Note: While the native resolution is WUXGA (1920 × 1200), the unit supports scaling to 1080p, 4K (via HDMI 2.0) and even 8K input (down‑scaled), making it compatible with modern media sources. and 8K support

Gamers and home‑theater enthusiasts appreciated the low input lag (≈ 4 ms in “Game Mode”) and high refresh‑rate support up to 120 Hz over HDMI 2.0. When paired with an ALR screen, the projector achieved deep blacks comparable to entry‑level OLED TVs, while retaining the large‑screen immersion (120‑inch at 2.5 m). 1 × DisplayPort 1.4

| Issue | Impact | Mitigation | |-------|--------|------------| | Price – ~US $7,800 (incl. accessories) | Higher than basic encoders | Justified by dual‑engine, AI, and 8K support; bulk licensing discounts available. | | Heat – 300 W can raise chassis temperature to ~45 °C in confined racks | May require additional rack cooling | Recommended 1‑U front‑to‑back airflow or optional fan‑module. | | Learning Curve – HeyOS UI is feature‑rich; new users may need training | Longer onboarding | Heydouga provides free 2‑day on‑site training and a comprehensive knowledge base. | | Limited 3rd‑Party Codec Support – No native support for proprietary codecs (e.g., Sony XDCAM). | May need transcoding | Can be handled upstream or via optional software license (HeyCodec +). |

For small‑room deployments, the 10‑W stereo speakers can deliver acceptable sound without an external PA system, though professional installations will typically use dedicated audio gear.
