My Mac Mini (late 2012) Server model (16GB) is connected to an LG34UM95 widescreen display using a Thunderbolt cable. The resolution is 3440 x 1440 but at 50 Hz. This type Mac Mini is capable of supporting 2 Thunderbolt displays (daisychaining) according to Apple support. Does somebody know if it would be possible to support 2 LG 34UM95 displays using Thunderbolt cables (daisychaining), or would it be too hard on the Intel HD Graphics 4000?
