Using the precise **VESA CVT-RBv1** timing standard to determine required capacity for advanced video mixers.
Calculation Results
Total Pixel Clock (PClk):
(Calculated using the **VESA CVT-RBv1** formula: $\frac{(W+160) \cdot (H+17) \cdot R}{10^6}$ MHz)
Required Mixer Capacity:
Required Connector Standard
*Note: Connector limits are simplified based on maximum 4:4:4 Pixel Clock (PClk) capacity. Actual support may vary based on color depth and signal type (e.g., 4:2:0, 4:2:2).
Capacity Thresholds Explained (Professional AV Context)
Standard / HD Capacity: For standard $1080\text{p}$ and $1920 \times 1200 @ 60 \text{ Hz}$ signals. These use the basic, most common capacity inputs.
(PClk $\le 165 \text{ MHz}$)
DL (Dual Link) Capacity: Required for higher resolutions like $2560 \times 1600 @ 60 \text{ Hz}$ or $4\text{K}$ signals running at a slower frame rate ($\le 30 \text{ Hz}$). This capacity is also limited to signals less than $4096 \text{ px}$ wide.
($165 \text{ MHz} < PClk \le 340 \text{ MHz}$ AND Width $\le 4096 \text{ px}$)
4K Capacity: The highest single-cable capacity, necessary for full $4\text{K}@60 \text{ Hz}$ signals **OR** any ultra-wide or unusual resolution (e.g., $4608 \times 960$) that exceeds $4096 \text{ pixels}$ in width, even if the frame rate is low.
(PClk $> 340 \text{ MHz}$ **OR** Width $> 4096 \text{ px}$)
Advanced / Multi-Link: Signals that exceed the maximum single-cable capacity, typically requiring specialized connections (like HDMI $2.1$ or DisplayPort $1.4$) or multiple linked cables to handle extremely high data rates (e.g., $8\text{K}$ or $4\text{K}@120 \text{ Hz}$).
(PClk $> 600 \text{ MHz}$)
