• Graphics & Video:
• GPU: VideoCore VII with OpenGL ES 3.1 and Vulkan 1.2 support
• VPU: Capable of 4Kp60 HEVC decoding, perfect for smooth video streaming
• Memory & Storage Options:
• RX540: 4GB RAM, 16GB eMMC flash storage
• RX580 variant: 8GB RAM with the option for internal storage expansion
• Connectivity & I/O:
• Dual HDMI outputs supporting up to 4K @ 30 Hz
• A full suite of USB ports (2× USB 3.0 and 2× USB 2.0)
• Dual-band WiFi (802.11b/g/n/ac), Gigabit Ethernet, and Bluetooth 5.0
• Additional Features:
• A dedicated power button and LED indicator
• Kensington lock slot for physical security
• Powered via a 5V DC USB-C connector

This robust hardware configuration ensures that the RX540 is more than capable of managing even resource-intensive remote desktop sessions. By integrating a modern ARM processor with high-quality graphics and connectivity options, NComputing capitalizes on the strengths of the Raspberry Pi ecosystem while catering to the growing demand for efficient thin clients.

Lightweight Yet Feature-Rich Operating System​

The RX540 runs on NComputing’s proprietary LEAF OS—a streamlined Linux distribution optimized for remote computing experiences. Key aspects of LEAF OS include:

• Enhanced Virtual Desktop Experience:
  LEAF OS integrates NComputing’s vCAST Streaming technology, which minimizes server-side CPU load during video playback. Whether you’re streaming YouTube videos or opening multimedia files, the device delivers a smooth and responsive experience.
• Local Application Support:
  Pre-installed applications such as the Chromium Browser, Microsoft Teams Progressive Web App (PWA), Zoom, and other third-party Linux software ensure that users have essential tools at their fingertips. Additionally, users can extend functionality via a custom module support system.
• Easy Onboarding and Management:
  The OS is paired with PMC Endpoint Manager software, which simplifies device onboarding and provides real-time administrative oversight—a vital feature for IT departments managing numerous terminals.

For early adopters and IT administrators curious about the platform’s potential, NComputing offers a 30-day trial of LEAF OS on existing hardware. This low-risk testing phase allows companies to evaluate system performance and integration into their virtual desktop infrastructures.

Seamless Integration with Windows Virtualization Ecosystems​

One of the strongest selling points of the RX540 thin client is its compatibility with an array of virtualization protocols and platforms that many enterprises rely on today. In particular, the device supports:

• Microsoft Azure Virtual Desktop (AVD) and Windows 365:
  The ability to access Windows desktops via cloud services makes the RX540 an ideal candidate for organizations adopting a hybrid or fully remote work model. Enterprises can create secure, manageable desktop environments that leverage the scalability and flexibility of Microsoft’s cloud solutions.
• Traditional Remote Desktop Services (RDS):
  For environments still reliant on on-premises server infrastructures, the RX540 offers a reliable and cost-effective solution.
• Citrix HDX and Beyond:
  With dedicated support for Citrix protocols, the device ensures that users experience smooth transitions and operational consistency in Citrix-powered environments.

This level of ecosystem flexibility means companies can preserve existing investments in remote desktop technology while exploring cloud-driven alternatives. The upcoming Omnissa Horizon integration (expected in March 2025) further expands the device’s connectivity and remote management features.
The trend toward leaner, cloud-managed endpoints isn’t new. As discussed in our previous coverage of Windows 10 support transitions (as previously reported at https://windowsforum.com/threads/353937), the evolution of remote desktop solutions reflects the broader industry movement toward streamlined, cost-effective endpoint computing.
