I´ve had problems now for some time.
I get a video playback with very high contrast and very slow moving(lagging picture. This happens in XBMC and BS Player but not in VLC, In VLC the CPU goes up to nearly 100% though so I can´t use it.
Current Graphics driver: 10.18.10.4176
If I reinstall the driver and doesn´t reboot the NUC the picture and playback runs perfectly, but after reboot it´s back to the high contrast. If I change the contrast down the picture looks normal but it´s still very laggy. So at the moment I have to reinstall the driver and not reboot everytime I want to use XBMC.
I also get a warning sometimes on startup with CMOS battery failure if it matters?
Please get back to me if you need additional information.
I will need to replicate this issue but I need some software configuration details:
Which version of Windows do you have?
XBMC version number?
NUC BIOS version?
About the CMOS battery problem, I would say this is not related to the video problem.
