He guys,

I'm trying to watch a 4K movie (61 GB file) on my 65 inch 4K TV using my PC. I'm using a HDMI 1.4, but whenever i start the movie, i'm getting massive lags. BSplayer wont even show me an imagine, VLC has massive lags and so does Windows movie player making it impossible to watch a movie. I also noticed that whenever i play the movie, my CPU usage is skyrocketing to 100%. I also have this problem when i'm trying to watch the 4K movie on my monitor using a displayport. ( LG 34UC88-B 34-Inch 21:9 Curved UltraWide). i'm aware that i havent gotten the latest CPU's and GPU's but I really cant imagine my computer isnt strong enough to run a 4K movie.

i5 4670K
AMD r9 290 4 GB
8GB ddr3 ram 1666mhz
Windows 10 OS

Am i missing something here?

4k is surprisingly taxing. We've taken for granted our rigs can handle it due to hardware decoding, but even very fast older CPU/GPU's only dedicated enough silicon to handle 1080p. Couple things you can try. Open VLC preferences, Video, and try enabling or disabling Accelerated Video Output. I believe that determines whether or not VLC tries to use your GPU to decode. I'm not sure whether your GPU hardware or CPU software decode will be faster. Second, go into Input/Codecs, and make sure Hardware-accelerated decoding has been disabled. I believe this one tries to use Integrated decoding, like Intel Quick sync, and Haswell IGP definitely isn't up to it. Finally, you can also set Video quality post-processing level to 0. Technically, you...

Technically, you can try pressing "[" during playback to set the speed down 10%, but the audio slurring may drive you insane.

Also, I think HDMI 1.4 might limit you to 4k@30hz so that could also be an issue with the TV, but not the monitor.
