Hi there! So, "HD ready" is a label that you might see on some TVs or other electronic devices. What it means is that the device is capable of showing video in high definition, which means the picture is very clear and detailed, like you're looking at real life.
However, being "HD ready" doesn't necessarily mean that the device can show the very best, highest quality form of high definition video called "Full HD" or "1080p". It just means that it can show video in some kind of high definition format, which is still pretty cool!
Overall, "HD ready" is a way of saying that a device can show clearer and more detailed video than older devices or ones that aren't designed to handle high definition.
