My laptop external display watertight unplug the power adapter is gone But the notebook can not always use the battery is right I see you on the Internet that is there is a full-featured changes within the 3C option but I can not find the Please help me look very grateful.
If the original adapter is already aging, the filter is not good, for one.
I feel you this is not the problem of ccc, because ccc can only control the video card, if it is caused by the graphics card, nothing more than the following situations: 1. Vertical synchronization, but you have a watermark, certainly not this, then only Is the display refresh rate, the general LCD 50hz, 59hz, 60hz, 75hz, in the desktop properties can be adjusted, generally adjusted to 50hz or 60hz, if it is 75hz, then there will be some watermark display. Ccc Lane can also be transferred, the desktop is more convenient, do not know what you are the system, it is difficult to say

If the notebook and external display have HDMI interface, you can try to use HDMI cable to connect, so you can eliminate water ripples. Because the HDMI interface is transmitted through the digital signal, anti-interference ability.
If there is no HDMI interface, then this problem is not a good way to solve.
