Thanks for the bug report.
Please clarify:
* which monitor you mean
* what is the expected resolution?
* what resolution do you see instead?
Also the current/preferred information in Xrandr.txt seems to be incomplete so please run:
xrandr > xrandr2.txt
while the resolution is wrong, and attach the resulting text file here.
