The 3-metre length solves a specific Kenyan office problem desks where the monitor sits across the room from the docking station, or home setups where the laptop charges on one side of the room while the screen lives on a separate wall mount. Generic 1-metre cables force users into awkward layouts; the UGREEN CM556 3M lets the cable run behind furniture cleanly.

Common Questions About the UGREEN CM556
What does the UGREEN CM556 3M cable do?
The UGREEN CM556 carries video and audio from a USB-C device to a DisplayPort monitor across 3 metres of cable length. It supports up to 8K resolution at 60Hz refresh rate, 4K at 240Hz for gaming monitors, and 2K at 360Hz for esports panels. The cable handles Dynamic HDR, HDCP 2.3 content protection, eARC audio passthrough, and Display Stream Compression for high-bandwidth signals. A single cable replaces the need for adapters, dongles, or docks when connecting a USB-C laptop to a DisplayPort monitor.
Is the UGREEN CM556 uni-directional or bi-directional?
The CM556 model variant supports uni-directional transmission only signal flows from USB-C source to DisplayPort display, not the reverse. This matches how most Kenyan users connect laptops to external monitors. The USB-C end plugs into your MacBook, Dell XPS, ThinkPad, Galaxy Tab, or iPhone, and the DisplayPort end goes into the monitor. UGREEN sells a separate bidirectional CM556 variant for users who need DisplayPort-to-USB-C signal flow, though this is less common in typical office setups.
Will the UGREEN CM556 work with my MacBook Pro and Dell monitor?
Yes. The UGREEN CM556 connects to any MacBook Pro, MacBook Air, iMac, or Mac Mini with USB-C or Thunderbolt 3/4 ports, and outputs to Dell UltraSharp, Dell S-series, or Dell U-series monitors with DisplayPort 1.4 inputs. The cable supports macOS Clamshell mode, letting the MacBook stay closed while driving an external display. Windows laptops including Dell XPS, HP Spectre, HP EliteBook, Lenovo ThinkPad, ASUS ZenBook, Surface Laptop, and Razer Blade also work without driver installation.
Can the UGREEN CM556 run 4K at 144Hz for gaming?
Yes, the UGREEN CM556 handles 4K resolution at 144Hz and 240Hz refresh rates for gaming monitors. The 32.4Gbps DisplayPort 1.4 bandwidth supports high frame rates with G-Sync and FreeSync compatibility for tear-free gameplay. Kenyan gamers running ROG Ally, Steam Deck via dock, or USB-C-equipped gaming laptops connected to Samsung Odyssey, LG UltraGear, ASUS ROG Swift, or Dell Alienware monitors get full refresh-rate performance. Display Stream Compression keeps signal integrity across the full 3-metre length without quality loss.
Does the cable support Samsung DeX and iPad Pro display modes?
Yes. The UGREEN CM556 supports Samsung DeX on Galaxy S22, S23, S24, S25, S26 series and Galaxy Tab S7, S8, S9, S10, S11 series for desktop-mode workflows on external monitors. iPad Pro models with USB-C or Thunderbolt connectors output video through the same cable. iPhone 15 Pro, 15 Pro Max, 16 Pro, 16 Pro Max, 17 Pro, and 17 Pro Max also send display output to DisplayPort monitors, useful for presentations or photo review on larger screens.
Why is the 3-metre length better than shorter cables?
The 3-metre run gives flexibility for office and home setups where the monitor and the source device cannot sit close together. Boardrooms with wall-mounted displays, home studios where the desk faces a separate monitor stand, recording setups with cameras between the laptop and screen, and dual-monitor configurations all benefit from the extra reach. Display Stream Compression and proper shielding keep the signal clean across 3 metres cheaper unbranded long cables typically drop signal or flicker at this length.
How does the UGREEN CM556 compare to USB-C hubs and docks?
A USB-C hub or dock adds USB ports, Ethernet, and SD card slots but typically caps video output at 4K 60Hz through HDMI. The UGREEN CM556 dedicates the full 32.4Gbps DisplayPort 1.4 bandwidth to video alone, reaching 8K 60Hz or 4K 240Hz that hubs cannot match. For users who only need single-monitor video and use the laptop's native USB-A ports for peripherals, the CM556 cable costs less than a dock and delivers better display performance.
What is the warranty and where do I get support in Kenya?
The UGREEN CM556 carries a 12-month UGREEN manufacturer warranty against defects, processed through Mascom International's Nairobi CBD service desk. Cable damage from rough handling, kinks, or pet chewing falls outside warranty coverage. Mascom International provides direct after-sales support at the Kimathi Street store without sending the cable back to a distant service centre. Keep the original packaging for warranty claims.
