2560x1600 HDMI screen limited to 1920x1200

On an Intel NUC machine with this graphics card:
# lspci|grep -i vga 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)
the highest resolution on screen preferences is 1920x1200 whereas the native resolution is 2560x1600. The display is 'repeated' (tiled) across the full resolution. I do believe that I have run Haiku at full resolution on this hardware, to a confidence of 95% (i.e., it's based on a non-recent memory only).
This may be related to a similar bug that I reported for versions of the Linux kernel beyond 4.9.0: https://bugs.freedesktop.org/show_bug.cgi?id=101245
Summary of that bug: a confusing or nonsensical EDID from the monitor causes the driver to set the wrong resolution.
In the case of Linux however, it is possible to use xrandr commands to set the full resolution, after booting. I don't know if an analogous command exists for Haiku.
