18G 4K HDR HDMI ProScale Digital Scaler with HDMI, USB-C and VGA Inputs

The VP-426C is a high-performance digital scaler built to accept HDMI, USB Type-C and VGA computer-graphics signals through a single, clearly defined signal path. After the user selects an input, the unit upscales or downscales that source and sends the processed result to its HDMI output. Its headline capability is output scaling to resolutions up to 4K@60 with 4:4:4 color, backed by an 18Gbps maximum data rate and HDR10 support. This combination gives mixed-format video systems a direct way to standardize output resolution while retaining high-bandwidth 4K performance.

Ideal Use Cases

The VP-426C is suited to systems that must accommodate HDMI, USB-C and VGA sources without assigning a separate scaler to each signal format. One installation can accept a digital HDMI feed, a USB Type-C feed or a VGA computer-graphics feed, then deliver the selected and scaled signal to an HDMI destination. Its up- and down-scaling capability is useful whenever the source resolution and required output resolution do not match. It also supports workflows in which an operator needs a straightforward choice among three source-interface types while maintaining one consistent HDMI output connection.

Why Choose This Model

The VP-426C concentrates on two essential functions: source selection and resolution conversion. Rather than limiting the system to one input family, it places HDMI, USB Type-C and VGA inputs on the same scaler. It can therefore address mixed-source requirements while presenting the downstream HDMI device with a scaled HDMI signal. The 18Gbps bandwidth supports the stated maximum output of 4K@60 with 4:4:4 color sampling, while HDR10 support provides compatibility with HDR10 signals. The published maximum data rate is 6Gbps per graphic channel, totaling 18Gbps. These stated limits provide concrete guidance when comparing resolution, color sampling, bandwidth and HDR capabilities.

Installation and Integration

Integration follows a direct signal topology. Connect the required sources to the HDMI, USB Type-C and VGA inputs, connect the scaler’s HDMI output to the target HDMI device, and select the source that needs to be processed. The same HDMI output path handles both upscaling and downscaling, allowing system design to center on the required output resolution instead of requiring every connected source to begin at that resolution. Because the downstream connection remains HDMI, changing between the available input formats does not change the stated output interface. The source data does not specify dimensions, mounting options, power requirements or environmental limits, so those details should be confirmed separately when planning a complete installation.

Performance Highlights

The primary performance feature is scaling to resolutions up to 4K@60 with 4:4:4 color. This maximum operates within an 18Gbps data-rate ceiling, divided as 6Gbps per graphic channel. The VP-426C can scale in either direction, enabling it to raise or lower the selected source resolution according to the required output. HDR10 support is explicitly listed, and the supplied technical data also states a maximum refresh rate of 85Hz. Together, the scaler’s resolution conversion, 4K@60 output capability, 4:4:4 color sampling and HDR10 support define its video-performance profile without relying on unspecified enhancement or processing features.

What Makes It Different

The defining characteristic of the VP-426C is the combination of three distinct input interfaces with bidirectional resolution scaling and one HDMI output. HDMI handles an established digital video path, USB Type-C accommodates a USB-C signal source, and VGA accepts computer-graphics signals. The selected input is processed through the same ProScale digital-scaling function, whether the required operation is upscaling or downscaling. This connector mix makes the model especially relevant when a system cannot be restricted to HDMI sources alone but still requires its processed output to use HDMI.

Final Assessment

The VP-426C offers a focused solution for selecting and scaling HDMI, USB Type-C and VGA video sources. Its documented strengths are specific: scaling up or down, output resolutions up to 4K@60 with 4:4:4 color, an 18Gbps maximum data rate, HDR10 support and HDMI output. For a system built around mixed source connections and a standardized HDMI destination, those capabilities provide a clear technical basis for choosing this model. Buyers requiring additional details such as physical dimensions, power specifications, included accessories or warranty coverage should verify them separately, as they are not supplied in the available product data.
