4K Video Playback

Post by mmTalish33 on Wed May 04, 2016 4:49 am

I have Dell XPS L502x(Sandy Bridge) with 16GB RAM. But while playing 4K video my machine becomes sluggish.
Any help?
Regards

4K video needs a very fast CPU. Certainly when it is HEVC video. How high is the CPU usage during playback? Your laptop is probably just not fast enough.

CPU usage remains below 23% during playback. But while playing in full-screen after 2 to 2:50 mins playback suddenly goes above 45% and laptop goes sluggish and starts to freeze.
But if i reduce MPC-HC size as shown in the image below it plays smoothly till the end.

Go to the power settings in the Windows Control Panel and set it to "High Performance".

Does the laptop have both Intel and NVIDIA GPU? Then right-click on mpc-hc64_nvo.exe and choose the desired GPU. Try the Intel one first.

It can also be named mpc-hc64.exe

Can you copy this information here? Then I can see which driver versions you have.

Here is a tool to monitor your GPU:
https://www.techpowerup.com/gpuz/

Use it during playback and check if you see anything change at the moment at which the video problem occurs. For example a different clockspeed.
