## HDMI mode options

**Note for Raspberry Pi4B users:** Because the Raspberry Pi 4B has two HDMI ports, some HDMI commands can be applied to either port. You can use the syntax `<command>:<port>`, where port is 0 or 1, to specify which port the setting should apply to. If no port is specified, the default is 0. If you specify a port number on a command that does not require a port number, the port is ignored. Further details on the syntax and alternatives mechanisms can be found on the [conditionals page](./conditional.md) in the HDMI section of the documentation.

### hdmi_mode

Together with `hdmi_group`, `hdmi_mode` defines the HDMI output format.
Together with `hdmi_group`, `hdmi_mode` defines the HDMI output format. Format mode numbers are derived from the CTA specification found [here](https://web.archive.org/web/20171201033424/https://standards.cta.tech/kwspub/published_docs/CTA-861-G_FINAL_revised_2017.pdf)

To set a custom display mode not listed here, see [this thread](https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=24679).

Note that not all modes are available on all models.

These values are valid if `hdmi_group=1` (CEA):

In the table above, the modes with a 16:9 aspect ratio are a widescreen variant of a mode which usually has 4:3 aspect ratio. Pixel doubling and quadrupling indicates a higher clock rate, with each pixel repeated two or four times respectively.

Note that there is a [pixel clock limit](https://www.raspberrypi.org/forums/viewtopic.php?f=26&t=20155&p=195443#p195443).The highest supported mode on models prior to the Raspberry Pi 4 is 1920x1200 at 60Hz with reduced blanking, whilst the Raspberry Pi 4 can support up to 4096x2160 (known as 4k) at 60Hz. Also note that if you are using both HDMI ports of the Raspberry Pi 4 for 4k output, then you are limited to 30Hz on both.
