Will XPS 9360 capable to 4k output? #123

Closed wanghuangjie closed 5 years ago

First of all, huge thanks to DARKVOID,

i'm using darkvoid's EFI with merely modify(like SN, boot driver name), and it's perfect ,IMHO. but the problem is UHD620 is not capable, or 9360 is not capable for 4k output.

why am i saying this?

when using internal display ,everything work flawless. But when i connect (type-c -> DP ) to 4k monitor(dell u2718q) ,using it for a while, it become lag. FPS drops, cpu increase to 100%,(mainly chrome , kernel_task ,windowserver)

i've try to clean install Mojave, and try with different version CPU FREIND, a usb fan to cooling . Nothing change ,still lag after using it for a while.

wondering is there someone facing the same situation like me? or maybe it's limitation of xps 9360?

Any reply will be appreciated.

progress from idle to full load

Running luxmark,cpu drops down to 0.5Ghz

finally figure out , cpufriend is the key.

CPU AND GPU SHARE SAME POWER.

don't let cpu use too much power ,it will lead gpu short of power, hence gpu will become lag.

The newly added OpenCore loader specifically enabled HDMI 2.0 support, this might resolve your issue. I'll see about enabling it on Cover as well.

Seems like my issues has been solved since vram increase to 2048MB

still laging ,maybe the performance of HD620 just not enough to drive 4k HiDPI in daily use？
