Image, brightness and contrast
The native resolution of 1920 × 1080 pixels is suitable for watching films and videos or displaying presentations. Support for 4K means the projector can process that content; the resulting image is adapted to its Full HD resolution.
The listed brightness figures are 9,800 lumens and approximately 380 ANSI lumens. These figures are not automatically interchangeable: without knowing the measurement methods, it is not possible to determine a conversion between them. The projector can be used with some ambient light, but it will produce the best results in a dark or dimly lit room.
The stated contrast ratio is 12,000:1, and brightness uniformity exceeds 70%. Contrast describes the difference between the light and dark parts of an image, while brightness uniformity indicates how brightness varies across the projected area. Ambient light and the projection surface also affect the result.
Processor, system and multimedia
The BW-V8 uses an Allwinner H713 processor with a quad-core ARM Cortex-A53 CPU and a system based on Android 11. The system adds the option to use apps, though availability and compatibility depend on the individual app and service.
The projector supports the following multimedia formats:
- Video: MPEG-1, MPEG-2, MPEG-4, H.263, H.264, H.265 and VC-1.
- Audio: MP3, WMA, OGG, AAC and FLAC.
- Images: JPG, PNG and BMP.
This format support allows various videos, music files and photos to be played without always needing to convert them. Playback of a particular file can still depend on its encoding and the player used.
Image size and placement
The projector measures 215 × 170 × 86 mm and weighs 1,240 g, making it relatively easy to move between rooms or carry to an office.
The stated image diagonal is 30 to 150 inches, and the projection distance is 1.5 to 5 metres. The 1.2:1 throw ratio describes the relationship between the projector’s distance from the screen and the image width, not its diagonal. At a distance of 1.5 metres, that ratio gives an image width of approximately 1.25 metres; at 5 metres, it gives approximately 4.17 metres. The stated distance and diagonal ranges therefore should not be assumed to have corresponding endpoints without further verification.
Image adjustment includes manual focus and vertical keystone correction of ±15°. Keystone correction helps adjust the shape of the image when the projector is not at a suitable height relative to the screen or wall.
Connectivity and sound
The built-in 5 W speaker provides a basic source of sound. External speakers can be connected through the audio output or via Bluetooth.
The projector has HDMI 1.4, USB 2.0, an AV input, a TF card slot and an audio output. HDMI can be used to connect a computer or media player, for example, while USB and TF cards provide options for media playback. Wireless connectivity includes 2.4 GHz and 5 GHz Wi-Fi and Bluetooth 4.2.
The BW-V8 combines Full HD projection, 4K content processing and several playback options. When considering it, allow for suitable room darkening and check the relationship between the desired image size and available distance before planning its placement.
