Mac screen resolution

Mac screen resolution

Hi,

Has anyone else noticed that switching to Fit to Screen doesn't work when remotely accessing a Mac?  The  image of the host screen remains small - and text is not readable.

Host is a 27" iMac. Remote workstations have been Mac or PC. In the past, the screen information could be increased/magnified by clicking Fit to Screen - but it has stopped working when the host is Mac.

Any suggestions on making this work again?  I've uninstalled and downloaded & re-installed the unattended access software. I've even adjust the iMac screen resolution (not desirable) without any luck.

Thank you!
Al
