Ok, got my system, got the cameras installed, but I am fighting this horizontal scrolling line issue on one of the 6 cameras, the cable is not near any electrical wiring or electrical equipment and there are no florescent lights in the house, I believe that this is a ground loop, but man its kicking my ass. If you can, swap that camera with another working CVI camera of the same model.
Monitor have wavy lines?
If the problem follows the camera then at least we know the issue is not in the cables or the power. If the problem does not follow the camera but stays on the same DVR channel, then we need to look at other possibilities.
In that case, I would look at the power supply. Try to power the problem camera with it's own individual power supply. Also, if the power run is long try to power it locally.
The maximum length of the run with issues is approx ft, there is no where to power the camera locally. That will rule out the DVR and leave something going on with the cabling. Basically change connections on back of DVR. I am am thinking your ground on the connection in question could be bad. Are you using 18 Gauge? Try putting the camera on its own unregulated power supply and use extra amperage. That would point to that channel of the dvr being bad. Personally, I would take an extension cord out to the camera, power it up, and see if it clears up.
Then you'd know if the camera was starved for power. That's like temporarily powering it up locally. What wall wart spec did you try? I would go with 12v 2amp, as opposed to 12v 1 or 12v 1.
You could even try 12v 4 or 5 amp too.In the last couple of days or so perhaps since I got itthe monitor has started flickering. There are lots of horizontal or maybe wavy horizontal-ish lines all over the screen. They give the appearance of moving up or down, or jumping around really fast. I am not sure if they are white or some other light color, but they are most noticeable in against darker backgrounds gray especially. So I was wondering is there a fix for this issue?.
Currently is plugged to a wall outlet, I have tested STFC and I guess because is black background it does not show any lines up. I have tested in other laptop as well and same thing.
LCD Monitor Wavy Lines
I also made sure refresh rate is at 60hz. I'm not sure if the problem is getting worse, or at least more annoying. Since there is no flickering on my laptop's monitor I think it has something to do with WFP monitor. Is there anything I can do to fix this problem? Have you updated the video card driver? Do you have the video resolution set to the monitor optimal of x? Thanks for your reply. I have not yet updated the driver. Is this a Dell driver? Do I have to install an additional driver?
Thanks again. I would first update the laptop Radeon HD driver. Then, load the WFP driver. I've just updated both drivers as you mentioned and still get the same horizontal lines. One of the things I just noticed is that after rebooting my laptop and get back to the desktop again, the lines were little bit less intense, but secs later I got them back with same intensity.
I'm not sure what I should I do next. Browse Community. Turn on suggestions. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

And interference is typically introduced when the source is very near, or when the cable's shielding is damaged, or not grounded properly through the connectors. The first thing to check is to make sure all the cables are securely fastened, on both ends, and not running parallel right next to power cords.
Move speakers, wireless devices, or any large power consumer like a big old CRT monitor with big magnets and transformers inside away from the computer, monitor and cables. Turn off florescence lights and nearby TVs and radios and other electronics.
If the cables are tight, the graphics card if not on-board is secure in it's slot, and you isolated the monitor, speakers and cables as much as possible from potential interference sources and the wavy lines are still there, try the new monitor on another computer.
If you see wavy lines with two computers preferably at different locationssend or take the monitor back.
You got a bad one. If the image is sharp and wavy free on the second computer, then something is wrong with your computer a failing power supply can do this or something in or very nearby your computer room has problems.
Besides a better image than analog, digital is not normally affected by nearby devices spewing out stray radiations. Since we don't have brand and model numbers of either of your monitors, I don't know were your two stand in the mix. So if your new monitor has a DVI or HDMI connection, but your computer does not currently support digital graphics, and you don't do 3D animated gaming, there are plenty of inexpensive digital cards you can install that "hopefully" won't require a larger power supply.
If the ultimate goal is to play the newer 3D animation games, then you should just start the budgeting process for a new power supply and a decent graphics card and maybe more RAM. Community Forum Software by IP.
However my new LCD monitor is very 'snowy', comparable to an analogue tv signal that doesn't quite have the perfect signal, or a VCR quality video.Log in Register. Search titles only. Search Advanced search….
Very odd and troublesome. Any ideas what is causing this and how to resolve? I have noticed this with a number of different monitors I have tried so I do not believe it is hardware related on the monitor side. Last edited: Oct 15, Ok, think I figured it out. My monitor has a default input setting which was set to DVI. It also has an auto-search setting which if it doesn't see DVI it looks for what is plugged in. So, I set default to VGA and turned off the auto-search function and it worked beautifully.
So issue was in monitor, not the SP. Good info for anyone else experiencing the same issue. Crimson Idol 8 New Member. This only usually happens to me when I give the VGA connector an accidental hit, and even then, not all the time. I have no idea what's going with the wavy lines upon connection. Faulty cable, maybe? Stoliguy New Member. It's actually a ground sync error I'd never tell you to remove the third plug from your monitor, or that it would keep it from happening Stoliguy said:.

Wavy lines on extended monitor (weird)...
Rather than removing the 3rd prong - try a 3 prong to 2 prong adapter.Vertical lines running through your computer monitor can be disrupting during use: they can often be removed by properly configuring the computer and making sure the connection doesn't have any problems. Black vertical bars blocking the sides of the screen are an indication of an incorrectly configured graphics card. Colored bars running through the display image are an indication of a bad connection.
Run Windows Update on the computer to make sure the graphics card drivers are up-to-date. Old graphics drivers may not have the proper configuration to support the monitor, which may be remedied in the update.
Right-click on the desktop, choose the "Screen Resolution" option, set the resolution drop menu to the setting that has the " Recommended " text next to it and click "OK. Straighten any bent pins you find in the connection cable. If any pins are missing or damaged the cable should be replaced.
Check for any wear or bends on the cable. The cable might look fine on the outside, but the internal wiring could be damaged. Straighten the cable by pulling any bent sections apart with your hands. Swap the cable with a second cable of the same connection type and check for the vertical lines.
If the lines are gone, the first cable is bad. Connect the computer to another monitor using the second cable. If the monitor still showing the lines there is a problem with the graphics card.
Try using a different video connection port or type if the computer and monitor both support one. If the monitor still shows the line with a different port of the same type, there is likely a problem with the monitor connection. Connect the monitor to another computer using the second cable. If the monitor still shows the vertical lines, there is a problem with the monitor's connection port.
