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.

| Item | Description |
|---|---|
| Preset resolution / refresh | Two dropdowns; refresh options depend on the selected resolution; choose None (manual) to edit numeric fields directly. |
| Visible columns | Use checkboxes to show or hide CVT, CVT-RB, CVT-RBv2, CEA-861, DMT, and Custom. |
| DMT / CEA-861 | Refresh rates are rounded to the nearest integer before lookup; missing entries show as “—”. |
| Custom | Initializes from CVT-RB; use Reset Custom from CVT-RB to restore. |
| Bandwidth | Peak / line / active bandwidth (Mbit/s) from bits-per-component and color format. |
| Link fit | Use checkboxes to show interface groups (MIPI, DisplayPort, HDMI, etc.); tables below the timing grid show Ok/No and utilization % per column. |
| Modeline | X.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.
