Aurzen D1R vs HAPPRUN K7 Pro: Which Projector Fits Your Room?

The D1R integrates Roku TV; the K7 Pro integrates Google TV. Choose the system that carries the apps and interface you actually want. Check campus network sign-in and account requirements before relying on either in a dorm. SWG has not tested streaming speed, app availability, or campus Wi-Fi compatibility.

Aurzen lists 280 ANSI lumens for the standard D1R. HAPPRUN rates the K7 Pro at 3000 ANSI lumens. Both figures come from the brands, and we have not independently measured either unit. We cannot convert these listings into a real-world brightness ratio or promise a usable image in a bright room.

For either model, control ambient light where possible and consider your intended screen size. A larger image can look dimmer from the same projector. The K7 Pro's marketing position does not establish daylight performance.

Aurzen lists the D1R at 3.1 lb / 1.4 kg (manufacturer-listed) and 9.1 × 7.5 × 3.2 in (manufacturer-listed). The K7 Pro manual copy lists 7.05 lb (K7 Pro manual) and 11.34 × 10.43 × 4.47 in (K7 Pro manual). Those documented differences make the D1R easier to plan around when moving or storing it. They do not measure carry comfort or durability.

The K7 Pro is a more natural fit for a stable shelf or another planned location. In either case, leave room for ventilation, a power connection, and a clear projection path.

Both records list automatic focus and keystone features. The K7 Pro manual also describes electric focus and keystone adjustment. These features do not remove the need to measure throw distance and wall or screen size. SWG has not timed either setup process.

Aurzen lists a 1.28:1 throw ratio for the D1R, but its product page gives conflicting 60–150-inch and 60–200-inch projection ranges. The reviewed K7 Pro documentation does not establish a throw ratio. Confirm placement using your room measurements and current model-specific guidance before buying.

Aurzen explicitly lists a native 1920 × 1080 panel for the D1R. The K7 Pro manual copy lists 1920 × 1080 resolution. HAPPRUN's “4K supported” wording describes accepted or decoded content, not a native 4K display. These records do not establish a picture-quality winner for color, contrast, sharpness, motion, or processing.

Aurzen lists two 5W speakers for the D1R. HAPPRUN lists two 10W speakers for the K7 Pro, and both brands list Dolby Audio. The K7 Pro has more listed speaker power, which can matter to a buyer planning a more permanent setup, but wattage is not a sound-quality or loudness test. SWG has not listened to either projector.

Aurzen documents one HDMI 1.4 port, one USB 2.0 port, and one audio output on the D1R. The K7 Pro manual copy lists one HDMI and one USB input plus a 3.5mm headphone output. Check the output and adapter requirements of your laptop, console, or streaming device before relying on a particular connection.

Neither pick guarantees an image size or viewing quality in your room. Measure the location and check your lighting, power, and shared-space constraints first.

Research checked: October 2026. Product identities and images come from existing Article 11 research. We used Aurzen's standard D1R product page, HAPPRUN's K7 Pro page, and a K7 Pro manual copy hosted by the independent Manuals+ site. The manual names model K7 Pro and lists its resolution, dimensions, weight, and ports; its independent host is identified so readers can judge provenance.

SWG has not personally tested image quality, brightness, audio, fan noise, throw distance, streaming, or long-term reliability. HAPPRUN's brightness figure is a manufacturer claim. Earlier price snapshots are omitted because prices change.

Choose the D1R when a compact, lighter Roku projector is the practical match for a shared or frequently rearranged room. Consider the K7 Pro when Google TV, its listed audio hardware, and a more permanent setup align with your plans. Portability favors D1R; neither source record supports a hands-on picture or sound-quality winner.
