NovaStar VS1 video processor for LED display systems
The NovaStar VS1 is a video processor with HDMI, DVI, VGA and composite-video inputs, two DVI outputs and adjustable picture-in-picture. It processes and scales the video signal for an LED display system; the downstream sending-card and receiving-card configuration must be checked separately.
This page follows NovaStar’s Chinese-language VS1 Video Processor Specifications V1.2.4, with selected connection information from the matching user manual. Use the exact VS1 model and installed hardware when planning a system or replacing an older processor.

The V1.2.4 overview describes a 1920 × 1200 maximum output, while its detailed output table also lists 2048 × 1152 at 60 Hz and custom resolutions. Verify the exact timing against the installed firmware and downstream equipment. Do not combine separate width and height values into an undocumented output format.
Check the video path and installed sending hardware
The rear panel separates DVI video outputs from the USB CTRL and UART connections. Its chassis has positions for sending cards; the manual describes installation of two cards. That does not establish which cards, if any, are supplied with a particular unit. Confirm the installed models, signal cables and receiving-card configuration before using a pixel-capacity figure.
UART IN/OUT is labeled as reserved in the specification. These RJ45-shaped connectors must not be mistaken for LED data outputs or an ordinary network-control connection. Confirm any required multi-unit control behavior for the actual hardware and software.

PIP source pairs and presentation controls
The VS1 allows adjustment of PIP size and position, but not every pair of inputs can operate simultaneously as the main and PIP pictures. The V1.2.4 conflict table excludes HDMI together with DVI, and AV1 together with AV2. For example, two composite-video devices connected to AV1 and AV2 cannot provide an independent main/PIP pair under that table.
Fade transitions, image cropping, freeze and front-panel source selection provide presentation controls. Plan the two source types and output timing first, then check the intended PIP layout. Scaling or cropping does not remove an input-pair restriction or increase the downstream LED system’s capacity.
NovaStar VS1 selection questions
Does 12-bit internal processing mean every input accepts 12-bit video?
No. The specification describes internal 12-bit digital processing separately from its 10-bit/8-bit video-input feature. Confirm the source format and connector requirements rather than treating internal processing depth as an input-format guarantee.
Can the USB CTRL port play videos from a USB drive?
V1.2.4 identifies CTRL as a computer-control interface. It does not document USB-drive media playback. Plan a compatible external video source when local content playback is required.
Are the linked VS1 specification and manual in English?
The original V1.2.4 downloads linked on this page are in Chinese. Their language does not change the model or revision. Contact EagerLED if you need help identifying the correct connection, timing or configuration section.
What information is needed for a VS1 configuration review?
Provide the complete model label, source connectors and timing, required main/PIP pair, target output timing, sending-card models and receiving-card setup. Include the screen pixel dimensions and cabinet map so the complete signal path can be assessed.
