Laptop external display flash screen

I used Shenzhou A460P-i7G D2 notebook, always think that the display is a little small, so I bought a Samsung s19c200 LCD, but after the display, when the display shows that some colors, some stripes are beating (that is, the legendary flash screen), but most of the interface display is normal, maybe my eyes cannot see it.

Searching on the Internet to find such problems is still quite common and there are many methods:

1. Considering that there is interference with the vgaine, the problem is not solved after the change.

2. The problem was caused by a display problem. When a flash screen disappears from a friend's desktop or laptop, the display was okay.

3. If there is a problem with my laptop graphics card chip, you can change it to several hundred, and the display on my laptop does not flash, so I think there is no problem with the laptop graphics card chip.

4. Due to unstable voltage, the notebook and display are mutually disturbed. Therefore, the power supply of the notebook is unplugged, and the problem of the pop-up screen is obviously improved, but there is still a little ripple. It is recommended that the display and notebook should not be inserted in the same plug-in board or power supply outlet. Due to environmental restrictions, I have never tried it.

5. Try other video output interfaces. The laptop has an HDMI interface, but my monitor only has a VGA interface. So I bought a video line from HDMI to VGA on the Internet, after the device is connected, the display flash disappears completely, which is much better than pulling out the notebook power, and the display is clearer (maybe it's an illusion ).

Although VGA-> DVI-> HDMI is the development trend on the internet, it seems that you have to support HDMI to buy a monitor in the future.
