What is the maximum FPS supported by HDMI?
The maximum FPS (frames per second) supported by HDMI depends on the version of the HDMI standard being used. For example, HDMI 1.4 can support up to 120 Hz at a resolution of 1080p, while HDMI 2.0 can support up to 240 Hz at the same resolution. However, the maximum FPS also depends on the resolution and the type of content being displayed.
In general, the higher the resolution, the lower the maximum FPS that can be supported by HDMI. For example, HDMI 2.1 can support up to 120 Hz at a resolution of 4K, but only up to 60 Hz at a resolution of 8K. It’s also worth noting that not all devices support the maximum FPS that their HDMI version is capable of, so it’s always a good idea to check the specifications of your device to see what it can handle.
What is the difference between HDMI 1.4 and HDMI 2.0 in terms of FPS?
HDMI 1.4 and HDMI 2.0 are two different versions of the HDMI standard, and they have different capabilities when it comes to FPS. HDMI 1.4 can support up to 120 Hz at a resolution of 1080p, while HDMI 2.0 can support up to 240 Hz at the same resolution. This means that HDMI 2.0 can display more frames per second than HDMI 1.4, which can result in a smoother and more responsive image.
In addition to the difference in FPS, HDMI 2.0 also supports higher resolutions than HDMI 1.4. For example, HDMI 2.0 can support resolutions up to 4K at 60 Hz, while HDMI 1.4 is limited to resolutions up to 4K at 30 Hz.

It’s also worth noting that not all games are optimized to take advantage of high frame rates, so even if your HDMI connection can support 120 Hz or 240 Hz, the game itself may not be able to display that many frames per second. In general, it’s a good idea to check the system requirements for your games to see what kind of HDMI connection is recommended.
Can HDMI support variable refresh rates (VRR)?
Yes, HDMI can support variable refresh rates (VRR), but only with certain versions of the standard. For example, HDMI 2.0 does not support VRR, but HDMI 2.1 does. VRR allows the display to adjust its refresh rate on the fly to match the frame rate of the content being displayed, which can help to reduce screen tearing and improve the overall viewing experience.
In order to take advantage of VRR over HDMI, both the display and the source device must support the feature. Additionally, the HDMI connection must be using the HDMI 2.1 standard, and the display must be capable of displaying the variable refresh rates. Not all devices support VRR, so it’s always a good idea to check the specifications of your device to see what it can handle.
How does HDMI 2.1 improve upon HDMI 2.0 in terms of FPS?
HDMI 2.1 improves upon HDMI 2.0 in several ways, including its ability to support higher frame rates. For example, HDMI 2.1 can support up to 120 Hz at 4K resolution, while HDMI 2.0 is limited to 60 Hz at the same resolution.
