The spec sheet at the URL you quote below mentions HDMI 1.4a. Although I can see how they might be skirting the truth about HDMI 1.4 compliance. Are there any GPU's and/or cards that are known to display 4k at 30hz or above under X? -- You are receiving this mail because: You are the assignee for the bug.
