Same issue here, samsung UE55UH6900. spent hrs on samsung and microsoft support. by the sounds of it its an issue with MS and they need to issue a fix for it. Appalling they havent all this time (i just bought my SP3)
A support staff i spoke to today, sent me a link for a display drivers hotfix (updating them to "10.18.14.4080.", you may
check your display drivers version in device manager, select display device, right click properties, driver tab and note the version)
However the problem still persists.
Has anyone managed to fix this or had a solution from MS support that worked?
this cant be an isolated issue!!
