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.
hdmi_force_hotplug=1 sets the Raspbmc to use HDMI mode even if no HDMI monitor is detected. hdmi_drive=2 sets the Raspbmc to normal HDMI mode (Sound will be sent if supported and enabled). Without this line, the Raspbmc would switch to DVI (with no audio) mode by default. Share Improve this answer edited Oct 13 '12 at 2:11 Ashwin Nanjappa 1,305 2
hdmi_drive. Chooses between HDMI and DVI modes. DVI mode will mean that sound is not transmitted though HDMI. Normal mode will transmit sound if supported.
28.12.2016 · With raspi-config or the GUI version set the machine to autologin the pi user to a command line. At the end of pi's .bashrc add the line /home/pi/hdmimodes/trymodes . Inside /home/pi/hdmimodes create modefile with the digit 1 in it (possibly optional). Create a file called prefix which contains hdmi_group=2 hdmi_ignore_edid=0xa5000080
Connect your Raspberry Pi via SSH Open the command terminal on the system Write the line below to open the configuration file in the text editor sudo nano /boot/config.txt Look for the line as stated below in that file.

The Raspberry Pi has up to three audio output modes: HDMI 1 and 2, if present, and a headphone jack. You can switch between these modes at any time. If your HDMI monitor or TV has built-in speakers, the audio can be played over the HDMI cable, but you can switch it to a set of headphones or other speakers plugged into the headphone jack.
30.10.2016 · I want to have the output setup the same when using a DMT HDMI mode (hdmi_drive=2 hdmi_group=2) and when using composite. So would I be correct in assuming that: Code: Select all. sdtv_mode=0 sdtv_aspect=2 ... If I can figure this one out I will be using a Raspberry Pi 3B running RISC OS ...
Sep 30, 2020 · This is read by the GPU before the CPU and Linux are initialised. In Linux systems, this file must be edited as root. Any changes will only take effect after you have rebooted your Raspberry Pi. To set HDMI video resolution options you will add 2 parameters: “hdmi_group” and “hdmi_mode”. These parameters must be appended to the end of config.txt.

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 ...
The Raspberry Pi Zero uses a mini HDMI port, so you will need a mini-HDMI-to-full-size-HDMI lead or adapter. On the Raspberry Pi 4 there are two micro HDMI ports, so you will need either one or two micro-HDMI-to-full-size-HDMI leads or adapters, depending on how many displays you wish to attach.
