Raspberry Pi 3可以做4K视频吗？

#1 楼

我能找到的最佳信息表明，可以输出4K分辨率，但帧速率相当可悲。 Pi 3与Pi 2具有相同的GPU，因此信息仍然有效：

我已经成功地在Seiki E50UY04上以15Hz的频率获得了3840 x 2160（4k x 2k），在树莓派的两个发行版上工作...（最新
Wheezy / Openelec）。电视显示它正在接收此分辨率和赫兹电平，并且看起来非常清晰。

这是我的whiezy的config.txt：

# 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

尝试使用Chromecast 4k，您可以从RPi流式传输到Chromecast。
