One CMS may suit you. Being unable to leave it is the cost

Most digital signage estates are bought as a package: panels, players and a content platform from one place. That is tidy until the software side stops suiting the job. If the hardware is tied to the platform, a change of CMS becomes a change of screens, and the cost lands on whoever specified the estate.

IDS builds its hardware against that problem. The Lumina reflective and e-paper range, RC Stars and IDS LCD are multi-CMS compatible, with open, modular integrations. The aim is that the content platform can be revisited without the displays being the obstacle. That describes inputs and compatibility, not approval by any particular software vendor, so a specific hardware and CMS pairing should always be confirmed before it is specified. IDS can also manage more than one platform on a client's behalf, so open integration does not become extra work for the client.

The trade press offers no example of a vendor collapsing and leaving screens dark, and we do not imply one. The risk is structural, and the reporting below describes the conditions that make it expensive.

The objection, answered first

The fair objection is that one vendor, one platform and one point of contact is simpler, and open integration just means more to manage. There is something in that. Darryl Kuder, CEO of Red Dot Digital Media, argues in a Digital Signage Today commentary that putting every screen on one CMS is often the wrong default, yet he concedes that a single CMS is sometimes right, provided the choice is deliberate. The argument is about the default, not the exception.

A client can still choose one platform. The difference is whether that choice can be reversed. Standardising on a closed stack gives simplicity until it stops doing so, and the exit cost is then the whole estate. On open hardware, simplicity is a choice and the exit is not blocked.

Kuder's reasoning is practical. An interactive wayfinder built on custom HTML needs different things from corporate communications going to many screens, and a broad platform means paying for functions that go unused. He also runs an integrator with its own best-of-breed approach, so read his piece as a view from one side of the argument, not as reporting.

Why the software layer is the part that moves

Commercial pressure on that layer is rising. WARC Media's Q3 2026 forecast, issued as a press release and so WARC's own projection, has retail media growing 14.3% to $202.1bn in 2026 and digital out-of-home growing 13.7% to $21.7bn, with growth expected to moderate in 2027. A Digital Signage Pulse listing says 7-Eleven Australia has launched a retail media network that includes in-store screens; we have seen only that summary, not the original report. Screens that began as menu boards or notices can be asked to carry paid content, which may call for a different platform from the one they started with.

A study relayed by Pulse suggests why that move is not trivial. Pulse summarises an Invidis report on an IAB study: inventory and scale ranked among the top three considerations for 59% of respondents weighing in-store digital media investment, and measurement limits and campaign-activation complexity remain obstacles. We have read the summary, not the study. Our reading is that these are software and operations problems. A retailer whose platform cannot meet them needs to change the platform. It should not also need to change the screens.

Digital Signage Today's report on the Dignity Health Arena in Bakersfield shows how many parties can touch one sign. The new freestanding LED pylon was supplied by SNA Displays, designed and administered by Anthony James Partners, and installed by Sign Factory. The article says the sign is meant to serve visitors and earn advertising revenue for the city. The project says nothing about changing platforms; it simply shows a dual-purpose sign with several suppliers behind it. If the hardware is specified independently of the content layer, a change in the revenue model touches the content relationship rather than the pylon.

What open hardware does not do

Open hardware does not solve measurement, scale or buying complexity. Those sit with the software and the media operator. What the hardware can do is stop them being reasons to replace the screens.

A question to put to clients

For resellers and integrators, this changes the conversation. Instead of selling a package and inheriting its risks, specify the display layer once and treat the software as a decision that can be revisited. For a client who later wants retail-media content on screens installed as wayfinding, the question becomes which platform to move to, not whether to remove what is on the wall.

Ask: "If your content platform had to change, which parts of this estate would you have to replace?" If the answer includes the displays, that is the risk to price in. A lock-in check on an estate, set against Lumina, RC Stars and IDS LCD, is a sensible place to start. Where a client already has screens that may one day carry paid content, the question carries more weight.
