If you want to own a projector with excellent performance, before buying a projector, understand the purchase parameters, at least it can help you make some choices.
- Brightness: Measured in lumens, it basically refers to the amount of light a projector can produce. If you plan to use the Pericat projector in a well-lit room, look for a projector with a higher brightness rating.
- Resolution: Resolution refers to the number of pixels that make up an image. The most common resolutions are 720p, 1080p, and 4K. The higher the resolution, the clearer the image.
- Lamp Life: Lamp life refers to the lifespan of the lamp in a projector. The longer the lamp life, the less frequently you need to replace the lamp.
- System configuration: At present, most projectors have a system like a computer, and their CPU configuration has 2 cores; 4 cores; 6 cores; 8 cores. For example, the Meigao G20S projector uses an 8-core CPU, which is fast and does not freeze when watching online movies.
- Dual WIFI or single WIFI: Most modern projectors have built-in systems and can connect to the Internet on their own. Some only work with 2.4G WiFi, while others support both 2.4G and 5.0G. 5.0G is much faster, but 2.4G works better through walls. For best results, it’s recommended to choose a projector that supports both types of WiFi.
- Contrast: Contrast is a key factor in determining the quality of a projector. A higher contrast ratio results in better picture layering and depth. A contrast ratio of 3000:1 is generally sufficient, but many projectors now offer ratios of 5000:1 to 10000:1.
With these parameters in hand, you can make an informed decision when purchasing, as owning a high-quality projector will enhance your viewing and presentation experience.
