The computer monitor is not connected with the host, and the power-saving mode is displayed!

My computer is out of order. It's Lenovo's whole set. It's not an assembly machine! Yesterday, I went to the repair shop to do the new XP system (formerly win7)! Yes, it was good to try it out there! After coming back, plug in my monitor, the result shows that after the Lenovo display power-saving mode, and then the black screen! I took the connection to another computer and tried to find out the line was ok! (using other people's lines to plug in, I do not show) and use my computer box inserted other people's monitor, the results proved that the chassis is no problem! Also use other people's box inserted my monitor, and found that the monitor is also good! But using my own box to plug in the monitor is what I mentioned earlier! What should I do?! Which expert can point it out?! The younger brother is very anxious! Wait and answer! Thank you, thank you!

Does your monitor connect with the head of the computer blue or white? The white one is DVI, the blue one is VGA, which is set on the display menu, which accepts the signal type, and the corresponding color is set to the corresponding DVI or VGA.

The display power saving mode is that the monitor cannot find the signal. Some brands have a set of motherboard display, and plug in an independent graphics card, so there are two cards behind the video jack. Generally, when you insert an independent video card, you display the monitor on the display port, so there is no signal, so it saves electricity. The only show is the lower level of the mouth. The vertical view is the upper vertical opening. If this is not the reason, or it may be a problem with the display settings of the system, you should try to adjust the display settings a little lower.

Obviously, your computer monitor, VGA or HDMI line is not plugged into the computer, so that the host signal has not been transmitted to the monitor, the monitor will not signal into the power-saving mode.Also, if you're sure the monitor is plugged in, then there's something wrong with your computer's operating system and it doesn't wake up during sleep, so you should start with reinstall or optimize the os.
