Model and loading comparison
Reference: the three original V2.0 specifications dated September 1, 2017. Dimensions below are width × height in pixels.
| Model | Single color | Dual color | Tricolor | Module interfaces |
|---|---|---|---|---|
| HD-E62 | 1024 × 64 or 2048 × 32 | 512 × 64 | 672 × 32 | 4 HUB12 + 2 HUB08 |
| HD-E63 | 1024 × 128 | 512 × 128 | 672 × 64 | 8 HUB12 + 4 HUB08 |
| HD-E64 | 1024 × 256; maximum width noted as 2048 | 512 × 256 | 672 × 128 | 1 × 50-pin interface |
The E64 maximum-width note is not a statement that 2048 × 256 is supported. Confirm the complete width/height arrangement and scan method.

Sign layout and installation
Programs can use independent areas with borders and effects. The manuals describe timed playback, button controls, clock formats, count-up/countdown functions and brightness adjustment. Choose the required sensors and external controls separately.
Before replacement, record the exact card model, sign color mode, resolution, scan method and HUB wiring. Keep the working program and screen parameters, then check compatibility against the corresponding PDF.

Frequently asked questions
What is the difference between E62, E63 and E64?
They differ in loading and connectors. E62 has 4 HUB12 and 2 HUB08 ports; E63 has 8 HUB12 and 4 HUB08 ports; E64 uses one 50-pin interface. Use the comparison table to match color mode and screen dimensions.
Can I update programs using a USB drive?
Yes. All three V2.0 documents list USB-drive and Ethernet program updates. Use Ethernet for PC configuration and network management; confirm which setup functions are available through USB.
Which software do these cards use?
The retained V2.0 specifications name HD2016. Confirm the compatible software release for the actual card firmware before replacing or updating an existing installation.
Are these full-color video controllers?
The specifications focus on single-color, dual-color and tricolor information displays. Their seven-color display feature is not a promise of full-color video playback; verify the module and content requirements.
Can the sign show temperature and humidity?
Yes, with the appropriate external sensor module. The sensor connections are documented, but the sensor is not established as included with every order.
