I have an ASRock Z97 Pro4 m/b with the on-board video and an i7-4790K 4GHz CPU. I'm running Xubuntu 14.04.4 on it with all the latest updates and the 15.10 kernel (4.2.0-35). i'm wondering if this combination can support a 4k monitor resolution with a 4k TV as a monitor. Does anyone here know? Thanks. MR
