Mascom International stocks the UGREEN CM455 HDMI Extender at KSh 8,000, brand new and sealed, as a matched transmitter and receiver pair. It carries 1080P video at 60Hz plus digital audio over a single Cat5e or Cat6 network cable for up to 70 metres. That is more than three times the 20 metres a good HDMI cable manages on its own. The UGREEN CM455 HDMI Extender reads the screen's settings automatically and needs no software or drivers. It is on the shelf at our store in the Old Mutual Building on Kimathi Street, Nairobi CBD.
Designed for churches, schools, hotels, restaurants and event crews, the UGREEN CM455 HDMI Extender handles the long video runs a normal cable cannot reach. A sound desk at the back of a church hall can feed a projector at the front. A hotel in Mombasa can place its decoder in the reception office and show matches on a bar screen across the lobby. The UGREEN CM455 HDMI Extender also lets security teams send a CCTV recorder's view to a guard room downstairs. Network cable is cheap, thin and easy to run through ceilings and trunking.
Unlike other electronics retailers in Kenya that sell unbranded extender kits with no support, Mascom International supplies the genuine UGREEN CM455 HDMI Extender with a 6-month warranty and a real counter for any claim. Buyers throughout Kenya report that the kit saves them from buying a second decoder or computer just to put a picture in another room. Our team can talk you through cable choice and placement before you buy. Visit the store, or order on WhatsApp for pay-on-arrival delivery to all 47 counties, arriving the same day within Nairobi and its environs.
Common Questions About the UGREEN CM455 HDMI Extender
How much does the UGREEN CM455 HDMI Extender cost in Kenya?
The UGREEN CM455 HDMI Extender costs KSh 8,000 brand new at Mascom International in Nairobi CBD. That price buys both units, the transmitter that sits by your source and the receiver that sits by your screen. It also includes a 6-month warranty handled at our walk-in service desk. The network cable that joins them is bought separately, cut to the length your building needs. Payment happens on arrival, so you check the kit before handing over any money.
Is the UGREEN CM455 HDMI Extender better than a wireless HDMI extender?
The UGREEN CM455 HDMI Extender gives a steadier picture than a wireless kit because a physical cable cannot suffer radio interference. Wireless extenders skip the cable run, but walls, steel roofing and busy Wi-Fi in town buildings can cause dropouts and delay. The CM455 also reaches 70 metres on cable, further than most wireless sets claim. Choose a wireless kit for a quick temporary setup where running cable is impossible. Choose the CM455 for permanent installations in churches, schools and hotels where the picture must never cut out.
How does the UGREEN CM455 HDMI Extender cope with Kenyan buildings and power cuts?
The UGREEN CM455 HDMI Extender works over the same Cat5e or Cat6 cable that most Kenyan offices already run through their trunking for internet. During a KPLC outage the kit stops along with the screen, then reconnects without any setup once power returns. Put both the source and the extender on a UPS if a live service or meeting cannot afford a gap. In dusty venues in Nakuru or Machakos, keep both units on a shelf rather than the floor and use cable with sealed RJ45 connectors.
Who should buy the UGREEN CM455 HDMI Extender, and who should skip it?
Buy the UGREEN CM455 HDMI Extender if you need to send one full HD source to a screen or projector between 20 and 70 metres away. It suits churches, conference rooms, sports bars, classrooms and CCTV control rooms. Skip it if your screen sits within 15 metres of the source, since a quality HDMI cable does the job for less. Skip it too if you need 4K, because this kit tops out at 1080P; a 4K-rated extender is the right tool there.
Which network cable works best with the UGREEN CM455 HDMI Extender?
The UGREEN CM455 HDMI Extender works with Cat5e or Cat6 cable, and Cat6 is the safer choice for the full 70-metre run. Use one unbroken length from the transmitter to the receiver, because routers, switches and wall patch panels in between can break the signal. Solid copper cable performs better than cheaper copper-clad aluminium, which loses strength over long distances. Mascom International can advise on the right reel length for your hall or office before you order the kit.
Does the UGREEN CM455 HDMI Extender carry sound as well as picture?
Yes, the UGREEN CM455 HDMI Extender carries audio along with the video on the same cable, up to 192kHz at 24-bit. It passes PCM, DTS, DSD and Dolby AC-3 formats, including 5.1 and 7.1 surround. That means a soundbar or amplifier at the receiver end plays the full soundtrack of a match or film. Automatic EQ adjustment keeps the signal clean over long runs. For churches and event venues, the sound reaches the screen in step with the picture, with no separate audio cable needed.
Can the UGREEN CM455 HDMI Extender work with a DStv decoder, laptop or CCTV recorder?
Yes, the UGREEN CM455 HDMI Extender connects any HDMI source, including DStv and GOtv decoders, laptops, desktop PCs, media players, gaming consoles and CCTV recorders. On the screen side it works with TVs, monitors and projectors. HDCP 1.4 support lets protected decoder channels and streaming apps play rather than show a blank screen. EDID handling reads what the display can show and sets the best resolution for you. Plug it in and it works, with no drivers on your laptop or settings menu to configure.
Can I connect an HDMI cable on either end of the UGREEN CM455 HDMI Extender?
Yes, each end of the UGREEN CM455 HDMI Extender uses a standard HDMI cable to reach the source and the screen. UGREEN recommends HDMI cables of up to 20 metres with 26AWG pure copper wire on these short links. Adding a few metres on each side lets you hide the units behind a cabinet or above a ceiling board. Most setups need only short HDMI leads, and Mascom International stocks HDMI cables in several lengths at the same counter.
Technical Specifications
Core Function and Video
- Transmitter and receiver pair — the transmitter sits by the source and the receiver sits by the screen, linked by one cable.
- Up to 70 metres over a single network cable — enough to cross a church hall, school compound block or hotel lobby.
- 1080P full HD at 60Hz — a clear, smooth picture for football, presentations, sermons and menu boards on large screens.
- 3D video support — passes 3D content from players and sources that send it, for screens that can display it.
- EDID read and write — the kit learns what the screen can show and sets the right resolution automatically.
- Automatic EQ adjustment — tunes the signal strength over long runs so the picture and sound stay clean at the far end.
Audio
- Digital audio up to 192kHz at 24-bit — studio-grade sound quality travels with the picture on the same cable.
- PCM, DTS and DSD formats — covers the sound types used by decoders, media players and music sources.
- Dolby AC-3 with 5.1 and 7.1 surround — a home theatre or bar sound system plays full surround from the far screen.
- No separate audio cable needed — saves running a second line through ceilings, walls and trunking.
- Sound stays in step with the picture — lip movements and speech line up, which matters for preaching and live events.

- Connects decoders, PCs, laptops, media players, gaming consoles and CCTV recorders — any HDMI source can feed the transmitter.
- Feeds TVs, monitors and projectors — the receiver drives any display with an HDMI input.
- Plug and play — no drivers, apps or settings menus, so non-technical staff can set it up.
Build and Inclusions
- Grey housing built for frequent plugging and unplugging — holds up to event crews setting up and packing down each week.
- Standard RJ45 network port on each unit — the familiar internet plug, so any network technician can terminate the cable.
- HDMI cable support up to 20 metres with 26AWG pure copper — extra slack on each side for hiding units out of sight.
- Compact paired units — small enough to tuck behind a TV, inside a cabinet or above a ceiling board out of sight.

- 6-month Mascom International warranty — covers manufacturing defects, with claims handled at our Nairobi CBD service desk.
