Hello all, i have LG 42lf5800. I have a question, when i play some video over tv's default app, (ex, youtube), the video is so smooth and nice for eyes, even on the other apps, netflix etc, but over pc cable (HDMI) its not so good, i mean the picture is still sharp, but refresh rate isnt same as i play something over tv. Is there any solution to solve this? I have not so bad graphic card on pc, its ati radeon r9 280x
