VX1UHD V-by-One to HDMI 2.0 Converter Board, 51-Pin Input, Up to 4K 60Hz, No Audio

Overview

The VX1UHD converts V-by-One signals from compatible TV mainboards into HDMI output. It is designed for reusing mainboards from TVs with damaged screens and for compatible display signal conversion applications. The board features a 51-pin V-by-One input and a standard HDMI Type-A female output, supporting up to 4K at 60Hz. Verify the source connector, pinout and signal format before use. Compatibility cannot be determined from the TV brand or model alone.

Features

1. V-by-One to HDMI conversion for connecting a compatible TV mainboard to an HDMI display.

2. HDMI 2.0 output supporting up to 4K at 60Hz. Actual output depends on the input signal.

3. Configurable input with 4 or 8 lanes, 24- or 30-bit data and 1 or 2 partitions. Non-default formats require solder configuration as described in the supplier manual.

4. Powered through the 51-pin display cable, typically at 10V or 12V. No separate power supply is needed when the source power and pinout are correctly matched.

5. Compact 80 × 60 mm PCB with signal detection and MCU status indicators.

Specifications

Compatibility and Setup

Use with a compatible mainboard, display cable and HDMI display.

The VX1UHD is not a 4K-to-1080p downscaler; a 4K input remains 4K after conversion, requiring a downstream display that accepts HDMI 2.0 4K input.

The default configuration is 8 lanes, 30 bits and 1 partition. Short P1/R17 for 4 lanes, P2/R18 for 24 bits, or P3/R19 for 2 partitions, using a zero-ohm resistor or solder bridge as specified in the manual.

Select the 51-pin cable to match the TV mainboard connector. Type A uses a latch. For non-latching connectors, select Type B for a 27.5 mm plug width or Type C for 29.5 mm. Each kit includes one cable of the selected type.

Cable Selection

Select the cable to match the V-by-One output connector on the customer's TV mainboard. The converter board remains the VX1UHD no-audio version.

Type A: Latching plug for the corresponding latching connector. The reference image does not specify the Type A plug width.

Type B: Non-latching plug, 27.5 mm wide.

Type C: Non-latching plug, 29.5 mm wide.

First check whether the connector uses a latching design. Compare a latching connector with Type A. For a non-latching connector, measure the original cable plug width and compare it with Type B or Type C.

The 27.5 mm and 29.5 mm measurements refer to plug width, not cable length. Physical fit alone does not confirm compatibility; also verify the 51-pin pinout, power supply and V-by-One signal format.

If unsure, provide clear photos of the mainboard connector and original cable plug, together with the measured plug width, for compatibility checking.
