Resolution:

• Look for at least 1080p (Full HD) for clear images.
• Consider 4K if budget allows, especially for movies or detailed presentations.

Brightness:

• Measured in lumens; a higher lumen count (around 3000-4000 for well-lit rooms) is better for bright environments.

Contrast Ratio:

• A higher contrast ratio (e.g., 2000:1 or more) enhances image quality, providing deeper blacks and vibrant colors.

Throw Distance:

• Determine the space where you'll use the projector. Short-throw projectors are suitable for small rooms, while long-throw projectors are for larger spaces.

Portability:

• If you plan to move the projector frequently, consider weight and size. Mini projectors are ideal for travel.

Connectivity Options:

• Check for HDMI, USB, and wireless connectivity. Compatibility with devices (laptops, streaming devices, etc.) is essential.

Lamp Life:

• Look for projectors with longer lamp life (up to 20,000 hours) to reduce maintenance and replacement costs.

Audio Quality:

• Built-in speakers may not provide quality sound; consider external audio options if needed.

Aspect Ratio:

• Standard is 16:9 for movies; ensure compatibility with the content you’ll project.

User Reviews and Brands:

• Research brands and read reviews to find reliable models; trusted brands may provide better support and warranty.

Budget:

• Set a budget but be cautious about compromising quality. Cheaper models may incur additional costs in the long run.

Usage Environment:

• Identify where you'll use the projector (home theater, office, outdoors) and choose a model tailored for that setting.

Keystone Correction and Lens Shift:

• These features help adjust the image for proper alignment, especially in awkward setups.

Warranty and Support:

• Check warranty terms and customer support options for peace of mind.

Test Before Buying:

• If possible, test the projector to ensure it meets your expectations in terms of image quality and features.
