Did I read this right? A VGA input for a 2560x1440 monitor? AND no DisplayPort???? What the hell, Acer.
I still don't understand why VGA is an option on any new device, be it monitor or computer. It needs to die already and make DisplayPort or HDMI standard. If you current device can't hack it, get an adapter or get an upgrade.
The thing with 1440p becoming the standard is that suddenly all the games that you could max out easily on 1080p start to feeling sluggish unless you, dare I say, turn down the settings. Not being able to max something out makes it feel incomplete.
