Kards 1.3.1 by Alteka Solutions is a cross-platform test card generator engineered for audiovisual professionals who need to verify signal paths, calibrate displays, or demonstrate system capabilities. The application outputs a comprehensive set of industry-standard test patterns—including color bars, grayscale ramps, PLUGE, convergence grids, and motion rectangles—that can be sent to any monitor, projector, or capture device connected to a Windows, macOS, or Linux workstation. Users select the desired pattern, choose resolution and refresh rate from a drop-down that covers common broadcast and computer formats up to 4K, and push the signal through HDMI, SDI, DisplayPort, or NDI with frame-accurate timing; a built-in audio tone generator can accompany the video to test embedded audio channels. Typical scenarios include lining up multi-screen video walls, confirming HDR metadata, stress-testing switchers, or providing a reference source during live-event rehearsals. Because the program is portable and GPU-accelerated, technicians can carry it on a laptop and generate reliable test cards on location without extra hardware. The single-version release history indicates that 1.3.1 is the first public build, yet it already offers preset management, hot-key switching, and safe-area overlays, making it suitable for broadcast engineers, AV installers, rental technicians, and content creators who require a lightweight but professional signal source. The utility falls under the Video Tools / Test & Measurement category and is compatible with Windows 10 or later, macOS 11+, and mainstream Linux distributions. Kards is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, ensuring the latest build is always provided and enabling batch installation alongside other applications.
