<pre>The modelines you're trying to use exceed the capabilities of the poor SKL.
[ 16.182265] [drm:intel_hdmi_compute_config [i915]] unsupported HDMI clock,
rejecting mode
[ 16.182532] [drm:drm_mode_debug_printmodeline [drm]] Modeline 0:"" 0 312250
2560 2752 3024 3488 1440 1443 1448 1493 0x0 0x6
The maximum dotclock you can use is 300 MHz, whereas this mode is ~312 MHz.
You should try the mode that the display reports in its EDID:
241.5 2560 2608 2640 2720 1440 1443 1448 1481 +hsync -vsync</pre>
