Kodi on my Sony Bravia

Installed Kodi on my Sony Bravia TV via Google Playstore. I thought I’d give it a try as it could mean getting rid of my dedicated Kodi box (Acer RL70). I’m hardwired into my network so contention isn’t an issue however I noticed that when streaming my HD movies to the TV – the quality just isn’t as good as what is is when using my Acer machine. I noticed a fair bit of ‘ghosting’ if that’s the correct term to use. Is this something that can be tweaked, or is it just not recommended to use my Bravia as my Kodi machine?
