The HannStar K MV-4 94V-0 is a specialized embedded motherboard form factor commonly found in All-in-One (AIO) desktop computers, particularly those manufactured by HP and Compaq during the early-to-mid 2010s. While often referred to generically as a "motherboard," it is technically a system board tailored for specific chassis configurations where space and thermal efficiency are prioritized over upgradeability.
This write-up explores the specifications, design philosophy, and practical considerations for this specific hardware component.
The HannStar K MV-4 94V-0 motherboard will never win a performance award. It lacks the high-end capacitors of Asus, the overclocking features of DFI, or the reliability of Intel’s own boards. But it represents a massive slice of computing history. hannstar k mv-4 94v-0 motherboard
Millions of budget PCs, school computer labs, and office workstations ran on this green, unassuming uATX board. Its UL 94V-0 fire rating made it a safe choice for cramped cases. Its Socket 478 supported two decades of software evolution (from Windows 98 to Linux Lite).
If you have one sitting in an e-waste pile, consider this: Recapped and paired with an SSD (via PCI-IDE adapter), it makes an excellent low-power writing machine or a vintage DOS gaming hub. Respect the board for what it is—a durable, safety-certified survivor of the Pentium 4 era. The HannStar K MV-4 94V-0 is a specialized
Final Verdict: The HannStar K MV-4 is not a treasure, but it is a reliable tool. And for the niche community of retro PC builders, that reliability is worth its weight in gold.

Hannstar is not a brand most gamers recognize, but it is a giant in the OEM (Original Equipment Manufacturer) world. HannStar Display Corporation is a Taiwanese company primarily known for manufacturing LCD panels. However, like many Asian electronics giants, they have produced or contracted the production of motherboards for mass-market systems—particularly for Compaq, HP, Acer, and various no-name white-box desktops sold in emerging markets during the early 2000s to 2010s.
| Parameter | Details | |-----------|---------| | PCB Size | ~75mm x 50mm (small form factor) | | Chipset (common) | Realtek, MStar, or Novatek microcontroller | | Max Resolution | Up to 1920x1080 (1080p) or 1440x900 depending on firmware | | LVDS Type | Single or Dual channel (jumper selectable) | | Panel Voltage | 3.3V or 5V (selectable via jumper for different LCDs) | | Operating Temp | 0°C to +60°C |
Because Hannstar produced multiple "K MV-4" variants for different OEMs (e.g., HP Compaq dx series, eMachines, or Acer Aspire T-series), specifications can vary slightly. However, based on PCB layouts, component placement, and BIOS dumps from repair forums, the most common configuration is as follows.
