a campaign to each. A mini PC with two or three HDMI or DisplayPort outputs runs a row of menu boards or a small video wall.

How many displays can a Mac mini drive for digital signage?

SignPlayer Desktop for Mac drives as many screens as the Mac has video outputs; a Mac mini with two display outputs runs two menu boards or a two-screen wall from one installation. Set the displays to extend rather than mirror, and assign each output its own screen in SignStudio.

Do I need extended or mirrored displays?

Extended, for different content on each screen; each output then becomes its own screen in SignStudio. Mirrored or duplicated displays show the same picture everywhere and only count as one screen, which an HDMI splitter also achieves from a single output.

Can I make a video wall from one PC?

Yes, for small walls. A 2 by 2 wall uses four outputs joined into one desktop with NVIDIA Mosaic or AMD Eyefinity on a professional GPU, as the Windows platform guide documents, and one large scene spans all four panels. Larger walls use a wall controller or one player per panel.

Is it cheaper to use one PC or one player per screen?

For two or three screens in one place, one PC with enough outputs is cheap. Beyond that, or for screens in different rooms, a $30 to $60 Android TV stick or a Raspberry Pi per screen costs less than a GPU upgrade and long cable runs, and a fault affects one screen instead of all of them.

How does DigitalSignage.com bill several screens from one computer?

Per screen registered in SignStudio. Two outputs from one PC are two screens; one output into a splitter is one screen. The first 3 screens are free forever, and once an account has 4 or more every screen is billed from $3 per screen per month on Plus+.
