I have the 3 BenQ GW2270 monitors and a Gigabyte Z87-HD3 Intel Z87 Motherboard.

I want to be able to connect all three monitors to a digital port, but my motherboard only has 1 X HDMI, 1 X DVI and 1 X VGA. I notice most of the motherboards and graphics cards I've looked at have three display ports but only 2 are digital. I have them connected to my motherboard using the three different connection types.

How can I get around this, other than spending quite a lot on a new motherboard or high spec graphics card? I only use my PC for general usage and no gaming. The display of these monitors is 1920 X 1080 so nothing intense. The reason for this is so that I have a consistent picture across all three monitors.

Could I get two graphics cards with one or two digital ports on each? Maybe something like this

What about a DMS graphics card which would use this kind of splitter?

Any help would be greatly appreciated.

  • If I may ask, what is the need? What's not good enough with the VGA?

  • The display is much slower to react when turning on compared to the other screens.

There are motherboards that have three digital video outs. For example, the Asus Z97-A has one DisplayPort, HDMI, DVI, and VGA connector, and supports three displays simultaneously.

Alternatively, you could get a graphics card that has three digital outs. Something as cheap as an HD 5750 should fulfill the requirement without requiring any extra power from your PSU. I'd recommend just browsing eBay looking for something in the Radeon HD 5000-7000 series or GeForce 400-700 series.

One final option: you could use an MST hub on an enabled DisplayPort port/GPU/OS to split a single DisplayPort signal into multiple DisplayPort outs and connect each to a given monitor, but because of the high cost of this method, I won't detail it.

You can buy a cheap external videcard with 1 digital Out and then using it together with your integrated motherboard's video. But previously you need to check that your motherboard's BIOS supports this function - you can find extra information there . It works well in Windows 10. I used this way in other case: my external card has only digital outputs, but I need to plug third monitor with VGA input only.

  • AFAIK neither current gen Intel or AMD CPUs support this feature.

  • Not his motherboard or a current gen processor unfortunately, I wouldn't count on this feature.
