Hi
It sounds like a frame rate issue.
For the UK your monitor and graphics card needs to run at 50Hz, typically by default it runs at 60Hz. To get 50 frames into 60 an uneven number of frames have to be duplicated, and this causes a slight judder every second.
You will need to set up a custom profile to get 50Hz, this used to be possible on older drivers, but since Intel has dumbed down everything to a stupid Metro style all white space interface, the customisation options are missing.
Without being able to change your refresh rate to 50Hz you will never be judder free. Other graphics cards will let you make these setting changes, but oddly Intel who market the integrated solution perfect for media what with their QuickSync technology etc, seem to complete ignore that a big chunk of the world needs refresh rates other than 60Hz for judder free playback.
You will probably find most YouTube clips and other video on the internet has no judder, this is because they will all be 30fps or 30Hz which goes evenly into 60Hz.
For Blu-ray you need to set your monitor 24Hz or more precisely 23.976Hz, something that Intel graphics often don't allow or do not do accurately. This means over the course of a film the audio and video can move out of sync.
On a TV via HDMI you have 60Hz, 50Hz, 24Hz all supported and switched to automatically, however on a computer you need to make changes manually based on what you are watching.
Sometimes a TV is the best option for watching films.
Could Intel tell us please on this rubbish new all white graphics property interface how we set custom refreshes, and when will the bug of the monitor not going in to sleep mode be fixed. Or should I send you my extra electricity bill costs because my monitor is on constantly!
Regards
Phil
