I have been working with a client on this and have not been able to get it to work.
They have a MS Surface (Brand new one and old one), an MS Surface dock and 2 external 27″ monitors. When we select to only use the 2 external monitors each icon takes about 1/4 of the screen and everything is massively zoomed in.
He is using version 2006 on the new and 5.4.3 on the old.
Is there anything with his setup that could be causing this?
