This problem is reported in other forums too [1]. So, according to [1] 60 Hz should work, and it does work under Microsoft Windows. I’ll check the cable first. Please confirm, that you have HD Graphics 530 devices, that drive UHD monitors with 60 Hz under GNU/Linux. [1] https://forum.level1techs.com/t/why-cant-intel-530-graphics-run-4k-60hz/113809 Thanks to tsa in #intel-gfx pointing me to the logs of a Skylake system in the Intel test matrix [1]. There should be some support for UHD with 60 Hz. ``` […] 72 71 connected DP 600x340 32 modes: name refresh (Hz) hdisp hss hse htot vdisp vss vse vtot flags type clock [0] 3840x2160 60 3840 3888 3920 4000 2160 2163 2168 2222 0x9 0x48 533250 […] ``` [1] https://intel-gfx-ci.01.org/hardware/fi-skl-6770hq/testdisplay-i.log Though the system from the test matrix has the device below [1]. ``` 00:02.0 VGA compatible controller [0300]: Intel Corporation Sky Lake Integrated Graphics [8086:193b] (rev 09) ``` [1] https://intel-gfx-ci.01.org/hardware/fi-skl-6770hq/lspci-s02.log Created attachment 135544 [details]
Linux 4.14 message with `drm.debug=0x1e log_buf_len=5M`
It’s not the cable. Testing a DP-to-DP cable shows the same problem.
Please find the Linux messages attached.
Here is also the verbose output of `xrandr`.

Please note, that the datasheet [1] of the monitor claims that 3840 x 2160 with 60 Hz is supported. > In order to display the 3840 x 2160 native resolution, please ensure the graphic card and its drivers used on the PC/Laptop is capable of supporting resolutions up to 3840 x 2160 at 60Hz via DisplayPort connectivity [1] https://partnerdirect.dell.com/sites/channel/Documents/Dell_UltraSharp_32_Monitor_UP3214Q_brochure.pdf Created attachment 135545 [details] Linux 4.14 message with `drm.debug=0x1e log_buf_len=5M` (DP 1.2 in monitor enabled) Ok, Aaron’s answer in the thread *Can't enable 60hz with display (Dell UP2414Q)* for Nvidia gave the right clue. > You have to drive the monitor in MST mode to get 60 Hz. It turns out, that DP 1.2 was disabled in the monitor menu. Now, 60 Hz are detected.
