suggest you use a DVI parrot or similar to spoof the monitor EDID

i dont believe DHTG are limited to 2560 - depends on how you connect to it-
this might be a mini display port bandwidth limit - not the DHTG
The DHTG digital edition gets its signal in VGA. They are connected with minidp to VGA adapter from Apple. I think the ATI does not go beyond 2560 on analog video.
The DHTG digital edition works fine with micro tiles.
I might have to look in the DVI Parrot to see if I get this working with the DP edition.
