    Note that HDMI 1.4a/b only supports 4K resolution at 24/25/30 frames per second. This is fine for watching movies, but not for gaming. 4K resolution at 60 frames per second requires the yet to be released HDMI 2.0. Or you could just forget about these patches and use a DisplayPort 1.2 connection. 4K decoding has been supported in Intel's VA-API driver since version 1.0.18.
