Monitor static lines

[anonymous890]

So here is my build
LGA1155
i7-2600
4GB ram 1333mhz
gtx 1050 Ti MSI gaming x with 6 pin
PSU silverstone 500W strider essential

Everything went perfectly fine yesterday, I did get static lines but on the last step that I did, monitor to AVR, system unit directly to the plug cause my PSU is a branded one and I don't want to plug the system uni to the AVR first cause my AVR is a cheap one to summarized it.
Monitor - plugged to cheap AVR
System Unit - NOT plugged to cheap AVR and it's directly plugged.

Now, with the same set-up, when I turned it on, it got static lines, so I transferred the system unit to the AVR, I still got static lines, so I got back to the previous set-up that I did yesterday and it worked, IDK why, what is happening? I haven't got an AVR servo motor yet, no budget for it yet, what was the problem?

BTW:
AVR plugged to another extension

also system unit plugged to another extension (extension that you can put three like metal plugs on, because my power supply has 3 metal plugs and I can't plug it to the first extension that only has 2 plugs and that I don't have an adaptor yet).

What about signal cable GPU > Monitor ?

Signal cable? what is it? well IDK what's that but I'll just add infos, I'm using a DVI-D connector both to the video card and monitor.

Yes, that cable. Try another one, some have ferite at one or both ends, it has function to stop electromagnetic interference.

So I won't use DVI-D? what can you recommend? I only have DVI-D and VGA plug on to the monitor, and DVI-D with HDMI plugs on to the video card.

Just try with another DVI-D cable but also adapter for HDMI could make problems.

Ehh alright, may I ask though? is there a switch on an AVR servo motor? cause if there is, then do I need to turn the switch on my PSU too cause it has switch cause its silverstone 500W strider essential. Meaning switch on AVR servo motor, and also the PSU connected to the AVR servo motor?

Which AVR ?
