I recently moved my desk from one side of my office to the other. I unplugged all cables from my tower and left the cables plugged in on the monitor. When I hooked everything back up, there are now faint horizontal lines scrolling vertically. It's most noticeable on gray or blue screens.
Inspiron 660, Windows 10 Home 64-bit
Monitor is connected via VGA cable.
I've also attached different photos of the line on the screen. The background here is a medium gray. I cannot do a screenshot of it, because it does not show up on a screenshot. Wondering what this is and how to fix. I have just ordered a 2nd monitor since I'll be working from home for awhile, so hoping to figure it out.
Do you have an add-in video card (eg, AMD Radeon) or only onboard Intel HD Graphics? If you have an add-in video card, did you connect the monitor to that add-in card and not to the onboard VGA port?
Since you moved the PC to the other side of the office, it might be connected to an outlet on a different circuit than in its previous location. So is there something else on that circuit which might be causing interference on the power line? Or something in an adjacent room...?

I had checked the outlets as well cause I thought that was the problem, but that was all good.
However, right after I placed the order for my 2nd monitor, I decided to order another one, just in case it was the monitor and it needed replaced. Both of my new monitors came in today and after hooking both up, turns out my original monitor was the problem. I'm not sure what happened in the move (my office space is fairly small), but just glad I have the new ones and no more lines.
After I posted this, I figured it was the monitor because if I took a screen shot, it wouldn't show, but it was visible on the screen. So only made sense that it was something with the monitor itself.
Thank you for your reply and suggestion. Much appreciated!
that is not a personal answer really, it is all ways to fail. a full list. ok. and test. (nice post btw, very very good)
herring bone effects like that can be other light sources bad hitting your screen , some LED lights in a room that use Chopper to control them do that. and worse, RFI noise too. (imported junk lights ) not FCC part B certified. lamps. just turn all room lights off , so easy that, and 1st.
the herring bone pattern can bad PSU , bad caps. after 9 years, the failed, and noise exits PSU to all parts inside.. called chopper noise, SMPS noise, bad.
for any monitor there are 3 forms of noise (assumes monitor fails on 1 PC not 2) if 2, monitor power pack bad.?
optical noise (room lights)
radiated, a.k.a. RFI radio Freq. interference or EMI.
the old monitors are cheap 60Hz only monitors. but not told new monitors . model numbers.?
your old monitor is 9 years old. do you run them 24/7?
here are better monitors.
if the old monitors fail in the dark too the monitor many have a bad DC power supply (caps bad)
to gain a real monitor V_refr, above 60hz you need at least $100 as seen here, clearly.(and Dell is not IT)
