# Video connectors

4 video connectors, with what each one actually specifies.

| Name | Millimetres | Inches | Notes |
| --- | --- | --- | --- |
| HDMI 2.1 | 48 Gbit/s — 4K at 120 Hz, 8K at 60 Hz | — | 48 Gbit/s at full capability, but the label alone guarantees nothing. |
| HDMI 2.0 | 18 Gbit/s — 4K at 60 Hz | — | 4K at 60 Hz. The practical minimum for a 4K desktop. |
| DisplayPort 1.4 | 32.4 Gbit/s — 4K at 120 Hz with compression | — | 4K at 120 Hz using display stream compression. |
| HDMI 1.4 | 10.2 Gbit/s — 1080p at 120 Hz or 4K at 30 Hz | — | 4K but only at 30 Hz, which is why it feels wrong for desktop use. |
