(I know this is usually not considered good practice and you may get some switched mode power supply interference. If you can run the mains cable close to the video cable it will reduce the cross-sectional area of the loop and that may help too.
A temporary extension lead should be good enough to give an indication. This should eliminate any ground potential differences. However, electronic devices always have different potentials as the connections get complicated.

Something that may be worth a try is to power the PC and projector from the same socket. Hear 'coil whine' coming out your speakers Or perhaps the dreaded 60Hz hum In this video I discuss a few of the ground loop isolation solutions I tried, an. What Causes the Hums What is a Ground Loop In an ideal electrical system, the ground potentials between the devices are zero. Ground loops cause problems because of either a) a difference in ground voltages between the signal source and destination or b) because of induced currents in the loop due to EM interference. What kind of lights? Fluorescent, incandescent, dimmers, etc.

Get a short male-female cable to hack and install it at the projector end. The screen is usually left connected at the transmit end and disconnected at the receive end so that may be worth a try. InstallGear Ground Loop Noise Isolator, Amplifier Noise Filter for Car Audio & Home Stereo, FeedbacBuy From Amazon. That approach is common in audio and industrial sensor signals for the reasons you've identified. I'm also not super keen to "experiment"if I might damage something, and also re-soldering the vga cables is fiddly work. I don't want to degrade my image quality, or risk damage. Is it possible to disconnect the ground signals inside the VGA cable to eliminate the ground loop without making it unsafe/losing the picture entirely? (pins 5-8, pin 10?) What would be the consequences of doing so? but does seem to indicate that the ground loop is the cause of the horizontal flicker/bars. I disconnected the safety ground inside the projector plug and the horizontal bars on the image went away, but I believe this is not a long term safe option. I've tried hooking them to the same power socket which didn't eliminate the horizontal bars on the projector image.
I'm trying to eliminate ground loop between PC and projector via a VGA cable. All the outlets in my room still cause the mic to create that staticy buzzing.Our hall has a projector hooked up to a PC via a VGA cable but we're seeing horizontal bars on the projector image when we turn on the lights in the hall. I dont know much about anything regarding ground loops, which i think might be the cause of the problem.
The sound was gone, but when I move it back up the sound is back. I was thinking it had something to do with electricity but I know nothing about that, please help!! On reddit, I did what u/patriotbarrow told me to do and moved it to my brothers setup downstairs. Video Ground Loop Isolator is designed to reduce Ground Loop Interference with CCTV signals and can be easily installed in a new or existing systems. Also, the buzzing is there when I mute the mic using the little thing attached to the headset, and using OBS, I can see that the buzzing is still there when the mic is unplugged. JABINCO Ground Loop Noise Isolator,for Car Audio/Home Stereo System with 3.

I even used a USB mic and it still is making that horrendous noise, no clue as to what it could be now. BESIGN Ground Loop Noise Isolator for Car Audio/Home Stereo System with 3.5mm Audio Cable 5,549 999 List: 12.99 FREE delivery on 25 shipped by Amazon. These loops pick up interference signals from the environment. Thus induction coils are formed, usually of one turn only. I'm sure how you can understand how this is completely unusable. GROUND LOOPS By definition, ground loops bring about unwanted currents flowing through two or more signal return paths. Isolate one of the ground paths with an isolation transformer, common mode choke, optical coupler, balanced circuitry, or frequency selective grounding. If I use RealTek Noise Suppression and Discord Noice Suppression and talk really loud at the same time, it sounds slightly bearable. The ground loop can be eliminated in one of two ways: Remove one of the ground paths, thus converting the system to a single point ground. The sound is not coming from my PC and I know for a fact it isnt the mic. Ground Loop Isolator for Video Isolator& Balun Equipment Cctv Camera Accessories. I attached a file as to what it sounds like. Please help this is the most frustrating thing in the world.
I took apart the PC, made sure the audio cables were all connected, restarted, and uninstalled and reinstalled Realtek Audio Drivers. said first filter weight W, and said second filter weight We are GROUND - LOOP. My mic is making a buzzing noise, I know it is not the mic because its really clear on other computers. ( d ) calculating a first filter weight W, and a second filter weight.
