We are testing VDI on Server 2012 R2 Datacenter. The guest VM's are all Windows 7 Enterprise. The user's connect tohttps://vdiserver/rdweb. From there, they click on their collection and their manually assigned virtual machine starts. They do NOT use traditional Remote Desktop Connection. This is all done via browser and the RDP plugin.
I have a user who had previously made use of the "make text and other items larger or smaller" option in screen resolution on her regular workstation. However, when connected to her virtual machine, this option is greyed out. I understand that some things just aren't possible in Remote Desktop. But, is this one of them?
