It looks like the Raspberry Pi 3 may be powerful enough to output 4K video, but I haven't seen anything about it anywhere.

Does anyone know if the Raspberry Pi 3 can output video over HDMI at 4K resolution? If so, is it 30Hz or 60Hz?

The best information I can find suggests that it's possible to output 4K resolutions, but at fairly miserable frame rates. The Pi 3 has the same GPU as the Pi 2, so the information should still be valid:

I have managed to get 3840 x 2160 (4k x 2k) at 15Hz on a Seiki E50UY04 working under two distributions on the Raspberry Pi... (Latest Wheezy/Openelec). The television shows it is receiving this resolution and hertz level, and it looks very crisp.

This is my config.txt for wheezy:

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
overscan_left=-150
overscan_right=-150
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=3840
#framebuffer_height=2160

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=2
hdmi_mode=87

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

# for more options see http://elinux.org/RPi_config.txt

  • It does run the same gpu but at 400 instead of 250mhz

    True. I've yet to see any analysis on what performance impact that might have on 4K frame rates.

  • The 400 vs 250mhz won't affect what HDMI can scan out. HDMI's clocks are independent and also derive from elsewhere in the clock tree.

I think you will be able to play but the frame rate should be very less else choppyness will be there or it might stuck at a frame as well.

Try Chromecast 4k, you can stream from the RPi to Chromecast.

  • This isn't a very complete answer. Is the RPi cable of processing/transmitting that level of bandwidth? Is there a particular service needed to do so?
