而且黑屏之发生在HDMI，
VGA就没问题。
咋解决呢？ |

xrandr --output HDMI1 --auto
if HDMI1 does not work, use "xrandr -q" to list all available outputs. |

比如raspberry pi是在/boot/config.txt里设置。 |

looks like HDMI1 is currently your default and only output, which HDMI port
you are trying to activate? if it is HDMI2, you can use
xrandr --output HDMI2 --right-of HDMI1
in fact, the easiest way to do this is to use arandr. just apt-get install
arandr. it has an easy interface to activate/layout displays.

发帖数: 7160 | 8 i only want to output HDMI1, not matter it connects to monitor or TV.
what's the scenario i should execute the "xrandr --output HDMI1"?
by connecting to monitor, or to TV?
if to the TV, when it has the output (then no point to run the command),
or lose the output (then WHERE to run the command)?
Thanks.

your HDMI1 is already activated and output signals. see the "*" next to the
60 in the first line?
are you sure you set the proper HDMI input in your monitor/tv settings?
