Smart TVs are modern televisions that are equipped with internet connectivity and advanced features, such as the ability to stream content from popular platforms like Netflix, Hulu, and Amazon Prime. Some smart TVs also have the ability to play Blu-ray discs, which are high-definition disc format that offers improved picture and sound quality compared to traditional DVDs. To play a Blu-ray disc on a smart TV, the TV must have a built-in Blu-ray player or a separate external Blu-ray player must be connected to the TV via an HDMI port. It is important to check the specifications of your specific smart TV model to determine if it is capable of playing Blu-ray discs.
