UGREEN CM619 HDMI Splitter 1 In 2 Out mirrors one HDMI source onto two screens at up to 4K 30Hz. It sells for KSh 3,000 at Mascom International, Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD. The unit arrives brand new and sealed, carrying a 340MHz internal amplifier, HDCP 1.4 handshake support, and a metal shell measuring 106 x 54 x 22mm. One HDMI input port feeds two HDMI output ports at the same time. The CM619 draws 5V through a micro-USB power input, so no bulky brick sits under your desk.
Boardroom presenters, church AV teams, university lecturers, sports bar owners, and console gamers all hit the same wall: one laptop, two screens, and no clean way to feed both. Unplugging cables between a projector and a TV wastes minutes in front of a waiting audience. The UGREEN CM619 removes that step. A worship team in Kasarani can run a hall projector and a stage monitor from one media PC. A supermarket in Nyeri can drive two signage panels from a single Android TV box. Gamers can mirror a PS5 to a TV and a capture monitor at once.
Unlike unbranded splitters sold from Nairobi's cheapest accessory stalls, the UGREEN CM619 carries a documented 10.2Gbps bandwidth rating, a metal enclosure that sheds heat, and a real warranty path. Users consistently report steady output over 15-metre HDMI runs where cut-price boxes fall to a black screen within minutes. At Mascom International, we're witnessing steady demand from schools, churches, and hotels moving to two-screen setups. Walk into our Kimathi Street store Monday through Saturday, 9:00 AM to 7:00 PM, to test the CM619 with your own laptop and cables. Countrywide pay-on-arrival delivery covers all 47 counties.
Common Questions About the UGREEN CM619 HDMI Splitter
What exactly does the UGREEN CM619 HDMI Splitter do?
It copies one HDMI signal and sends the identical picture and sound to two screens at the same time. Both outputs show matching content this is mirroring, not extending. The 340MHz internal amplifier rebuilds the signal before it leaves each output port, which is why longer cable runs stay stable. Connect your laptop, decoder, or console to the single input, then run HDMI cables to a TV and a projector. Both light up together with no switching required.
Does the CM619 support 4K, and at what refresh rate?
Yes, up to 3840 x 2160 at 30Hz. UGREEN's official specification lists HDMI 1.4 with 10.2Gbps of bandwidth, which caps 4K at 30 frames per second. At 1080p the unit runs a full 60Hz, and it also handles 1080i, 720p, 576p, and 480p sources. For films, slide decks, and DStv sport, 4K at 30Hz looks clean. For fast-moving 4K console gaming, set your output to 1080p 60Hz for smoother motion instead.
Can I extend my desktop across two different screens with this?
No. The CM619 mirrors only both screens receive the same image. Spreading your Windows or macOS desktop across two monitors needs a DisplayPort MST hub or a USB-C docking station, both stocked at Mascom International. Splitters and docks solve different problems. If you want a second workspace for spreadsheets beside email, ask our Kimathi Street team about a dock. If you want the same slide deck on two screens, this is the right box.
Which devices work with the CM619?
Any HDMI source: Windows and Mac laptops, desktop PCs, PlayStation 5 and PS4, Xbox consoles, DStv and GOtv decoders, Android TV boxes, Blu-ray players, DVRs, and CCTV recorders. On the output side it feeds TVs, computer monitors, and projectors. No drivers or software install is needed at either end. Kenyan buyers commonly pair it with a laptop feeding a boardroom projector plus a confidence monitor, or a decoder feeding two TVs in a bar.
How long can my HDMI cables be before the picture fails?
UGREEN rates the CM619 for roughly 40 metres at 1080p and about 20 metres at 4K, using good-quality cabling. Cable build matters more than raw length. Thin, unshielded HDMI cables sold at throwaway prices often fail past 10 metres, producing flicker or a blank screen. For church halls and lecture theatres running long ceiling drops, use certified High Speed HDMI cable. Mascom International stocks UGREEN HDMI cables from 1 metre to 20 metres at our Kimathi Street counter.
Does the CM619 need its own power supply?
Yes. The splitter draws 5V through a micro-USB power input, and it will not hold a stable signal without it. A phone charger, a spare USB port on your TV, or a laptop USB port all work as the source. Bus-powered splitters that skip external power are the main reason cheap units drop one output after a few minutes. Keep the power cable connected permanently in fixed installations such as signage or reception-area screens.
Why does one screen go black when I play Netflix or DStv content?
That is HDCP copy protection at work. The CM619 is HDCP 1.4 compliant, so it passes protected content correctly when both connected displays also support HDCP. If one screen is older or non-compliant, the handshake fails and that output stays dark. Test by swapping cables between the two output ports. Most TVs and monitors sold in Kenya since 2012 support HDCP 1.4. Older projectors in school halls are the usual culprit.
Is KSh 3,000 reasonable for an HDMI splitter in Kenya?
Yes, for a metal-cased, externally powered, branded unit. Unbranded plastic splitters sell for KSh 800 to KSh 1,500 around Nairobi, but they typically lack an amplifier, run hot, and fail within months. The CM619 works out to roughly KSh 8 per day across its first year. Weigh that against a failed presentation or a bar losing its match feed on a Saturday afternoon. Mascom International backs the unit with a warranty and a walk-in service desk.
How do I set up the CM619 for a church service or presentation?
Connect power first, then the source, then the displays. Plug the micro-USB cable into a 5V supply. Run an HDMI cable from your laptop or media PC into the input port. Run separate cables from the two output ports to the projector and the stage monitor. Set your laptop to Duplicate display mode, then switch on both screens. Setup takes under three minutes and needs no software. Our team can walk you through it on WhatsApp.
Technical Specifications
Core Splitting Function and Signal Amplification
- One HDMI Type A female input port accepts the source device, keeping cable routing simple in fixed installations
- Two HDMI Type A female output ports carry identical picture and audio to both connected screens
- 340MHz internal amplifier rebuilds signal strength on each output, holding picture stability across longer cable runs
- 10.2Gbps total throughput matches the HDMI 1.4 standard and covers every resolution the unit supports
- Mirroring only — outputs cannot show different content, which rules out multi-monitor desktop workspaces
- Splitting happens in hardware with no processing lag, so audio and video stay locked together
- Both outputs stay live at once, removing the cable-swapping routine during live presentations and church services
Resolution, Refresh Rates and Colour Depth
- 4K at 30Hz (3840 x 2160) is the ceiling, suitable for films, signage loops, and slide-based content
- 1080p at 24Hz, 50Hz, and 60Hz supported, covering PAL broadcast, cinema frame rates, and console output
- Backward compatible with 1080i, 720p, 576p, and 480p for older decoders and legacy projectors
- 12-bit deep colour handling produces smoother gradients on TV panels that accept extended colour data
- 3D format passthrough included for Blu-ray players and projectors still running stereoscopic content
- Resolution is set by your source device — the splitter passes through rather than upscaling or converting
- Both screens receive the same resolution, so match panel capabilities to avoid one display refusing the feed
Audio Formats and Content Protection
- DTS, DTS-HD, Dolby TrueHD, Dolby AC3, and LPCM 7.1 audio pass through untouched to both outputs
- Surround audio reaches AV receivers without downmixing, keeping home cinema setups working as intended
- HDCP 1.4 compliance handles encrypted content from DStv decoders, Blu-ray players, and streaming boxes
- Both connected displays must support HDCP, otherwise the non-compliant screen returns a blank output
- Audio and video travel on the same HDMI run, so no separate optical or 3.5mm cabling is required
- No audio extraction port — buyers needing separate sound feeds should ask about a dedicated HDMI audio splitter
Device and Display Compatibility
- Works with Windows laptops, MacBooks, desktop towers, and mini PCs through any standard HDMI output port
- PlayStation 5, PlayStation 4, Xbox Series consoles, and older Xbox hardware all feed the input without setup
- DStv, GOtv, StarTimes, and Zuku decoders connect directly, useful for bars running two screens off one subscription
- Android TV boxes, Chromecast dongles, and Blu-ray players are recognised immediately with no handshake delay
- CCTV DVRs and NVRs from Dahua, Hikvision, and similar brands output to a control room monitor plus a display screen
- Output side accepts TVs, computer monitors, and projectors of any brand carrying a standard HDMI input
- Plug-and-play across all platforms — no drivers, firmware, or configuration software to install anywhere
Build, Power and Cable Reach
- Metal alloy casing measuring 106 x 54 x 22mm sheds heat during continuous operation in warm equipment cabinets
- Roughly 90g in weight, light enough to sit behind a wall-mounted TV without needing a bracket
- Nickel-plated HDMI connectors resist corrosion in humid coastal conditions around Mombasa, Malindi, and Kilifi
- Micro-USB power input rated 5V/1A accepts a phone charger, TV USB port, or laptop USB port as the supply
- Rated for roughly 40 metres of cable run at 1080p and around 20 metres at 4K with quality cabling
