I have a QHD display. I have enabled VirtualBox Guest Additions. It works fine, desktop is shown in native resolution. However as usual, everything is too small on it. if I change the scale-factor in host’s VirtualBox, then chars are fuzzy. In Windows and in Ubuntu there are ways to use DPI scaling. I have checked at System settings / Hardware / Display and monitor, but I can’t find this setting there. I have checked Higher Screen Resolution without VirtualBox Guest Additions, but it is for without GA.
Can I somehow change the DPI scaling within WS, if Guest Additions are enabled?
