WG Monitor - What is this stuff?

Anyone know what this circuit is for on my monitor?


One pin says +30V and the other says H_SYNC.
It's printed WGM2550-U4GR17J on the chassis.

Is that white wire supposed to be hooked up to anything?
I have an older picture where it looks like the white connector was hooked up to the +30V line.
I think the cats may have knocked some stuff loose on the monitor at some point.

Thanks!

Damnit, just noticed I posted this in the wrong forum...

I have a 25" U500 WG with a similar resistor. In the manual it did not state its purpose, but it did say to switch from one pin to another to effectively enable/disable it, based on the chosen horizontal refresh rate.

I wonder what the worst could happen if I choose poorly.
I remember getting berated in another thread when I plugged it in without knowing if it needed an isolation transformer or not
Luckily this one didn't need one!

According to some googling and that sticker in the first picture it's for switching between 25khz and 15khz mode.
Although some threads I found make it seems there's a little more to it. Who knows!
