Today, with the rapid development of digital technology, traditional display connection methods are undergoing significant changes. In the past, many users relied on HDMI to HDMI cables to stream audio and video content from their computers to their TVs. However, as laptop designs have evolved, more and more well-known manufacturers such as Apple, Dell, and Lenovo have begun to eliminate HDMI ports. . Although this change weakens users' playback options to a certain extent, it does not mean that the possibility of video projection is completely lost.
The emergence of USB-C to HDMI adapter effectively solves this problem. It brings users a more immersive audio-visual experience by connecting the USB-C end to the laptop and the HDMI end to the TV. With the variety of USB-C to HDMI adapters on the market, consumers need to pay attention to two main indicators when choosing: resolution and refresh rate. Adapters currently on the market generally support both 4K 30Hz and 4K 60Hz specifications. Although 60Hz is better than 30Hz in the-ory, this is not always the case in practical applications, which makes consumers need to consider comprehensively.
Frame rate and refresh rate greatly affect the video experience. Frame rate (fps) refers to the number of frames that the video source can display per second, while refresh rate (Hz) is the number of frames per second that the monitor can display. If the refresh rate is lower than the frame rate, screen tearing and blurring may occur. Therefore, in home entertainment, choosing the right TV and adapter has become particularly important.
For most users, a 30Hz refresh rate is sufficient for watching TV shows and movies. However, with new TVs generally featuring 60Hz or 120Hz refresh rates, consumers may experience slight picture jitter when watching 24fps movies. This is because 60Hz TVs have to use "3:2 pull-down" technology when displaying 24fps content, which alternates certain frames multiple times, which can lead to a loss of smoothness. In contrast, a 120Hz TV can better handle 24fps movies, allowing the playback effect to maintain its original artistic effect.
In short, although technological advancements have gradually replaced HDMI ports, USB-C to HDMI adapters provide users with a new solution. When choosing an adapter, consumers should carefully consider resolution and refresh rate to ensure the best audio-visual experience. With appropriate choices, users can still enjoy high-quality video entertainment without being limited by technological evolution.
