I just took out Sky Sports on Now TV with boost, im using the built in App on my LG OLED, picture quality seems fine but watching football is really blurry in motion, and the sky sports news ticker judders.
I'm wondering if this is down to the LG app (I know it doesn't support 50 fps), would using a NOW TV stick improve things?
Yep it's mainly down to the current inability of the LG Smart TV's inbuilt NowTV App not being compatible at the moment with the 50fps playback with a NowTV Boost Pass.
You could try playing around with the LG picture processing to mask the 25fps playback, where i would start with True Motion switched off then experiment with the different De Blur & De Judder settings.
Though motion is not the strongest strength with LG brand televisions.
With regards to a NowTV stick then yes with Sky Main Event & Sky Premier League you should see a noticeable improvement with the Boost Pass.
Where the other 9 Sky Sports channels that doesn't currently support 50fps you will see no difference between the LG NowTV App and the NowTV Stick or any other NowTV device that is compatible with the Boost Pass at 50fps.
Yep Sky Sports News channel current frame rate is still 25fps so using a NowTV stick will make no difference with the judder on the moving ticker bar.
Playing around with your television motion picture settings may or may not mask it slightly.
I actually use a NowTV 4K Smart box with the auto adjust refresh rate set to enabled and because the Sky Sports News channel native frame rate is 25fps the ticker information scrolling bar on screen still stutters and the text is a little blurry on my Panasonic mid range 4K television.
Where if there is a simultaneous Sky Sports News Broadcast on Main Event or Premier League the ticker bar text is pin sharp and silky smooth because of the 50fps native frame rate.
