What resolutions are supported by High-resolution HDMI?

High-resolution HDMI supports a range of resolutions, notably including 4k and 8k. HDMI specifications have evolved to accommodate higher resolutions due to advancements in display technology and the demand for better visual quality.

4k resolution provides a significantly clearer image compared to lower resolutions, making it ideal for modern TVs and displays. Additionally, 8k resolution takes this a step further, offering even more detail and a sharper image for compatible devices.

The other options are limited to lower resolutions. For example, 1080p provides good quality but doesn't encompass the capabilities of high-resolution HDMI. Similarly, 720p and lower resolutions like Standard Definition do not take full advantage of what high-resolution HDMI is designed to deliver. Therefore, 4k and 8k are the correct answers as they fully utilize the potential of high-resolution HDMI technology.
