Does the 5k iMac support 2 external 1440p displays?

    I have 2 x 27" 1440p displays, neither with displayport input. Could I use 2 of the Mini DisplayPort to Dual-Link DVI Adapters to connect to a 5k iMac?

    The Retina iMac can drive up to two 1440p displays at 60 Hz, so it should work just fine.

    Thank you - just got the iMac and connected 2 of the 1440p monitors with the dual-link DVI miniDP adapters and it works perfectly

    Do you have the M290X or M295X? How is the lag, if any, when using various apps?

    I run office and stock trading applications on an i5 retina system with the base GPU. No games or video/photo editing.

    With my use, all 3 displays are very smooth. No lag at all. The other monitors are cheap Korean 27" 2560x1440 displays so I needed to buy the dual-link DVI adapters. I tried various other connections but this was the only one that game me the full resolution.

    I had a PC based system and when that died, I moved to a 2012 i7 Mac mini. Unfortunately that wasn't up to driving 3 displays very well and also ran very hot.

    The iMac runs in the 60s and is perfect for what I need.

    I got this with a 3TB fusion drive and 16gb memory from the refurbished store, which seemed like a good deal, and should last me a while.

    Shame it doesn't support dual 4K monitors at 60Hz. :(
