I've been using the DP input on mine, the Microcenter Auria-branded Korean monitor seems to be one of the better ones, at least as far as inputs. The controller only allows refresh rates up to about 75Hz, though, I think I would probably trade away my native DisplayPort for the ability to config 100Hz+ refreshes, if I could. I can actually set and use up to about 120Hz, but it freaks out a little and has a very regular screen corruption when it's above 75Hz.
And CoH2... Yeah, just started that. I'm still nowhere near good at it, but at least I'm doing better than I did at Planetary Annihilation (I want to be less bad at that so very badly).
