I have been attempting to setup a DN2820FYK with an older tv with a resolution of 1366x768@50hz, this resolution does not show up in the list. So i have been trying to add it with the CustomModeApp.exe utility (in windows/system32/) however when trying to start the utility, the process starts and run's for around 3-5 seconds and then terminates without error. There are no event log's or error messages of any kind.
This is on a fresh install of windows 8.1 Pro, with only drivers, XBMC and Chrome installed.
Graphics driver version: 10.18.10.3383
CustomModeApp.exe version: 8.15.10.3383
