Is it recommended to turn on integrated graphics when you have an external one?


Good afternoon everybody, I'm here to ask said question as I own a Intel Core i7 4790 but my integrated graphics are turned off so I want to know if I turn it on my processor performance will decay? I don't want low performance thats why I'm asking this here. I really hope a moderator can guide me, thanks in advance

Recommended is not the correct word.   If your bios allows both integrated and discrete, and you need the integrated in addition to the discrete, then go for it.

TBH I don't know if I need the integrated one. What I know is that my graphic card is working at its maximun (90%) according to the task manager. I'm running 2 games, World of Warcraft and Ragnarok Online. What do you recommend me? Thanks for answering me though

When wanting to go in the BIOS settings of any MB, doesn't this need integrated graphics only?   


I think it does not use external graphic cards at all when going into the BIOS setting screen.

Hello @Jotaperuano

Thank you for posting on the Intel® communities.

We would like to inform you that due to the Intel® HD Graphics 4600 and Intel® Core™ i7-4790 Processor have been discontinued, Intel Customer Service no longer supports inquiries for it, but perhaps fellow community members have the knowledge to jump in and help. You may also find the Discontinued Products website helpful to address your request.

Please keep in mind that this thread will no longer be monitored by Intel. Thank you for your understanding. 

Best regards,

Actually, @Browser-ice, BIOS Setup appears on whatever is the primary monitor. If this is connected to an add-in graphics card, then it uses the add-in graphics card's graphics engine (dGFX). If this monitor is connected to a motherboard connector supporting the integrated graphics solution, than the Integrated graphics engine (iGFX) is used. In some cases, a reflection of the BIOS Setup screen may appear on secondary monitors. In this case, if monitors are connected to both graphics engines, then both graphics engines will be used.

If you need the iGFX engine running in order to support background activities - transcoding for audio streaming, for example, then you might want to have it enabled even if there are no monitors connected to it. If you have no activities like this to support and you have no need to enable it to support additional monitors, then letting it be automatically disabled is just fine. 

It is important to point out that the enabling of the iGFX engine will have no bearing on your gaming. Most games can only support a single graphics engine and having a second graphics engine available does not help at all with the first engine's loading.

Hope this helps,
