There was a previous post here - https://www.remoteutilities.com/support/forums/forum1/439-dell-venue-8-pro-5830_-full-control-or-view-only-mode-doesn_t-work-or-sometimes-view-rotate-90-degree-and-very-unstable
We have exactly the same problem. We are using this product to support our customers, and have recently taken to deploying Windows 8 tablets to them. Remote Utilities gives a completely useless, sideways-on, screen display when you try to connect to them. If the tablet is used in the default (0 degrees rotation) mode then it works fine, but we have to lock these to either 90 or 270 degrees to support the application running on the tablet.
[censored] , on the other hand, works perfectly on these tabletss and sdjusts to whicheve angle of rotation the tablet is set to use, displaying it the right way up within the viewer.
This is a major issue as the only reason we purchased Remote Utilities was to enable us to support our customers - we are now looking at having to go and buy [censored] instead to enable us to do what we need.
