Cheerlux CL770 4000 Lumens LED Full HD Android WiFi ATV Projector

The Cheerlux CL770 is a premium, feature-packed LED Full HD Android WiFi ATV Projector designed for users who want a true home theatre experience without investing in a commercial-grade setup. With native 1920 x 1080 Full HD resolution, 4000 lumens of brightness, an integrated Android 9.0 smart system, built-in dual-band Wi-Fi, and a built-in Analog TV tuner, the CL770 functions as a projector, smart entertainment hub, and live TV receiver all in one compact unit. Capable of projecting up to a massive 280-inch screen, it is equally suited for home cinemas, classrooms, and small conference rooms — making it one of the most capable mid-range projectors available in Bangladesh today.

Display Technology and Image Quality

The Cheerlux CL770 uses an LCD panel combined with a high-efficiency LED lamp and a high-transmittance multi-layer coated optical glass lens to produce images with outstanding clarity and colour accuracy. With a 2500:1 contrast ratio and 16.7 million colours, the projector delivers deep blacks, vivid highlights, and true-to-life colour reproduction across all types of content. Like all projector-based displays, the CL770 uses diffuse reflection imaging — projecting light off a surface rather than directly at the viewer — which is considerably gentler on the eyes during extended viewing sessions compared to traditional screens.

Native Full HD Resolution and Brightness

Unlike budget projectors that upscale 720p content, the Cheerlux CL770 features a true native resolution of 1920 x 1080 pixels, delivering sharp, detailed Full HD images without any loss of clarity or softness at the edges. It also supports 4K UHD input via HDMI, making it compatible with the latest media players, gaming consoles, and streaming devices. At 4000 lumens, the CL770 produces bright, clear images even in rooms with moderate ambient light — eliminating the need to fully black out a room for a comfortable viewing experience.

Projection Size and Distance

The Cheerlux CL770 supports a screen size range of 55 to 280 inches, with an optimal display size between 60 and 120 inches for the sharpest image quality. The recommended projection distance is 2.5 to 5 metres, making it a natural fit for living rooms, bedrooms, classrooms, and small conference spaces. With a throw ratio of 1.4:1, manual vertical keystone correction of ±15°, and electronic digital keystone correction via the remote, achieving a perfectly proportioned and distortion-free image is quick and effortless regardless of the room layout.

Android 9.0 Smart System and Wireless Streaming

Powered by Android 9.0 with 1GB RAM and 8GB ROM, the Cheerlux CL770 provides direct access to the Google Play Store, YouTube, Netflix, Prime Video, and a wide range of other streaming apps — no external streaming box or smart TV required. The integrated dual-band Wi-Fi (2.4GHz and 5GHz) ensures fast, stable wireless connectivity for buffer-free HD streaming. Wireless screen mirroring is supported via AirPlay for iOS devices and Miracast/DLNA for Android, making it simple to cast videos, presentations, games, and photos from any smartphone or tablet directly to the big screen. Bluetooth support allows users to pair wireless speakers or headphones for enhanced audio quality without cables.

Built-in Analog TV Tuner (ATV)

The Cheerlux CL770 includes a built-in Analog TV tuner with a dedicated RF port for direct cable or dish antenna connection. This allows users to receive and watch live broadcast television through the projector without needing a separate set-top box, consolidating multiple entertainment devices into a single, streamlined setup and delivering genuine value for households and shared spaces.

Connectivity

The CL770 offers a comprehensive set of wired ports including 2 × HDMI, 2 × USB, 1 × VGA, 1 × AV, and a 3.5mm headphone output jack — ensuring compatibility with a wide range of devices including laptops, desktop computers, smartphones, tablets, gaming consoles, and DVD players. The dual HDMI and dual USB ports make it especially convenient in multi-device environments, while Bluetooth connectivity adds wireless flexibility for audio output. The unit operates on a universal power input of AC 90V–240V, making it compatible with power supplies across Bangladesh and internationally.

Audio

The Cheerlux CL770 is equipped with dual channel stereo speakers (2 × 3W / 4 Ohm), delivering noticeably fuller and more balanced audio than the single-speaker setups found in most budget projectors. For an even richer listening experience, users can connect external speakers via the 3.5mm audio jack or wirelessly through Bluetooth. Supported audio formats include MP3, WMA, LPCM, MPEG1, and MPEG2 — covering all commonly used audio file types without requiring additional software.

LED Lamp Life and Energy Efficiency

Driven by a high-efficiency 132W LED light source, the Cheerlux CL770 achieves an impressive lamp life of up to 50,000 hours — equivalent to over 17 years of daily four-hour use. This eliminates the recurring cost and inconvenience of lamp replacements associated with traditional projectors, making the CL770 a financially sound long-term investment for both home users and educational institutions. The high-efficiency heat dissipation system keeps the unit cool and quiet during operation, with fan noise maintained at under 28dB.

Large-Format Projection and Portable Design

With the ability to project up to a 280-inch screen, the Cheerlux CL770 is one of the largest-capable projectors in its class — making it suitable not just for home theatres but also for small conference halls, seminar rooms, and outdoor viewing events. Despite its powerful output, the unit measures just 31.0 × 22.9 × 10.3 cm and weighs 2.3 kg, keeping it manageable and portable. Built from industrial-grade ABS plastic, it is robust enough for regular transport and repositioning. It supports four projection modes — front, rear, ceiling mount, and tabletop — with two spare support screws included for flexible height and angle adjustment.

3D Support and Multimedia Formats

The Cheerlux CL770 supports Red-Blue anaglyph 3D playback for an immersive home 3D viewing experience. It handles a comprehensive range of video formats including MP4, MKV, AVI, MPEG1, MPEG2, H.264, H.263, HEVC, MJPEG, AVS, VC1, RV30, and RV40 — as well as image formats such as JPEG, PNG, BMP, MPO, and GIF. This broad format compatibility ensures smooth, hassle-free playback from USB drives and connected devices without any additional conversion tools or software.
