I bought this monitor and to my dismay, my mac is stretching the resolution to fit the screen. I understand that this is due to the HDMI's inability to display over 1920x1200. I've read about other people's workarounds using adapters for MBP's on here but haven't read anything about the limitations of an old mac with this particular card. Can I do anything with this setup or should I buy a new monitor or a new video card? Also, keep in mind that eventually I would like to run two of these as a dual screen setup for a DAW. Thanks in advance!!!
