No, not all TVs have hdmi ports.
Early LCD TVs did not have hdmi ports, and now smart TVs have hdmi ports.
Now the HDMI interface is one of the necessary interfaces for TVs, which is the data interface used to connect devices such as set-top boxes and digital cameras.
It is usually used to input video and audio from other program source devices. The advantage is that only one HDMI cable can complete the transmission of video and audio signals.
In the past, old-fashioned TVs had to be connected to video cables and audio cables to the left and right. And that connection is still an analog signal, while HDMI is a digital signal without loss.
The HDMI interface has been improved many times since its introduction.
