Windows 7: Wavy Lines Moving On Monitor

Wavy Lines Moving On Monitor

I have desperately been trying to fix this for 2 whole days, and haven't had any progress. I've literally read around 50 threads on how to fix this, and have had 0 luck.


I don't know if it's drivers, or the monitor, or something different. I only see the lines when windows is running (I do not see the lines in BIOS). The lines somewhat change when I change the refresh rate, however they always come back (and they're always there no matter how small, or large the lines are - they differ).


(It is sorta like a fuzz, but they're lines moving everywhere)
(If I put my desktop background as a darker gray, the lines sorta look darker purple if you pay close attention)


I have provided an image, that hopefully will help you find the solution: http://i47.tinypic.com/161ghep.jpg

(the image is taken from a cell phone because I wasn't sure if the lines would show if I took a screenshot, seeing that I do not know the problem)


I have also provided an image which shows my specifications of my computer: http://i46.tinypic.com/20hm2yp.png



Any help would be greatly appreciated.
Thank you

Hello,

There are a few things you can try for this.

1) Update your graphics driver (Drivers - Download NVIDIA Drivers)
2) Change the power cable connecting to your monitor.
3) Change the power socket your monitor is connecting too.
4) Change the VGA/DVI cable conencting to your PC
5) Re-seat the graphics card
6) Check your fans in your PC. The temps could be better - The fans just may have excess dust on them.

Hope that helps

In addition to Dave's suggestions, I have to ask......

Has this just happened, have you changed anything e.g. added speakers close to the monitor ? it does look like some kind of electromagnetic interference (that's why I mentioned the speakers) - is there another monitor you can try ? have you gone through the manual and checked none of the settings have changed or look wrong ?

Just trying to give you some ideas.

Good luck.

Hi.

I see you set the refresh rate @70Hz. Try 60Hz or 56Hz if available.
Who knows it works

Just my two cents

What kind of monitor have you got, and what interface does it use? Magnetic interference only affects CRT monitors, not LCD/LED ones. A CRT monitor is likely to be connected by a VGA lead, whereas LCD/LED ones could use either VGA or DVI (some can accept HDMI).

If you connecting your monitor via a VGA connection, is the whole cable VGA? In other words, does it plug into the graphics card either through a VGA socket or a DVI-VGA adapter? There are DVI-VGA cables available, but the one that I tried gave poor results. Much better with an adapter and an ordinary VGA cable.

If your monitor is either LCD/LED, then it could be that you have set the refresh rate too high. These types of monitors are best run at their native resolution and refresh rates. Trying to run them outside the recommended limits can cause them to fail or display screen artifacts (which is what you're seeing). The fact that you state that the image is OK in the BIOS, but not in Windows would seem to reflect this fact.

What happens if you select Enable Low Resolution Video here? Advanced Boot Options

You can also try Base video in the Boot tab of System Configuration (msconfig.exe).

Tried each one, sadly I still have the issue.

Neither work. Btw, I have an LCD monitor.

Thanks for your concern everyone, I really do appreciate it.

Any other possible solutions?
If you need any information at all, I will gladly post it.

Wavy Lines Moving On Monitor

ddbillsfan: were you ever able to get this issue resolved? If so, what ultimately did the trick? I'm having the same problem with a monitor I received yesterday.

Thanks

Monitor: Viewsonic VP2365-LED 23-Inch Wide e-IPS LED Monitor
Notebook: ASUS N71JQ Core i7-720QM 1.6GHz Laptop 1GB ATI HD5730 Graphics
connected via VGA cable that came with the monitor (laptop has no DVI connection)

Any help would be greatly appreciated.
