1. What is Monitor Bandwidth?

Monitor bandwidth refers to the amount of data required to display a particular resolution at a given refresh rate and color depth. It's crucial for determining the capabilities of display connections like HDMI or DisplayPort.

2. How Does the Calculator Work?

The calculator uses the bandwidth formula:

Where:

• \( H \) — Horizontal resolution in pixels
• \( V \) — Vertical resolution in pixels
• \( Refresh \) — Refresh rate in Hz
• \( BPP \) — Bits per pixel (color depth)

Explanation: The formula calculates the raw data rate required to transmit the video signal, accounting for resolution, refresh rate, and color depth.

3. Importance of Bandwidth Calculation

Details: Knowing the bandwidth requirement helps determine if a particular resolution/refresh rate combination is supported by your display connection (HDMI, DisplayPort) and graphics card.

4. Using the Calculator

Tips: Enter horizontal and vertical resolution (e.g., 1920×1080), refresh rate (e.g., 60, 144), and bits per pixel (typically 8 for standard color depth). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is typical BPP for modern monitors?
A: Most modern monitors use 8 bits per pixel per channel (24-bit color), but some high-end displays use 10 bits (30-bit color).

Q2: How does compression affect bandwidth?
A: Technologies like Display Stream Compression (DSC) can reduce the actual bandwidth needed, allowing higher resolutions on existing connections.

Q3: What bandwidth does 4K@60Hz require?
A: 3840×2160 at 60Hz with 8 BPP requires about 12.54 Gbps uncompressed bandwidth.

Q4: What are common bandwidth limitations?
A: HDMI 2.0 supports up to 18 Gbps, while DisplayPort 1.4 supports up to 32.4 Gbps.

Q5: Does this account for blanking intervals?
A: No, this calculates raw pixel data. Actual signal bandwidth may be slightly higher due to blanking intervals.
