Windows 7: Vibrating colors

02 Mar 2018   #1

Windows 7 64bit
Vibrating colors

I noticed the problem a week ago but i thought i am just seeing this but when i logged into a forum of one community and it has a gray background, i noticed the problem is actually still here

The issue is that the color seems to "vibrate" , as in, it seems to be very small wave like and it is showing signs of "white noise" but VERY minimal. i tried recording it but it's not showing up since like i said it's a small amount.
All my drivers are updated and both my monitors are connected via an active adapter that makes the DP and HDMI signals into VGA for both my monitors.
is my monitor the problem? maybe the GPU? maybe the adapter even ?

Start moving things around and swapping things, one thing at a time, to see if you can isolate the cause of the problem. Here are some possible causes:
  • The monitor's video cable could be bad.
  • The port that the monitor is plugged into could be bad.
  • The monitor itself could be bad.
  • The video driver could have a bug; try an older driver.
  • The video card could be bad.
  • The active adapter (converts to VGA) could be bad.
  • The A/C adapter for the active adapter could be bad.
  • If the active adapter draws power from the USB line, perhaps it isn't getting enough power. Try plugging in the USB wire to a powered USB hub or to an A/C to USB power adapter that puts out sufficient power. (1.0 isn't enough; go with 2.1 or more.)
In my opinion, the most likely cause of this issue is your active adapter. Any time you convert video from one format to another, particularly from hi-res DP or HDMI to lo-res VGA, there are potential problems. It could be as simple as the adapter not getting enough power via its USB power line. Or maybe the active adapter is poor quality and is just now starting to fail.

I have a video converter which receives an HDMI signal and converts it to composite video (red-white-yellow), so that I can plug my old TV into the HDMI port on my laptop and watch Netflix videos on the TV. It is powered via a USB line - I guess they are expecting me to plug it into a USB port on the laptop to power the device. But sometimes the onboard USB ports don't provide enough power, so I went to the store and bought an A/C adapter which has a USB port on it, so that I could plug the wire into there. It works fine. But if there was ever a problem, I would first suspect the video converter, because it has never impressed me as being a quality device. But so far, so good...
