I currently have 2 Dell U2713HM monitors and am looking into buying a Benq BL2411PT for use in portrait mode.
There is a problem, however. My GPU has 4 connections: DVI-D DVI-I HDMI DisplayPort
My U2713HM monitors can only use DVI-D and DisplayPort (DVI-I is incompatible with them and HDMI only allows 1920x1080 instead of the native resolution), which means only the HDMI and DVI-I port are left to use.
The Benq monitor only seems to support VGA (lol), DVI-D and Displayport, so I'm sort of out of connectivity options... so...
