Hi, that was my first thought as I have blank dongle connected for remote access, sadly unplugging that makes no difference. Are you on AMD or NVIDIA?

edit: fixed it, turn out to be be something wrong with MADVR, even though MADVR worked in MPC-HC and KODI DS better gui, I reinstalled it from scratch and its now working, I tried that before but used my settings backup, this time I set it all up again from scratch, guessing some sort of registry issue.
