[QUOTE="davidf, post: 1153324, member: 19484"] Ideally you want to match the refresh rate of your TV to the fps of your video file. MP uses Dynamic Refresh Rate to determine the fps in the video you are about to play and asks windows to change the refresh rate to match (via the configuration in Mediaportal where you tell it what refresh rate to use for the fps in the video file). You don't want to force any particular rate, but as you generally watch PAL (25 fps material) then the default should be 50hz. Whenever you are about to play any video in Mediaportal it will check the fps in the video against the table you fill in in configuration and change the refresh rate appropriately (MP asks windows and windows asks the Nvidia drivers). Any multiple of the desired rate is fine - although for PAL use 50 or 100 if available as pal is actually 50fps with alternate lines (go to the video configuration in windows and press advanced and it will have a list of all supported rates -use that to fill in the configuration in Mediaportal to get the best combinations. mm has given you the wiki link with the details). When you play a video file in windows it just uses the refresh rate which is in place it doesn't try to match to source... NVidia just provide the drivers, so has no say in the matter - as you say it just knows it's a display which supports certain refresh rates and nothing about the video file playing. If you are using an HDMI lead check in the display properties which refresh rates are supported - PC input tends to be different. You just need to fill in the Dynamic Refresh Rate section of Mediaportal Configuration with frequencies your TV supports and are very close to the possible values (all of which are in the configuration).
