Sony production of electronic products have many kinds, television sets, mobile phones, projector apparatus and so on. So what do you know about Sony projectors ? Today, the editor will take you to understand how to buy a Sony projector? And what are the tips when buying?
1. Check the horizontal scanning tracking frequency range
According to the horizontal scanning frequency range given in the technical indicators, select high, medium and low frequencies from the middle to calculate the image resolution corresponding to the three frequency points. Check whether the projector can display normally under these three resolutions. If the line is out of synchronization, that is, the screen twists or shakes, etc., it means that the horizontal scanning and tracking are poor.
2. Check the focusing performance with a projector
Use the projector to check the focus performance, adjust the focus to the position, change the image contrast from low to high, and observe whether the horizontal and vertical lines of the square are defocused. If there is, it indicates poor focusing performance.
3. Check the video bandwidth
The video bandwidth directly affects the details of the video. Use a computer or signal generator to generate a white background graphic signal with a resolution that the projector can reach. Observe whether the smallest character graphic on the screen is clear. For example, when the video bandwidth of the projector is insufficient, the horizontal lines displayed on the screen are solid, while the vertical lines are dull, and the image details are blurred.
These are the tips for buying Sony projectors that I have shared with you. I hope they will help you.
