SAMSUNG QLED TV -Q8C unable to detect 1080p60FPS video(on hdd)

[RudyZ]

So I have a samsung qled tv Q8C its a 4k TV (almost 3years of purchase now) , I can easily play 4k (30fps) content , i recently download some (first time) 1080p 60fps,120fps ,144fps and 4k 60fps videos/animated movies to play it on my TV (through externalHDD) but the TV just do not detect any of these videos though all the other normal (i guess 30fps) videos still shows like earlier. So any workaround those 60fps+ videos can be played on this TV
