I think there must be. I have used a Dell with built-in graphics which required an adaptor to output to two DVI (I think it was) sockets.

I've spotted a motherboard that has both VGA and DVI (or HDMI, I don't remember) outputs. Is it reasonable to expect that both ports can be used simultaneously?

No, it is not. In the past I came across several boards that could only use one at a time, expecially when the choice was between DVI and HDMI. You will have to consult the manufacturer's website and/or the mainboards manual.

lucmove,

Here is a much cheaper dual DVI-D graphics card at $21.55:

Alternatively, the Zotac GeForce GT610 could be just what you are looking for:

It costs $50, is fanless, has positive feedback and is Linux-friendly.

Feedback extract:

Purchased this card as an add-on to my primary Linux desktop. My primary drivers for getting this card were:
* It was fanless & thus quieter.
* It supports 2 DVI ports (I have some older monitors with only DVI, and I didn't want to purchase new cabling)
* Most Nvidia cards are decently supported via the open-source drivers (and I don't need the whiz-bang features).

I wouldn't consider the powersave options of a videocard to be a whiz-bang feature, but to each its own. If performance doesn't matter and the proprietary driver is not a must I would always go for a cheap AMD card, preferably pre-GCN, like the HD5450 or HD6450.

TobiSGD,

If you read my post correctly you will see that I was quoting feedback from an Amazon.com customer.

I did not make those comments myself.

Not true. My Gigabyte GA-F2A88X-D3H mobo has 3 ports - DVI, HDMI, VGA and i can use 3 monitors on it (tested) with onboard Radeon HD 8570D graphics (which is pre-GCN despite its name) from a A8-6500 APU. With the open source drivers (which work very well btw, better that intels drivers on the mobile I7s i have seen).

gradinaruvasile,

I stand corrected.

Thank you for that information.

I have reasonable experience with Matrox graphics cards - I've been able to connnect at least 2 devices at 1200 x 960 display resolution... though there are some resolutions that completely screw up. I am using fedora 21 on a core 2 duo E8400 Intel processor with 4GB RAM (soon to be 8GB) from 7 years back.

Couldn't tell you which motherboard to use though, if you wanted integrated graphics with multiple monitor support.

My laptop is an Intel i5 dual core with hyperthreading and it supports two monitors too - though the external monitor has a limit on the resolution (it's LCD displays at 1600 x 900) to about 1280 x 1024 (or something around there).

- 6th -

But keep in mind that some low end igps(especially intels low end) might not be able to support more than 2 monitors. Also check the mobo specs as TobiSGD said since they do the actual wiring.

For example my mobo has a triple monitor logo on it and the APU too is labeled to be able to do 5760x1200 (3x1920) resolution over multiple displays.

Whatever you decide on, don't forget to google "problems with" plus the name of the product plus optionally the name of the software you want to run on it. For motherboards, also add the word BIOS or Uefi.
