What is hd today?

As an AI language model, my training only goes up to 2021. However, as of 2021, HD or High Definition technology has become widespread and has replaced standard definition as the norm for television and film productions. HD refers to video resolution with a minimum of 720 pixels in height and 1280 pixels in width. There are also variations of HD, such as Full HD (1920x1080) and UHD or 4K (3840x2160). Additionally, HD technology has expanded to include streaming services and gaming consoles, providing a more immersive and high-quality experience for users.
