NovaStar ET series media servers for LED and LCD displays
Choose the NovaStar ET1S, ET1S-500, ET2S, ET4S(P2), ET4S(A4), ET16S(2A4) or ET16S(3A4) according to the required output resolution, simultaneous media layers and synchronization features. The configurations differ, so the selected model determines the hardware and playback capability supplied.
ET series model comparison
The table transcribes the output, chassis, software and layer specifications from the original comparison chart retained below. Confirm the selected configuration before ordering.
| Model | Chassis | Listed load capacity | Playback software | Layers |
|---|---|---|---|---|
| ET1S | 1U | 1 × 4096 × 2160 at 60 Hz | Kompass FX1 | 4 layers + 1 audio layer |
| ET1S-500 | 1U | 1 × 4096 × 2160 at 60 Hz | Kompass FX1 | 4 layers + 1 audio layer |
| ET2S | 2U | 2 × 4096 × 2160 at 60 Hz | Kompass FX2 | 8 layers + 1 audio layer |
| ET4S(P2) | 4U | 4 × 4096 × 2160 at 60 Hz | Kompass FX3 | 12 layers + 1 audio layer; expandable |
| ET4S(A4) | 4U | 4 × 4096 × 2160 at 60 Hz | Kompass FX3 | 12 layers + 1 audio layer; expandable |
| ET16S(2A4) | 4U | 8 × 4096 × 2160 at 60 Hz | Kompass FX3 | 24 layers + 1 audio layer; expandable |
| ET16S(3A4) | 4U | 12 × 4096 × 2160 at 60 Hz | Kompass FX3 | 36 layers + 1 audio layer; expandable |
Output capacity and decoding capability describe different limits. For example, the chart recommends 1 × 4K2K at 60 fps or 4 × 2K1K at 60 fps for ET1S and ET1S-500, while ET4S(P2) lists 1 × 8K4K at 30 fps or 3 × 4K2K at 60 fps. Check the intended media files and layer arrangement as well as the screen output.
ET1S connections and playback
The linked ET1S specification V1.0.0, dated July 26, 2024, describes one 4K × 2K output at 60 Hz, up to four playback layers and one audio layer. Its output connections are one DP 1.2, four HDMI 1.3 connectors that together copy the DP output content, and one HDMI 2.0 connector that copies the DP output content. These connectors do not establish six independent 4K outputs.
ET1S supports up to 1024 partitions of a single output for mapping and ultra-wide-screen layouts. Kompass FX1 provides media-library management, batch import, program arrangement, crossfade switching, layer masking and cropping, and one-click fade-to-black. Supported media include video, images, audio, PowerPoint, NDI, website, streaming and text sources. The document specifies PowerPoint support up to 1080p.

Storage, backup and synchronization choices
The comparison chart lists a 250 GB M.2 SSD for ET1S and a 500 GB M.2 SSD for ET1S-500. Both are 1U models with Kompass FX1 and the same listed output and layer capacity.
Dual-machine hot backup is not listed for ET1S, ET1S-500, ET2S or ET4S(P2). It is listed for ET4S(A4) with an additional sync card, and for ET16S(2A4) and ET16S(3A4). Multi-machine cascading and frame synchronization are separate functions: the chart lists frame synchronization for ET4S(A4) and the two ET16S configurations, but not for the other four configurations.
Before selecting a server, prepare the screen canvas dimensions, required output connections, video resolutions and frame rates, number of simultaneous layers, storage needs and backup requirements. Confirm optional cards and any layer expansion for the exact configuration.

NovaStar ET media server FAQ
What is the difference between ET1S and ET1S-500?
The original chart lists a 250 GB M.2 SSD for ET1S and a 500 GB M.2 SSD for ET1S-500. Both list a 1U chassis, Kompass FX1, one 4096 × 2160 output at 60 Hz, and four layers plus one audio layer.
Are all ET1S HDMI and DP connectors independent outputs?
No. The ET1S PDF says the four HDMI 1.3 connectors together copy the DP 1.2 output content, and HDMI 2.0 also copies that content. Plan the layout around the documented output capacity.
Which ET models support dual-machine hot backup?
The chart lists ET4S(A4) with an additional sync card, ET16S(2A4) and ET16S(3A4). It marks ET1S, ET1S-500, ET2S and ET4S(P2) as not supported.
How many media layers does each model support?
The listed capacities are four for ET1S and ET1S-500, eight for ET2S, twelve for either ET4S configuration, twenty-four for ET16S(2A4), and thirty-six for ET16S(3A4). Each also lists one audio layer. ET4S and ET16S layer expansion is configuration-dependent and should be confirmed before purchase.
Does the ET1S specification PDF cover every ET model?
No. The download is the ET1S specification. Use the comparison chart for the listed differences across the range, and confirm the detailed connections and supplied hardware for any other selected model.
