Hi, Hope anyone can help me out with this one! Been browsing the net for hours without any result so far.. I´ve connected my Macbook Pro 2.4 GHz Intel Core 2 Duo 4GB ram (Mid2010) to my new Sony Bravia KDL-40EX700 via a Mini DisplayPort to HDMI adapter. The connection apparently works fine giving full 1080p image and sound via the HDMI cable. However. When trying to play back any video in full screen, the playback goes slightly choppy (stutters). The audio is playing back fine. The video is not far from perfect, but the slight stuttering is very annoying! Regardless of what video I play (DVD from MAC, full 1080p files, divx) this issue occurs. When connecting my Xbox360 or DVD/Bluray player via HDMI the picture is smooth. So far I´ve tried the following without any results: run all updates for OSX different HDMI cabels tried various resolutions (1080p / 1080i / 720p etc) changing the modes on the TV (auto, zoom, panorama etc) switching to the TV as main monitor i OSX display preferences running TV as only monitor different settings regarding the Hz disabling various settings on the TV (Sony Motionflow etc) If anyone has the same problem or can point me in the right direction that would be highly appreciated! Thanks!
