testing. I'd much prefer a 'Disable external display resolution doubling' or 'Always use external display native resolution while in Coherence/Full Screen mode' checkbox.
or perhaps an "Auto (Native Resolution)" option in the 'Scale to fit screen' drop-down.
Just a simple way to turn OFF parallels' attempts to control display/DPI scaling (on all screens, both up and down-scaling), while retaining resolution auto-detection (so the virtual machine display resolution updates when the window is resized or put in Coherence/Full Screen mode)
the 'Keep Ratio' option does not appear to do this in Coherence/Full Screen modes.
