HDMI (High-Definition Multimedia Interface) is a digital video interface standard that connects devices such as Blu-ray players, gaming consoles, and computers to display devices like TVs and monitors. HDMI cables transmit audio and video signals between devices, allowing for a seamless entertainment experience.
Refresh rates, on the other hand, refer to the number of times a display updates the image on the screen per second. Measured in Hertz (Hz), refresh rates directly impact the smoothness and fluidity of the visual experience. The higher the refresh rate, the more frames are displayed per second, resulting in a more realistic and immersive experience.
The most common refresh rates found in modern displays are:
- 60 Hz: The standard refresh rate for most TVs and monitors, suitable for general use and casual gaming.
- 120 Hz: A higher refresh rate, ideal for fast-paced content, such as sports, action movies, and competitive gaming.
- 240 Hz: An even higher refresh rate, typically found in high-end gaming monitors, providing an ultra-smooth experience.
The Quest for 120 Hz HDMI
So, can you get 120 Hz HDMI? The answer is yes, but with some caveats.
In theory, HDMI 2.0 supports up to 120 Hz at 4K resolution. However, there are some limitations and requirements to achieve this:
HDMI 2.0 and 2.1: The Key to 120 Hz
HDMI 2.0, released in 2013, was the first version to support 4K resolution at 60 Hz. Later, HDMI 2.1, released in 2017, introduced several new features, including support for higher refresh rates.
