How to test hdmi cable?

     Most people only observe the picture with the naked eye whether there are snowflakes and stripes, and roughly judge whether the cable is good or bad, but it is far from enough. The first step of professional testing is to rely on the professional equipment - Hdmi Cable tester. This kind of small instrument can be called "fire eye", which can detect the interface connection stitch by stitch and accurately solve hidden problems such as false welding and short circuit. Connect the two ends of the cable to the tester separately, and the indicator light will turn on instantly. According to the manual, the flashing law will be compared. In just a few minutes, the integrity of the line will be clear at a glance.

    It is not enough to have no problem with optical and wired, and the quality of signal transmission is the core. The second step is to use professional software to run bandwidth testing. Software like "HDMITest" can simulate 4K, 8K or even 10K video streaming with one click, and monitor frame rate and resolution in real time. If the frame rate is unstable and the picture resolution decreases, it means that the cable bandwidth is insufficient and it is difficult to carry high image quality. It is time to upgrade the cable.

    Finally, don't forget the actual combat simulation. Connect the game console and turn on high-frame-rate competitive games; or play high-code-rate Blu-ray movies to immersively feel the smoothness and colour accuracy of the picture. After all, the use experience in the real scene is the "ultimate examination room" for testing HDMI cables.

    Master this set of testing methods, no longer be "cheated" by poor-quality cables, and exchange it for a cinema-level visual feast at the lowest cost. From now on, take the initiative to make every HDMI cable in the home stand the severe test of image quality.
