Buying Guide
- Brightness and ambient light: For bright rooms or outdoor daytime use, aim for 4500–5000 ANSI lumens or higher. In darker rooms, 2000–3500 ANSI lumens can suffice.
- Resolution and color: 4K support with HDR10+ improves detail and color. A wider color gamut (near 99.8%) helps achieve cinema‑like accuracy.
- Autofocus and keystone: TOF or autofocus features speed setup and maintain a rectangular image across distances. Auto keystone reduces manual adjustments.
- Smart features: Built‑in streaming apps reduce the need for external sticks. Check for licensing (Prime Video, YouTube) and automatic updates.
- Office and living room use: Consider throw distance, screen size, and room layout. Short throw or ultra‑short throw options help in smaller rooms.
- Portability and setup: If you plan outdoor use, look for an adjustable stand and weather‑resistant components. A 360° stand increases placement options.
- Durability and warranty: Review component quality, heat management, and service terms for long‑term use.
