If the video source has only vga... get a vga cable? The less you have in the path in terms of adapters/connectors the better. Cable quality is important but any reasonably well made one will do. Personally I'd be more focused on screening etc. as from my own (limited) experience gold connectors on vga likely don't make a deal of difference... Maybe with dvdi, hdmi it might may make a difference but can't say for sure.

LCD monitors shouldn't make any sound at all, not the slightest. The only thing that is likely to make a noise is a fan and I have never seen a fan inside a monitor.

Unless you are referring to noise in the electrical sense.

In that case you have no choice but to get a monitor with a digital input. To get the digital signal from the 650 Ti it has first got to be turned to analogue for the VGA and then once it is into the monitor is is turned back to digital for the LCD. Two conversation stages from DtoA and then AtoD is bound to lead to signal degradation.

not sound noise
its actually unwanted lines that appear due to bit signal degradation
as of cable tv

I'd be inclined to check the cable quality; and the actual connections - the f-connector plug(s). Can you borrow another screen to test the connections and signal quality incoming - can be either lcd/led or even an olde glass box (crt set)?

What type cable are you now using? Are you using any adapters at either end?

Are you using an extra long cable? I have never had an issue with any standard VGA cable that came with any monitor.

If a VGA cable does it have a bulge in the cable close to the end like the cable I am linking below?

i am using a 2m vga cable
at the end of cable it is a bit tilted due to strain
also sometimes managing cable (from where its tilted) removes noise sometimes
