so I’ve got a Dell laptop with an i5-7300u. I’ve recently upgraded to a 4k monitor at home that I plan on using for video playback and programming (i have a desktop PC for gaming).

Now, according to Intel’s website and other platforms (youtube guides, web articles, etc), the i5 should be able to handle 4k video, etc. It’s alright with general tasks (I’m writing this on the 4k monitor just now). But as soon as I put youtube on at 1080p/4k the CPU hits 100% and stutters like mad. I’m not sure if this is a Ubuntu issue, browser issue or if my CPU just isn’t meant for 4k despite Intel saying it is.

Any advice would be great, sorry if the post is too long I tried to fit as much information in as I could.

Skylake drivers aren't necessarily included for your iGPU. See: Updated kernel to 4.8 now missing firmware warnings

After these new drivers are loaded you can turn on more Intel iGPU features via grub command line:

GRUB_CMDLINE_LINUX_DEFAULT="noplymouth fastboot acpiphp.disable=1 pcie_aspm=force scsi_mod.use_blk_mq=1 vt.handoff=7 i915.enable_guc_loading=1 i915.enable_guc_submission=1 i915.edp_vswing=2 nopti nospectre_v2 nospec"

Notice the i915. enhancements in my grub command line that take advantage of new drivers downloaded in above link.

@Woddell, if you can provide the service tag, I can check in my DELL EMC Partner portal. DELL usually builds and tests both Windows and Ubuntu on newer machines like yours
