4K ProScale Receiver/Scaler with HDBaseT and HDMI Inputs

The Kramer VP-427X2 is a high-performance receiver, auto-switcher, and scaler designed for systems combining remote HDBaseT sources with a local HDMI source. Its three available inputs include two HDBaseT connections and one local HDMI connection. The unit can switch automatically or manually between those sources, then scale the selected signal for the connected HDMI display. Supported output scaling extends to 4K@60Hz with 4:4:4 color sampling.

Ideal Use Cases

The VP-427X2 is suited to video systems that need to select between two remotely delivered HDBaseT signals and a locally connected HDMI source. It also addresses installations where the source equipment and display are separated by long CAT copper cable runs or where incoming signals must be adapted to the display resolution.

• Systems requiring automatic selection among three video inputs.
• Installations combining two HDBaseT feeds with one local HDMI source.
• Long-reach video distribution requiring scaling at the receiving end.

Why Choose This Model

The VP-427X2 combines HDBaseT reception, HDMI source connectivity, input switching, and output scaling in one model. It supports both automatic and manual glitch-free switching, allowing the system to manage source changes automatically while preserving an option for direct user control.

Its scaler can either increase or decrease the incoming resolution. The output resolution can be selected manually, or the unit can automatically match its scaling to the resolution of the HDMI display connected at the output. This provides two clearly defined approaches to output management without limiting the installation to a fixed scaling mode.

Installation and Integration

For integration, the two HDBaseT inputs accommodate remotely transported signals while the local HDMI input provides a connection for nearby source equipment. The selected input is processed by the internal scaler before being delivered to the output display. Automatic display-resolution matching can simplify configuration when the desired result is alignment with the connected HDMI display, while manual scaling remains available when a specific output resolution is required.

At its stated extended-reach performance, the VP-427X2 can receive video over CAT copper cable at distances up to 180 meters. That maximum is specified for video up to 4K@60Hz with 4:2:0 color sampling and 24-bit-per-pixel color. The source data also identifies further reach for lower HD video resolutions, although it does not specify the corresponding maximum distance.

Performance Highlights

The scaler supports output resolutions up to 4K@60Hz with 4:4:4 color sampling. Because both upscaling and downscaling are available, the VP-427X2 can adapt differing source resolutions to the output requirement rather than operating only as a signal receiver or input selector.

Switching can be performed automatically or manually across all three inputs. The stated glitch-free switching capability is particularly relevant when multiple connected sources must share the same display path. The product title also identifies HDR capability, though no specific HDR formats are supplied in the source data.

What Makes It Different

The defining feature of the VP-427X2 is its combination of two HDBaseT inputs, a local HDMI input, three-input switching, and 4K scaling. It receives long-reach signals and performs resolution conversion within the same signal path, supporting installations that require more than straightforward HDBaseT extension.

Its automatic output-resolution matching is another practical distinction. Instead of requiring the output setting to be selected manually in every configuration, the scaler can follow the resolution of the connected HDMI display. Manual configuration remains available when display matching is not the preferred operating method.

Final Assessment

The VP-427X2 is a focused solution for systems that need to receive two HDBaseT sources, accept one nearby HDMI source, and route any of those inputs to an HDMI display with resolution scaling. Its combination of automatic or manual glitch-free switching, scaling through 4K@60Hz 4:4:4, and CAT cable extension up to 180 meters at the specified 4K format makes it well matched to long-reach, multi-source video integration.
