关掉一会儿再开，就打不开了，听到开关里连着两声，指示灯熄灭。
正常开是一声，指示灯点亮。此时唯一的方法是拔了HDMI线，把电视
打开，再连上，就又好了。研究了电视机说明书和网上，找不出这是
什么原因。以前用同一根HDMI电缆连DVD机没这问题。
这是什么原因呢？我想是哪里的设置问题但找不出来。 |

发帖数: 281 | 9 It seems that your card automatically shuts down the HDMI port when it can't detect any powered on HDMI device
Go to AVsforum or Nvidia forum to see anyone there can help you to walk
around it. |

发帖数: 3370 | 12 问题是，如果显卡把HDMI信号掐了，电视机为什么打不开了呢？我把电缆
拔下来就可以打开了。
't detect any powered on HDMI device

发帖数: 281 | 13 After you unplug the HDMI cable, the handshake authorization
process is reset.
You can try to find out what 2 blinks means for your TV. That can give you a clue.
I have experienced similar issue. I usually power off everything at the
same time but the computer always takes longer than the TV to shut down.
That will also lead me to your issue. Now, I always switch to a component
input before I turn off the TV. It seems that solves the issue in my case.
I suggest you go to AVSforum to post the i |

考虑到当电脑显示关闭或关机或者睡眠时，HDMI不输出信号，此时
电视机的开关不受影响，所以下了个小程序，可以设置键盘上的快捷
键来启动它，让它关闭显示输出，这样就可以打开电视机了。;) 考虑到
键盘鼠标容易碰到引起误操作，所以同时锁定屏幕。这样在电脑开机下载
时要打开电视机，只要按这个快捷键然后开电视即可。
这个小程序正好符合要求：
