The UGREEN CM556 USB-C to DisplayPort Cable is in stock at Mascom International, priced at KSh 2,400, brand new and sealed. It runs 3m from a USB-C port straight into a DisplayPort 1.4 monitor, carrying up to 8K at 60Hz or 4K at 240Hz at a bandwidth of 32.4Gbps. The UGREEN CM556 USB-C to DisplayPort Cable supports HDR, HDCP 2.3 for protected streaming content, and DSC compression. Aluminium shells guard both plugs, and a nylon braid covers the lead. Collect it from our store in the Old Mutual Building on Kimathi Street, Nairobi CBD, or have it delivered anywhere in Kenya.

Built for gamers, video editors, developers and content creators across Kenya, the UGREEN CM556 USB-C to DisplayPort Cable fixes a common layout problem. A laptop on a stand and a large monitor on a wall arm often sit too far apart for a short adapter and the monitor's own cable. The UGREEN CM556 USB-C to DisplayPort Cable covers that distance in one piece, with no joint to work loose. A creator editing in a Kilimani apartment, or a trader in Upper Hill running charts on a 4K screen, gets the monitor's full refresh rate from a single USB-C port.

Unlike the thin, unbranded leads sold around River Road, the UGREEN CM556 USB-C to DisplayPort Cable carries DisplayPort 1.4 bandwidth across its full 3m length. Long cheap cables often force a monitor down to a lower refresh rate or cause the screen to blink off at random. At Mascom International, we're seeing more buyers pair a laptop with a 144Hz or 165Hz monitor, and this cable lets that setup run at full speed. Test it on a display at our Kimathi Street counter, or order on WhatsApp and pay on arrival.

Common Questions About the UGREEN CM556 USB-C to DisplayPort Cable

How much is the UGREEN CM556 USB-C to DisplayPort Cable 3m in Kenya?
The UGREEN CM556 USB-C to DisplayPort Cable 3m costs KSh 2,400, sealed and brand new, at Mascom International in Nairobi CBD. The price includes a 6-month warranty against manufacturing defects and pay-on-arrival delivery to any county, so you pay by cash or M-Pesa when it reaches you. It costs KSh 400 more than the UGREEN CM654 USB-C to DisplayPort Adapter and KSh 200 more than the UGREEN MM142 USB-C to HDMI Cable.

Should I buy the UGREEN CM556 cable or the UGREEN CM654 USB-C to DisplayPort Adapter?
Both carry the same signal: DisplayPort 1.4, 8K at 60Hz, 4K at 240Hz and 32.4Gbps. The difference is the shape. The UGREEN CM556 is one 3m cable, while the UGREEN CM654 is a 10cm adapter that needs a separate DisplayPort cable. Pick the CM654 for KSh 2,000 if your monitor came with a good DisplayPort 1.4 cable. Pick the CM556 if you need reach, have no spare cable, or want no extra joint.

What do HDR, HDCP 2.3 and DSC mean on the UGREEN CM556?
HDR lets a compatible monitor show brighter highlights and deeper shadows in games, films and photo edits. HDCP 2.3 is the copy-protection handshake that streaming apps check, so protected 4K content can play on the external screen. DSC, or Display Stream Compression, squeezes the video signal without visible loss, which is how the UGREEN CM556 reaches 8K and 4K 240Hz. Your laptop and monitor must support each feature for it to switch on.

Can the UGREEN CM556 run a 4K 144Hz or 1440p 240Hz gaming monitor?
Yes. The UGREEN CM556 supports up to 4K at 240Hz, so a 4K 144Hz or 1440p 240Hz monitor sits within its limits. The laptop's graphics chip must also output that mode through its USB-C port, which most recent gaming laptops with a direct USB-C link to the graphics card do. Once connected, set the refresh rate in Windows display settings, and switch on G-Sync or FreeSync in the graphics driver if the monitor offers it.

Will the UGREEN CM556 USB-C to DisplayPort Cable work with a MacBook?
Yes, the UGREEN CM556 works with every MacBook Air and MacBook Pro that has USB-C or Thunderbolt ports, as these send DisplayPort video natively. macOS detects the monitor within seconds. How many external screens you can run depends on the Mac's chip rather than the cable; base M1 and M2 models support one. Studio Display and Pro Display XDR owners should note those screens take Thunderbolt input, not DisplayPort.

How does the UGREEN CM556 handle heat, dust and power cuts in Kenya?
The nylon braid on the UGREEN CM556 resists fraying where the cable bends behind a desk, and the aluminium plug shells handle the warmth of offices in Mombasa or Industrial Area well. Fine Nairobi dust can loosen a connection over time, so clean both ports every few weeks. During a KPLC outage, the cable keeps working as long as the laptop and the monitor still have power, for example through a UPS.

Is 3m too long for a normal desk setup?
For a single desk with the monitor right beside the laptop, the UGREEN CM556's 3m length can leave slack to tidy with a cable tie. That length pays off with a laptop on a side table, a monitor on a wall arm, or a desk with a PC tower underneath. It also suits a living room where a laptop feeds a DisplayPort monitor from the sofa. For short runs, the 10cm UGREEN CM654 adapter keeps things neater.

Who should buy the UGREEN CM556 USB-C to DisplayPort Cable, and who should skip it?
Buy the UGREEN CM556 if your monitor has DisplayPort, your laptop sends video over USB-C, and the two sit more than an arm's length apart. Gamers, editors, developers and anyone driving a high-refresh screen will use what it offers. Skip it if your screen is a TV or projector with HDMI only; the UGREEN MM142 USB-C to HDMI Cable fits that job. Skip it too if you already own a good DisplayPort 1.4 cable.

Technical Specifications

Core Function
  • DisplayPort 1.4 standard — the input most high-refresh gaming and colour-work monitors use for their best picture.
  • 8K at 60Hz — four times the detail of 4K, for 8K monitors driven by a capable laptop graphics chip.
  • 4K at 240Hz — sharp detail with 240 frames every second, so fast games and quick scrolling stay smooth.
  • 32.4Gbps bandwidth — the full data rate of DisplayPort 1.4, held over the whole 3m length.
  • HDR support — compatible monitors show brighter highlights and deeper shadows in games, films and photo edits.
  • HDCP 2.3 — the copy-protection check streaming apps require before playing protected 4K content on an external screen.
  • DSC (Display Stream Compression) — squeezes the signal without visible loss, which unlocks 8K and 4K 240Hz output.

Compatibility
  • USB-C ports with DisplayPort Alt Mode — the laptop sends native video through USB-C, so no driver or app is needed.
  • Thunderbolt 3, Thunderbolt 4 and USB4 ports — all carry DisplayPort video and work with the UGREEN CM556.
  • MacBook Air and MacBook Pro with USB-C — plug in directly; the chip decides how many external screens run at once.
  • Gaming laptops from ASUS ROG, Lenovo Legion, MSI and HP Omen — many wire a USB-C port to the graphics card.
  • Any monitor with a full-size DisplayPort input — plugs straight in with no adapter on the monitor end.
  • Charge-only USB-C ports will not work — some budget laptops send no video, so test before buying if unsure.

Build
  • Aluminium plug shells — metal housings on both ends that resist knocks and shed warmth better than plastic.
  • Nylon braided lead — a woven jacket that stands up to bending, kinking and repeated packing and unpacking.
  • 3m length — reaches from a laptop stand to a wall-mounted monitor or across a corner desk.
  • Black finish — matches most monitor stands and desk setups; confirm stock on WhatsApp before you travel in.
  • Reversible USB-C plug — goes in either way up, which helps when reaching behind a laptop on a crowded desk.

Inclusions
  • The UGREEN CM556 USB-C to DisplayPort Cable, 3m, sealed in UGREEN retail packaging.
  • No power adapter — the cable carries video and sound only and does not charge your laptop.
  • No software to install — Windows and macOS detect the monitor as soon as both ends connect.
  • 6-month Mascom International warranty, set out in full in the Warranty section below.
  • Testing at the counter — try it with your own laptop on a monitor at our Kimathi Street store before you pay.

Package Contents

The sealed box contains the UGREEN CM556 USB-C to DisplayPort Cable, a single 3m lead with a USB-C plug at one end and a DisplayPort plug at the other. Because the cable connects end to end, you do not need a separate adapter or a second cable. No charger or power supply is included, since the cable carries picture and sound only. Ask our team on WhatsApp if your laptop needs a charger to go alongside it.

Warranty

The UGREEN CM556 USB-C to DisplayPort Cable comes with a 6-month Mascom International warranty covering manufacturing defects under normal use, such as a plug that stops making contact or a signal that drops out. Claims are handled at our Nairobi CBD service desk in the Old Mutual Building on Kimathi Street.
