樹莓派4 HDMI顯示

樹莓派4直接上電，試過諸多參數，HDMI在我的顯示器上（LG27M35）無法顯示。

但是改電腦USB3.0供電，HDMI工作正常。

相關參數如下：

/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
