Weighing 1.3 kg, it can be carried between rooms or taken on a trip. Its stated battery life is approximately two hours of playback without mains power.
Image and projection
The projector uses 0.23-inch DLP technology and an RGB laser light source. Its native resolution is 1920 × 1080 pixels, and its stated brightness is 800 ANSI lumens. It is therefore better suited to a dimly lit room or use at dusk than to bright daylight.
A color gamut figure of 110% of BT.2020 is stated. This should not be interpreted as more than 100% coverage, nor does the figure alone establish color accuracy. The available specifications do not explain how the figure was measured.
The Dolphin 2 supports HDR10, HLG and 4K video decoding. This means it can process supported 4K content, but displays it at its native Full HD resolution. The benefit of HDR will depend on the content and viewing conditions. The stated lifespan of the laser light source is approximately 30,000 hours.
The image size can be set from 20 to 120 inches. A throw ratio of 1.2:1 means the projector needs to be approximately 1.2 meters from the projection surface to produce an image one meter wide. When choosing a location, allow enough distance for the desired image width.
Battery and portability
The built-in battery has a capacity of 54 Wh and a stated playback time of approximately two hours. Actual battery life may vary depending on settings and use, so it is worth having a power supply available for longer sessions. The projector supports USB-C Power Delivery, for example from a compatible charger or power bank.
Dimensions of 185 × 179 × 58 mm and a weight of 1.3 kg make it easy to carry in a backpack. The built-in battery is useful for presentations, travel or an outdoor screening in the evening when a power outlet is not nearby.
Google TV and hardware
Google TV runs on a quad-core MT9630 Cortex-A53 processor, with 2 GB of RAM and 32 GB of internal eMMC storage. Google TV provides access to apps and streaming services, so a separate computer is not needed to play supported online content.
The projector supports voice control through Google Assistant and wireless screen mirroring via Google Cast, Miracast and AirPlay. Content from a compatible device can therefore be projected without a video cable.
Connectivity and audio
Wireless connectivity includes dual-band Wi-Fi on the 2.4 GHz and 5 GHz bands, plus Bluetooth 5.1. Wi-Fi connects the projector to a network for streaming, while Bluetooth can be used with compatible headphones or a speaker.
Wired connections include HDMI 2.1 with ARC, USB 2.0, USB-C with Power Delivery and a 3.5 mm audio output. HDMI can be used to connect a games console, for example, while ARC allows audio to be sent to a compatible audio device. The USB port can connect external devices such as storage drives.
Two built-in speakers provide 2 × 5 W of power and support Dolby Digital Plus. They can be used for everyday viewing or presentations; Bluetooth, HDMI ARC and the 3.5 mm output provide options for connecting external audio equipment.
