It's important for consumers to check the specifications and included accessories of the TV they are purchasing to ensure it is compatible with their desired devices and content.

A 4k upscaler works through an HDMI interface by taking a lower resolution video signal, such as 1080p or 720p, and using sophisticated algorithms to interpolate and upscale the image to 4k resolution. This process involves adding additional pixels to the original image to increase its overall resolution, resulting in a sharper and more detailed picture. The 4k upscaler then outputs the upscaled signal through the HDMI interface to a 4k display, allowing viewers to enjoy content at a higher resolution than its original source. This can be particularly useful when watching older or lower resolution content on a 4k television or monitor. **

Traditional copper HDMI cables may experience signal loss or degradation over such a long distance, whereas fiber optic cables can maintain the integrity of the 4K signal. Therefore, using a fiber optic HDMI cable for a 20 meter long 4K HDMI transmission is the best option to ensure high-quality video and audio. **
