Dell E6530 running fully patched Windows 7 64-bit. The unit has a 1920x1080 panel on it. When docked I also have a Seiki 4K Pro monitor in landscape mode currently. The 4K monitor has a split defined at the 50% up the monitor with separate images on each monitor; three total with the split on the 4K. That's should be all that I tweaked from the default install. Everything works fine with this except when resuming from sleep or hibernation when undocked; no 4K monitor attached. Clean boot works normally, but once the laptop enters a sleep state and is resumed the explorer is completely locked up; even the mouse cursor won't move at all via the trackpad. Keyboard works to some extent, but no explorer related functionality (e.g. Windows key) does not work or is unusable if anything does show as the result of a key. I can launch task manger and a few other things. The only answer appears to be power button for 4 seconds hard shut off. I've let it sit for minutes while tying to revive it. Pretty much locks up the laptop. Clean boot (hard power shut down) resumes normal operation, but next sleep reproduces the issue. Removing only DisplayFusion corrects all the problems with sleep and hibernate. I'm fairly confident that this program is having some issue; and probably with the lack of the missing undocked monitor.

I was hoping to purchase this product (was on trial) since I was planning to use at least one rotated 4K monitor split to make better use of the 4K space. Your product looked and appear to allow my required functionality perfectly, but an issue with undocked stated would definitely be a deal breaker. I use my laptop undocked much of the time. If there is any additional info that I can provide, please let me know. I was running the latest download as for Friday 9/23/2016.

Thanks for your response, but I appear to have jumped the gun with my initial problem source. Your product was not responsible for the issue with coming out of sleep. NVidia's Desktop Manager settings were also enabled (testing grids), and they appear to be the actual source of the desktop lockup when recovering from sleep/hibernation when that is active. I just retested this issue with that functionality shutoff and a reinstalled version of DisplayFusion (and new trial license courtesy of your support as well) and recovery from sleep works fine when undocked and re-docked with 4K attached and split only when docked. Everything is working fine. Sorry to have troubled you about this issue and thanks for the quick reply.
