Below are the most frequently asked questions. If you don’t find an answer here, contact us and ask your own.


How long does the calibration take?
Scalable calibrations take roughly 30 seconds per projector. A ten projector system would take about 5 minutes to align, a two projector system can be recalibrated in under a minute. Initial configuration time is the longest part of setup since it requires user to input screen information and optimize variables for fast and successful recalibrations.
How accurate is Scalable's camera-based calibration?
Scalable is the world leader in camera-based calibration of projectors. Our patented algorithms allow for edge-blending that is registered on a sub-pixel level and our geometric warping has subdegree accuracy as measured with a theodolite.
What Scalable product do I need?
Which product to use is largely based on your application requirements and pixel pipeline, if you’re running primarily Windows applications such as, PowerPoint, Excel, AutoCAD, Video Conferencing etc. with a limited number of external inputs, ScalableDesktop is likely the best product for you. ScalableDesktop warps the Windows OS, so all content must originate on or pass through the ScalablePC or Machine running ScalableDesktop (non-HDCP compliant). If you are setting up a simulator, or a display system driven by a cluster of PCs or a Media Server, then Scalable Display Manager or Scalable Panel Assembly is a better fit. These products are capable of perspective warps for simulators and support multiple ways to apply the warp & blend which are not limited to a single machine for playback. You can learn more about each product here or by contacting the Scalable sales team.
My media servers and projectors have built-in edge-blending, do I still need Scalable?
While many new projectors and media servers have built-in tools for edge-blending, it’s important to remember that Scalable’s unique value proposition is the camera. Manual edge-blending can take days or weeks to perfect, and requires a skilled projectionist to setup. With Scalable the camera does all the hard work for you. Additionally the camera ensures that the display is always pixel-perfect, reducing the cost of system maintenance over the lifetime of the display, and guaranteeing that the system is always ready for use. So while your display design may be technically achievable with tools available in a projector or in a media server, Scalable can still be added to the system to automate the setup and maintenance process, saving you valuable time and money.
Do I need special projectors with edge-blending feature to use Scalable Software or will any projectors work?
You don’t need special projectors to use Scalable software, any make or model of projectors will work.
Does Scalable software work with any graphics cards?
ScalableDesktop is compatible with Nvidia Quadro cards (see the full list here).

Scalable Display Manager (SDM) is set up in Host & Client architecture. The Host running SDM does not require a specific graphics card. The Clients may use Nvidia Quadro cards to apply the warp & blend, but for SDK applications or hardware integrations the graphics card on the client machines are not specific to Scalable.

Does Scalable software work with any camera?
No, you need a Scalable supported camera. There’s a growing list of supported cameras, from DSLR to small factor GigE cameras and webcams. See the full list here. If there is a specific camera you would like Scalable to support in the future contact us.
How many cameras will I need?
Fewer cameras is always faster and easier to set up, technically only 1 camera is required if it can see all projected pixels without obstructions. For complex geometry screens and installations with limited throw distance, we simply add cameras until the entire screen is visible. Scalable provides camera-modeling services to assist with determining the right camera layout and best camera/lens option for the project.
What file format do you support for camera modeling?
For 3D camera placement we support DWG or DXF file formats. We can also ROM camera quantity and approximate location based on a PDF of a 2D plan model, but 3D models in DWG or DXF are preferred.
Which IGs are SDK integrated with Scalable software?
The majority of SDK integrated applications can be found here.
Does Scalable support 3D applications?
Yes, Scalable supports both active and passive stereoscopic 3D.
Does Scalable support stacking projectors for brightness?
Yes, Scalable supports both tiled (blended) and stacked displays. Scalable also supports a combination of stacking and tiling for increased resolution and increased brightness.
Can I really drive 16 projectors from 1 PC with ScalableDesktop?
Yes. Nvidia’s SYNC & SLI technology allows you to combine up-to 4 graphics cards in a single PC. Each Quadro card is capable of 4 DisplayPort outputs, and 4 projectors per card = 16 projectors! It is important to note that Windows has a limitation of 16,000 pixels in any single direction (X or Y).

If your project requires a canvas beyond 16k pixels, you can use Scalable Display Manager (SDM) with a distributed render cluster of PCs or a Media Server designed for high resolution playback.

If I have the Scalable SDK, do I still need Scalable Display Manager?
Yes, absolutely, the SDK enables an application to read and render the Scalable Mesh Files. A license for Scalable Display Manager (or Scalable Panel Assembly) is still required to create the Scalable Mesh File. SDM or SPA can be thought of as the warp and blend generators, the SDK allows an application to use the calibration files with full flexibility on hardware and system OS.
