Bandwidth Requirements for 120 FPS
To determine whether HDMI 2.0 can support 120 FPS, we need to calculate the bandwidth required to transmit video signals at this frame rate. The bandwidth required depends on several factors, including the resolution, color depth, and chroma subsampling.
Assuming a 4K resolution (3840 x 2160) and a color depth of 10 bits per pixel, the bandwidth required for 120 FPS can be calculated as follows:
- Pixel clock: The pixel clock is the clock frequency required to transmit the video signal. For 4K at 120 Hz, the pixel clock would be approximately 594 MHz.
- Bandwidth: The bandwidth required can be calculated by multiplying the pixel clock by the number of pixels per frame and the color depth. For 4K at 120 Hz, the bandwidth required would be approximately 32.4 Gbps.
As we can see, the bandwidth required for 120 FPS at 4K resolution exceeds the maximum bandwidth offered by HDMI 2.0 (18 Gbps). This suggests that HDMI 2.0 may not be able to support 120 FPS at 4K resolution.
Chroma Subsampling and Bandwidth Reduction
However, there is a way to reduce the bandwidth required for 120 FPS. Chroma subsampling is a technique used to reduce the amount of color data transmitted, which can help reduce the bandwidth required.
By using chroma subsampling, the bandwidth required for 120 FPS at 4K resolution can be reduced to approximately 24.3 Gbps. While this is still higher than the maximum bandwidth offered by HDMI 2.0, it is closer to the limit.
