Does it have to be "mono" if I had used a cable which was stereo on the 1/8" on one end and stereo on the 1/4" (TRS) end instead of a (TS) mono end could that cause a problem?
I'm far from an "audio expert", so I do a lot of guessing and speculation.
I believe my Monoprice 5" studio monitors came from the same factory that make the M-Audio BX5s.
Might be some minor changes, but in general I think my Monoprice 5" are just rebranded BX5s.
So i bought a cable with the 3.5mm stereo plug on one end and dual 1/4" mono TS plugs on the other end to connect my sound card, and it works.
(Technically it's a short 3.5mm stereo plug going to two RCA connectors adapter, then daisy chained to a RCAs (red/white) to two 1/4" mono plugs cable).
These are the cable and adapter i use to connect my sound card to studio monitors.
I guess you can feed an unbalanced audio signal to the studio monitor, using a mono (TS) 1/4" plug, one channel feeds the signal, the other channel is the return/ground.
Or feed the studio monitor a balanced audio signal using the stereo (TRS) 1/4" plug, two channel to feed the audio signal and the third channel is the return/ground.
I believe sound card (and computer audio in general) uses an unbalanced audio signal.
From my understanding balanced audio is where twice the power (voltage or amps?) is sent, each channel is carrying the same power as a normal mono channel, but your using two channels, so twice the power in total.
So it might be when you send an unbalanced audio signal, but split the power to two channels, each channel is only carrying half the power as it normally would, so the studio monitor might be a little confused on what is being sent to it.
Or your sending the correct power on just one of the channels, but the studio monitor is expecting two channels.
