This article will provide you with a detailed analysis of the key parameters of the projector to help you make an informed choice.
- Resolution
Resolution is one of the important parameters to measure the image quality of projector. It refers to the number of pixels that the projector can display. Common resolutions are:

4K UHD (3840×2160) : Suitable for high-end home theater and professional use.
When choosing a resolution, it should be determined according to your usage needs and budget.
Step 2: Brightness
Brightness, in lumens, indicates the clarity of the projector under specific light conditions. The higher the brightness, the better the projector performs in bright environments. Common brightness ranges are:
1000-2000 lumens: Suitable for dark rooms or light-controlled environments.
2000-3000 lumens: Suitable for medium light environments such as home theaters and small meeting rooms.
3000 lumens and above: Suitable for bright environments such as large meeting rooms and classrooms.
When choosing brightness, consider the light conditions in which you will be using the projector.
- Contrast
Contrast is the difference between the brightest white and darkest colors shown by the projector. The higher the contrast, the better the layer and detail. Common contrast ranges are:
1000:1: Suitable for basic business and educational use.
2000:1-5000:1: Suitable for home theater and high quality video playback.
10,000:1 and above: Suitable for high-end home theater and professional use.
High-contrast projectors perform especially well in dark room environments.
- Projection distance and projection ratio
The projection distance refers to the distance between the projector and the projection screen, while the projection ratio refers to the ratio of the projection distance to the width of the projected picture.
The projection ratio can be divided into:
Standard projection ratio (1.5:1-2.5:1) : Suitable for most household and business uses.
Short focus projection ratio (0.5:1-1.4:1) : Suitable for small Spaces, such as small conference rooms and classrooms.
Ultra short focus projection ratio (below 0.4:1) : Suitable for very small Spaces, such as educational interactive whiteboards.
When choosing the projection ratio, it should be determined according to the size of the space you use.
- Connect ports
The connection interface determines which devices the projector can connect to. Common connection interfaces are:
HDMI: Suitable for connecting HD devices such as Blu-ray players, game consoles and computers.
VGA: Suitable for traditional computer connections.
USB: Suitable for directly playing the content of the storage device.
Wi-Fi: Suitable for wireless connectivity and streaming.
When choosing a connection interface, consider the type of device you will be using and the connection needs.
- Lamp life
Bulb life refers to the time the projector bulb is used before it needs to be replaced. Common bulb life is:
2000-3000 hours: Suitable for general household and business use.
4000-6000 hours: Suitable for heavy use environments.
LED and laser projectors: Lamp life can reach more than 20,000 hours, suitable for long-term use.
When choosing lamp life, you should consider your frequency of use and maintenance costs.
Choosing the right projector for you requires a comprehensive consideration of key parameters such as resolution, brightness, contrast, projection distance, connection interface and bulb life. Make the most appropriate choice according to your specific use needs and budget. I hope the analysis of this article can help you, so that you can buy a projector more comfortable.
