The UGREEN CM429 HDMI Repeater is in stock at Mascom International, priced at KSh 2,400, brand new and sealed, with 4K support and a built-in signal amplifier chip. Long HDMI cables lose strength as distance grows, and the picture starts to flicker, blank out or show white sparkles. The UGREEN CM429 HDMI Repeater sits between two cables and boosts the signal so a run can stretch up to 40 metres. It has an HDMI female port on each side and works as plug and play. You can collect it from our Old Mutual Building shop on Kimathi Street, Nairobi CBD.
Built for AV technicians, church media teams, school ICT staff and event planners across Kenya, the UGREEN CM429 HDMI Repeater solves one common headache. A projector mounted at the back of a hall in Kisumu, or a TV on the far wall of a Westlands boardroom, often sits too far from the laptop for one cable to carry a stable signal. Rather than moving equipment or buying a costly extender kit, you join two HDMI cables through this small adapter. The amplifier chip restores the signal, so slides, sermons, match screenings and CCTV feeds reach the display without dropouts.
Unlike other electronics retailers in Kenya that sell plain HDMI couplers labelled as boosters, Mascom International stocks the genuine UGREEN CM429 HDMI Repeater with its amplifier chip inside. A plain coupler only joins cables. It adds length but no strength, so the picture often fails on long runs. Customers across Nairobi tell us the UGREEN CM429 HDMI Repeater fixed screens they had nearly given up on in lecture rooms, restaurants and hotel function rooms. Visit our Kimathi Street shop to test it with your own cables, or order on WhatsApp for pay-on-arrival delivery anywhere in the country.
Common Questions About the UGREEN CM429 HDMI Repeater
How much is the UGREEN CM429 HDMI Repeater in Kenya?
The UGREEN CM429 HDMI Repeater costs KSh 2,400 brand new at Mascom International on Kimathi Street, Nairobi CBD. That price includes a 6-month warranty against manufacturing defects and pay-on-arrival delivery to any county. HDMI cables are not part of the price, so bring or buy the two lengths your run needs. If you need one source feeding two screens instead of one far screen, the UGREEN CM619 HDMI Splitter costs KSh 3,000, a gap of KSh 600.
How far can the UGREEN CM429 HDMI Repeater extend an HDMI signal?
The UGREEN CM429 HDMI Repeater lets an HDMI run reach up to 40 metres in total, thanks to its built-in amplifier chip. You connect one cable from the source into one side and a second cable from the other side to the display. The chip strengthens the weakened signal at the join. Real reach depends on cable quality, so thick, well-shielded HDMI cables give the best result. For runs close to the limit, test the full setup before fixing cables inside a ceiling or trunking.
What is the difference between the UGREEN CM429 HDMI Repeater and the UGREEN CM619 HDMI Splitter?
The UGREEN CM429 HDMI Repeater boosts one signal over distance, while the UGREEN CM619 HDMI Splitter copies one signal to two screens. The repeater has one input and one output and costs KSh 2,400 at Mascom International. The splitter has one input and two outputs, supports 4K at 30Hz and costs KSh 3,000. Pick the repeater when one display sits too far away. Pick the splitter when two displays must show the same picture, such as a lobby TV and a reception monitor.
Will the UGREEN CM429 HDMI Repeater work with Kenyan TVs, decoders and power supply?
Yes, the UGREEN CM429 HDMI Repeater works with devices that have a standard HDMI port, including TVs, projectors, laptops, DStv and GOtv decoders, and gaming consoles sold in Kenya. It needs no driver or app. Kenya uses 240V mains with UK-style three-pin plugs, but this adapter connects only through its two HDMI ports. During KPLC power cuts, plug your source and display into a UPS so the whole chain keeps running and a surge does not reach your equipment.
Does the UGREEN CM429 HDMI Repeater support 4K video?
The UGREEN CM429 HDMI Repeater supports 4K resolution, so an Ultra HD laptop, streaming stick or console can pass its picture through the join. 4K carries about four times the detail of Full HD 1080p. Long 4K runs are harder on cables than 1080p runs, so use cables rated for 4K on both sides. If a 4K picture flickers near the 40-metre limit, setting the source to 1080p can steady it while you upgrade a cable.
Who should buy the UGREEN CM429 HDMI Repeater, and who should skip it?
Buy the UGREEN CM429 HDMI Repeater if one display sits beyond the reach of a single HDMI cable, as in churches, lecture halls, bars, conference rooms and CCTV control desks. It suits installers who want a low-cost, quick fix without pulling new network cable. Skip it if you need the picture on several screens at once; the UGREEN CM570 HDMI Splitter handles four displays. Skip it too if your source and screen sit within a few metres, where one good cable is enough.
Can I use the UGREEN CM429 HDMI Repeater with a projector in a church or lecture hall?
The UGREEN CM429 HDMI Repeater suits church and lecture hall projectors in Kenya, where the laptop sits at the front and the projector hangs at the back. Join two HDMI cables through it and route them along the wall or ceiling. Media teams in Nakuru, Eldoret and Nairobi use this kind of setup for worship lyrics, sermon notes and lecture slides. Keep the adapter somewhere reachable, not sealed inside plaster, so you can check the connection if the picture ever drops.
Why does my long HDMI cable flicker, and will the UGREEN CM429 HDMI Repeater fix it?
A long HDMI cable flickers because the digital signal weakens with distance until the display cannot read it cleanly. The UGREEN CM429 HDMI Repeater fixes this by amplifying the signal at the join between two cables. Typical symptoms include a blank screen that comes back, white sparkles, wrong colours or sound cutting out. Adding a plain coupler only lengthens the problem. If a damaged connector causes the flicker, no booster will help, so our Kimathi Street staff can test your cable before you buy.
Technical Specifications
Core Function and Signal Amplification
- Built-in signal amplifier chip — strengthens a weakened HDMI signal so the display receives a clear, readable picture again.
- Total HDMI reach of up to 40 metres — enough to cross most church halls, boardrooms and restaurant floors in one run.
- 4K resolution support — Ultra HD video passes through the join, with about four times the detail of Full HD 1080p.
- One input and one output — this is a booster for a single display, not a splitter that feeds several screens.
- Plug and play operation — no driver, app or settings menu; connect both cables and the picture appears on screen.
- Cuts flicker, sparkles and dropouts — the usual signs that a long HDMI run is losing signal strength along the way.
Compatibility With Common Devices
- Works with standard HDMI sources — laptops, desktop PCs, DStv and GOtv decoders, streaming sticks, CCTV recorders and gaming consoles.
- Feeds any HDMI display — TVs, projectors, computer monitors and security screens in homes, offices, schools and venues.
- Joins two HDMI cables of your choice — pick lengths that match the room rather than hunting for one fixed long cable.
- Fits home and commercial setups alike — from a sitting-room wall mount to a hotel conference room or sports bar.
- Full-size HDMI connectors — standard cables plug straight in; a mini or micro HDMI source needs a separate converter first.
Build and Design
- HDMI female port on each side — both cables plug directly into the body, with no fixed pigtail lead to snap off.
- Compact housing — small enough to sit behind a TV, inside cable trunking or above a ceiling board out of sight.
- Inline placement — the unit hangs at the join between two cables, so no shelf, screw or wall bracket is needed.
- Black finish — blends in with standard black HDMI cables running along walls, skirting and ceilings in finished rooms.
- No buttons or switches — nothing to configure, so staff without technical training can install it in minutes.
Inclusions and Setup Needs
- Ships as the UGREEN CM429 HDMI Repeater unit in sealed UGREEN retail packaging, ready to install the same day.
- HDMI cables sold separately — you need two, one running to each side of the repeater from source and display.
- Use 4K-rated cables for Ultra HD runs — thinner, low-cost cables may cut the usable reach or drop the resolution.
- Matching HDMI cables available at Mascom International — our staff can advise lengths that keep your run within 40 metres.
- Backed by a 6-month Mascom International warranty covering manufacturing defects, with claims handled at our Nairobi CBD desk.
Package Contents
Inside the sealed UGREEN box you get the UGREEN CM429 HDMI Repeater unit itself. HDMI cables do not come in the box, because every installation needs different lengths on each side. Mascom International stocks HDMI cables in several lengths at our Kimathi Street shop, so you can buy the repeater and both cables in one visit. If you are unsure which lengths your room needs, send us the distance on WhatsApp and our staff will suggest a pairing that stays within the 40-metre reach.
Warranty
The UGREEN CM429 HDMI Repeater ships with a 6-month warranty through Mascom International, covering manufacturing defects under normal use. If the unit develops a fault within that period, bring it with your receipt to our service desk at the Old Mutual Building, Kimathi Street, Nairobi CBD, and our team will assess the claim.
