Installed a new 1030 today (replacing a 750 ti) and now I don't get any video when playing 4K HDR.  Was working fine with the old card (not counting the terrible stuttering since the 750 ti can't decode HEVC) but now only the audio plays while the screen remains black no matter how long I let it run.  Then when I stop playback, the video I'm playing will flash on for just a split second before exiting, resolution zooms to 800x600, and HDR won't disengage until I reboot.  Have tried with both 385.41 drivers and updating to 390.77 and have reinstalled DSPlayer also but still no luck.  Meanwhile the same files play perfectly in MPC-BE including HDR disengaging after playback even with the new drivers (I'm on Win7 which is why I had rolled back to 385.41 in the first place).  

Anyone have any ideas?
