HW Transcoding does not use P2000 GPU

General Discussions
1

Hopefully this is the right place for this.
Intel i5 Gen 4 3 GHz
Win 10
NVidia P2000
Plex Pass

CPU basically always pegged at 100% when transcoding.
Dashboard does not show (hw) ever

BIOS

  • iGPU enabled
  • GPU as primary

I’ve tried uninstalling and reinstalling latest Plex.
I’ve tried uninstalling and reinstalling latest Nvidia drivers.
I’ve tried unchecking :“Use HW encoding” rebooting. Checking it and rebooting. Still no dice.

Please help!

Attached are the logs.

is there a monitor (or hdmi dummy plug) plugged into the pk2?

are you using remote desktop without the above?

are you running pms as normal, logged in, user (not a service) ?

If any of those answers = no, then
a) use a hdmi dummy plug or a real monitor
b) don’t use remote desktop
c) don’t try to run plex as a service

if none of those apply, try disabling the IGPU in the bios, and/or make sure p2k is configured as the primary display device (in windows display properties).

It looks like it is using NVDEC for decode, but can’t use NVENC due to a driver problem:
