Ah, panel arrived today so have quickly set it up. Only shows 180hz but there's an overclock option (still only shows 180hz after turning that on) but that should be plenty enough. Monitor arm is a no-go, need more spacers but have just set up on the stand for now.
Any recommendations on colour settings or where best to set them? Everything looks a little 'off' by default (although that could be due to having an 'off' monitor for such a long time and that becoming the norm).
