树莓派4 HDMI显示

树莓派4直接上电,试过诸多参数,HDMI在我的显示器上(LG27M35)无法显示。

但是改电脑USB3.0供电,HDMI工作正常。

相关参数如下:

/boot/config.txt

# 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=1
hdmi_mode=16


# 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
