Having some issues adding a third monitor to my setup. Had dual monitors but added a video card to add another. Have two monitors on a splitter and connected to the card and the other hooked up with vga.

My computer is recognizing the two monitors connected to the new card, but not reading the onboard device (third monitor).

When I right click the desktop>resolution>detect it finds nothing. Just the two monitors.

Driver issue? Ideas?

I went into the BIOS because I figured there'd be a setting the run the graphics card with the onboard devices. Could not locate such a setting.

Thanks for any input.

You may possibly need an ACTIVE adapter for the third monitor, and have it hooked up to the card.

What card is it?

I could be 100% wrong on this but I thought the card overrules the hookup to the motherboard.

I seen to recall having to hook both monitors to my card when I originally set up my dual system.

My current card supports 3 so I run all 3 monitors from my card.

You can hook up a display to the integrated graphics and the video card, but if its hooked up to the iGPU then you don't get any benefit from the video card

If over 2 monitors, I would ditch your monitors and get a 4k tv running HDMI 2.0.
The screen real estate is incredible and it has 2 cables.
We set one up in the office yesterday and now we are looking at converting our other multi-monitor setups.

Stick to the issue.


OP, definitely need to know the hardware we're working with. Intel did not always allow iGPU and dedicated GPU to work at the same time. I'd specifically like to know the motherboard (or model number of the PC if it's a prebuilt).

Nope. I did this but 2+ monitors is vastly superior.
