DEVICES

Start Here

The foundations: what a device is, the Devices Window, and how to add and configure displays.

• Devices Overview - the three device types, what they share, and how they appear in cues
• Adding Displays - 2D Display vs 3D Projector positioning and the five output device types
• Display Properties - the complete reference for all display property groups
• Display Grid Setup - rapidly configuring uniform tiled arrays (LED walls, monitor matrices, projection grids)
• 3D Projector - positioning a pixel output as a 3D camera with Eye/Target/Roll and lens parameters

Video Devices

The five output devices a display can be routed to. Each page covers what is specific to that routing.

• GPU Output - render to a physical GPU connector on a node. Default for new displays.
• SDI Output - baseband video over coaxial cabling through a Deltacast SDI board.
• ST 2110 Output - uncompressed video over IP through a Deltacast ST 2110 board, with PTP-synchronized timing.
• NDI Output - network video stream over standard Ethernet, discoverable by any NDI receiver.
• Virtual Output - an internal texture buffer with no physical output, usable as a media source elsewhere in the show.

Audio Devices

Driver types for audio output. WATCHOUT runs on Windows; the driver chosen here determines how WATCHOUT talks to the sound hardware.

• Audio Devices - the audio device model: drivers, channels, format, latency, and the bus routing matrix.
• WASAPI - Windows shared audio, the default for integrated and consumer audio devices.
• WASAPI Exclusive - exclusive-mode access for lower latency; other applications lose access to the device.
• ASIO - professional audio interface driver model with the lowest latency.
• Dante Audio - networked professional audio routing to any Dante receiver on the network.

Capture Devices

Bring live video and audio streams into the show. Each capture device holds one or more sources, distributed across the nodes that need to render the capture.

• Capture Devices - the capture device model: sources, cues, and how captures play across nodes.
• Generic Capture - Windows-recognized capture hardware: webcams, USB capture cards, HDMI capture sticks.
• NDI - receive NDI® streams from cameras, switchers, and other NDI-enabled sources on the network.
• Deltacast VideoMaster - professional broadcast capture over SDI, HDMI, or ST 2110 through a Deltacast board.
• Spout - shared-GPU-texture capture from another application on the same node.

Geometry Correction and Blending

Tools for shaping output to fit real-world surfaces and multi-projector overlaps.

• Edge Blending - complementary intensity gradients across projector overlap zones for seamless multi-projector images
• Warp Geometry - mesh-based geometry correction for curved screens, angled projectors, non-rectangular targets, and domes
• Display Masks - alpha-based mask overlays for hiding regions of rendered output, controlling light spill, and shaping non-rectangular boundaries
• MPCDI - VESA Multiple Projector Common Data Interchange — externally calibrated subpixel warp, per-channel alpha blend, and beta-mask black-level lift

Color, Calibration, and Diagnostics

Fine-tuning output quality and verifying display setup.

• Color Pipeline - how a pixel travels from source decode, through linear wide-gamut compositing, to display output
• HDR and Color Management - per-display color space, transfer function, bit depth, white point, and SDR/HDR output
• Display Calibration - NDI calibration streams, projector calibration via 3D point correspondences, EDID management, and external API integration
• Test Patterns - five built-in diagnostic modes and the Render Info overlay for verifying signal routing and alignment
