The problem also exists with a Dell DA300z adapter. Please find the output of dmesg
attached where first the Dell DA200 and then the Dell DA300z were connected to the device.

The Dell DA200 works fine on a Dell XPS 13 9370 with Debian’s Linux 6.5.13-1, that means the resolution of 1920x1080 is working. So it seems to be a problem with the Chromebook.

Hi,
I believe 1280x720 is the limitation of the MT8183 chip as I didn't see any higher resolution with my Kukui device. I didn't check the spec before leaving this comment though.

I thought the internal screen has a higher resolution, but it’s 1080 x 675. The
The maximum display resolution is only 2,400 x 1,080 pixels.
So in theory it should be supported.

It seems the display pipeline for the internal display (DSI) has higher clock rate. Also, the resolution support depends on the refresh rate as well, so the claimed 2400x1080 might only work on lower refresh rate.
For the external display, the display modes are mostly rejected by the pre-defined max_clock_khz
in mtk_dpi.c:
Description
Using the Lenovo IdeaPad Duet Chromebook and connecting a Dell DA200 adapter (HDMI, Ethernet, USB) and a 1920x1080 Dell monitor to the adapter using HDMI, only the resolution of 1280x720 is configured, although the adapter also support 1920x1080.
There was a similar problem with Intel devices tracked inhttps://bugs.chromium.org/p/chromium/issues/detail?id=707716 , and correctly fixed in upstream Linux kernel commit 9a86cda07af2 (drm/i915/dp: reduce link M/N parameters) . Though this problem seems different as the higher resolutions are not even shown in the selection list, so do not seem to be detected.
