Bandwidth Formula:
From: | To: |
Monitor bandwidth refers to the amount of data required to refresh a display per second. It's calculated based on horizontal resolution, vertical resolution, refresh rate, and color depth, determining the data transfer rate needed for smooth video output.
The calculator uses the bandwidth formula:
Where:
Explanation: The formula calculates the raw data rate required to refresh the display by multiplying the total pixels, refresh rate, and color depth, then converting from bits to bytes.
Details: Accurate bandwidth calculation is essential for selecting appropriate display cables, graphics cards, and ensuring smooth video performance without artifacts or dropped frames.
Tips: Enter horizontal and vertical resolution in pixels, refresh rate in Hz, and color depth in bits. All values must be positive integers.
Q1: Why divide by 8 in the formula?
A: The division by 8 converts the result from bits per second to bytes per second, which is the standard unit for data transfer rates.
Q2: What is typical bandwidth for modern monitors?
A: Bandwidth varies widely: 1080p@60Hz with 8-bit color requires about 3.2 Gbit/s, while 4K@144Hz with 10-bit color can exceed 40 Gbit/s.
Q3: How does this relate to display interface standards?
A: Different interfaces (HDMI, DisplayPort) have maximum bandwidth limits. This calculation helps determine if a specific interface can support your desired resolution and refresh rate.
Q4: Does this account for compression or overhead?
A: No, this calculates raw bandwidth. Actual requirements may be higher due to protocol overhead, or lower with compression technologies like Display Stream Compression (DSC).
Q5: Why is bandwidth important for gaming?
A: Higher bandwidth enables higher resolutions, faster refresh rates, and better color depth - all crucial for immersive gaming experiences.
