Hi there guys. Recently I have been reading and learning a lot about framerates and refresh rates etc just out of my own personal interest. This was mainly driven by the knowledge that BT Sport Ultra HD in the UK is broadcast at 4K but more importantly imo, 50fps progressive. Anyhow, in the UK, tv is broadcast at 50Hz, so 25fps, mostly interlaced. If I am watching say BBC iPlayer, or ITV Player, or All4, or the BT Sport online player on my computer, should I manually change the framerate output of my PC to 50 HZ. I ask this becasue from my understanding, 25fps tv in the uk is shown on tvs by repeating each frame twice to fit the 50Hz refresh rate. If I am watching 25fps content on my 60Hz pc monitor, surely that just isn't right and there is going to be some form of juddering/jerkiness somewhere by the pc trying to perform some from of pulldown? I use a program called KODI for a lot of media, and in the settings of this I have it set to always change the monitor refresh rate to match the content. I feel that this is a mechansim that should be built into all of these online live/catch up to services. However I don't know if I am right or wrong and no amount of googling is helping me decide if I should manually change my refresh rate or not when waching something not via KODI. Thanks in advance, but I have been researching this for so long!
