Open-Source Linux Driver Support For 4K Monitors

[tomato]

Why do 4K monitors/outputs have to be treated specially? I would have thought it simple came down to mode setting in the driver.

The 4k resolutions need support for newest standards (Display Port 1.2), so you need to know that the hardware supports it or you may be running it in an out of spec configuration.

"but for Intel hardware I believe there is also 4K monitor support in their latest DRM code."

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 use a DisplayPort 1.2 connection.
