What is "Hybrid Graphics Enhanced Display Feature" in ProBook BIOS?

[BorekB]

My ultimate goal is to disable the dedicated GPU card on my ProBook 650 as the Intel GPU is more than enough for my needs, however, I cannot find any such option in the BIOS. I've came across an option called:

"Hybrid Graphics Enhanced Display Feature"

which is turned on by default. What id does? The help text is "Enable option is to have a visible image on an attached display" which I find terrible and don't understand at all.

Hi BorekB,

I am sorry, but to get your issue more exposure, I would suggest posting it in the commercial forums, since your Probook is a commercial product. You can do this at Commercial/ Notebook - HP ProBook, EliteBook, Compaq, Slate/Tablet PC, Armada, LTE
The support page for your product may be helpful in the meantime:  HP ProBook 650 G1 Notebook PC

I hope this helps.

I went looking for this too, for my EliteBook 840 G1, and found this:

Hybrid Graphics Enhanced Display Feature

Enable additional display capability to allow pre-OS applications to be visible on any one of the available display at boot.

When disabled, pre-OS applications can only be visible on certain displays (Internal Panel, VGA, System Display Port on selected platforms) at boot. Digital displays attached to dock will not support pre-OS applications.

Still dont have a clue what that means though 😄

See below.  Whitepaper is for Zbook but the same principle apply here.

Special note on hybrid graphics during Pre-OS environment
With hybrid graphics on HP ZBooks, HP is using displays that may be connected to either one or both GPUs. Because the standard industry support for Pre-OS session involves only one GPU, there is a standard industry limitation where only displays connected to the integrated GPU may be used during Pre-OS. As such, display(s) attached to the discrete GPU are not viewable during Pre-OS. For example, if users boot with the panel closed and an external display attached to a DisplayPort connector driven by the discrete GPU, that display cannot show any image during Pre-OS session such as during POST, when in BIOS setup, when running early diagnosis, when using Power-On Password, and so on.

HP has implemented special support to resolve this limitation. On HP ZBooks with hybrid graphics, any one display whether it is connected to the integrated or discrete GPU is usable (viewable) during Pre-OS. This feature is called Hybrid Graphics Enhanced Display” and is by default enabled in BIOS. Users may disable this feature to only support Pre-OS session with integrated GPU displays (which is typically limited to the internal Panel and VGA).
