I can't get my monitor to run in 4096x2160.

The highest available resolution listed in control panel is 3840x2160:

control panel

Same when listing "all modes" from the graphics adapter properties in hardware manager:

graphics properties

Monitor is LG 31MU97-B - the resolution is supported and the OSD keeps reminding me the recommended resolution is, indeed, 4096x2160 :)

  • updating drivers didn't add the desired mode even though the inf file lists it
  • tried w/ "generic PnP monitor" as well

Connected to Surface 4 Pro i7

  • the resolution is listed as supported
  • tried connecting w/ DP directly and through the dock
  • tried w/ "extend" and "external only" modes

I've tried adding a custom resolution w/ CRU, but that doesn't seem to be available on 4096px width (note the disabled "OK" button below)

NB: this monitor has been used at 4096x2160 resolution (same cable)

I believe that the problem is with the Iris Graphics 540 card.

It seems that displays can only be connected to it using DisplayPort 1.2 / eDP 1.3 which maxes out at 3840 x 2160 @ 60 Hz, or using HDMI limited to the older version 1.4a which also maxes out at 3840 x 2160 @ 30 Hz.

You might try to use the less-limited HDMI 2.0 by adding a DisplayPort converter that supports it. Such converters may be bought in stores or on Internet shopping websites.

Or if possible for your computer, add/replace the video card.
(Edit: The last sentence was written before I knew the post was about the Surface Pro.)
