# 4K 240Hz KVM Bandwidth Calculator: Estimate Your Video Load

> Calculate the active-video estimate, identify whether the target is clearly demanding, then confirm that exact mode in the KVM and monitor documentation. Use the calculation to understand scale, then rely on the exact KVM mode table and complete signal chain for the purchase decision. The acceptance case is estimating how demanding a high-resolution high-refresh display mode is before routing it through a KVM. The failure to guard against is this: raw bandwidth arithmetic cannot prove a mode because blanking, link encoding, DSC, display timings and device-specific implementations change what a real connection can carry.
