Video timing calculator

Enter horizontal and vertical resolution plus refresh rate to compute CVT, CVT-RB, and CVT-RBv2 timings in the browser. DMT and CEA-861 entries are looked up from standard timing tables. The Custom column accepts manual edits for side-by-side comparison or bespoke modelines.

Usage

ItemDescription
Preset resolution / refreshTwo dropdowns; refresh options depend on the selected resolution; choose None (manual) to edit numeric fields directly.
Visible columnsUse checkboxes to show or hide CVT, CVT-RB, CVT-RBv2, CEA-861, DMT, and Custom.
DMT / CEA-861Refresh rates are rounded to the nearest integer before lookup; missing entries show as “—”.
CustomInitializes from CVT-RB; use Reset Custom from CVT-RB to restore.
BandwidthPeak / line / active bandwidth (Mbit/s) from bits-per-component and color format.
Link fitUse checkboxes to show interface groups (MIPI, DisplayPort, HDMI, etc.); tables below the timing grid show Ok/No and utilization % per column.
ModelineX.org-style modelines appear below the table with one-click copy.

FAQ

Is data uploaded?
No. Everything runs locally in your browser.

Relation to third-party calculators?
CVT math follows the public VESA specification; DMT / CEA data comes from public standards. This site implements its own UI and logic.

EDID workflows?
Use modelines as a reference; for firmware EDID replacement see the MS2130 EDID utility.
