You can run into a situation where the supported resolution for that monitor is not displayed when its only shown as generic VGA. Installing the correct Video card driver is part of it. Knowing what the monitor is, is another piece of the puzzle. The device ID tells Windows what it is. It can then, like you say, lock out unsupported resolutions. It is very rare these days to need the inf file for a monitor. And as you say, many manufacturers do not supply one. My I-Inc monitors just show up as Generic PnP monitors and there is no inf file for them. Windows still knows that 1280 x 1024 is the correct resolution though. It got that info from the monitor. It went through the video card but Windows still knows it. Anyway, this debate is pointless as far helping the OP get dual monitors working. I am now going to go back to my original question.
Why was it so difficult to install the 64 bit version? How did you do the install of 64 bit 8.1?
Yep, that's how I understand it to work. Good post.
So I guess if we ignore how a TV works with full functionality as a monitor without device drivers then it is okay to assume our belief in OSs communicating with monitors via "monitor drivers" is how it really is.
And I guess since monitor makers typically don't provide Linux drivers, the millions of Linux users using widescreen monitors only think their systems are working properly.
Oh, that's right. They are provided by nVIDIA and AMD.
Sorry, but I give.
Thanks Itaregid for your suggestions. I have looked at the Display Fusion website and I will try that out shortly when I reboot from Linux Mint into Windows 8.1. Hopefully that will solve the problem for me. If not I will let you know.
The link to Guided help - setting up dual monitors does not help me as Windows does not see 2 monitors. Both of them show as monitor 1. There is no "Multiple Displays dropdown list" and Win+P tells me that I can't do anything because I am not connected to a second monitor.
alphanumeric you asked "Why was it so difficult? How did you do the install of 64 bit 8.1?"
That is a long story. I will try to summarise it for you.
We bought Windows 8 via TAFE when my wife was studying and we got it for a significant discount. We did not get any CD or DVD or ISO. The link given to us performed the upgrade to XP. Since XP was a 32 bit system on my computer, Windows 8 installed itself as a 32bit system. When I contacted Microsoft and asked about trying to get it to be 64 bit I was told that if I had Windows 7 installed on my computer as a 64bit install, then the Win 8 upgrade would be 64bit. When I asked if they could give me an ISO for 64 bit they said that there wasn't one. So it wasn't even possible to go to a 64 bit computer running windows 7 at work and download the file. I tried it and on XP it was still going to do the 32bit install.
All was running well until I had a problem with my main hard drive. (That is another long story). The computer would boot but was taking ages - it felt like 10 minutes. This was happening regardless of whether I was booting into Linux or Windows 8.1. So I bought a new hard drive and installed Windows XP on it in a partition set up for Windows. I put on SP3 and ran the motherboard install CD drivers so that I had internet access, sound etc etc.
Then I tried to do the upgrade to Windows 8 as I had done before using the link we had got when we bought Windows 8 through the TAFE. It would not work. The websites said that XP was not supported anymore. Another issue was the browser was IE6 and couldn't display web pages correctly. Firefox did not help either. Finally I got on to a support chat with a Microsoft guy and we talked back and forth for nearly an hour while I tried all the things that he suggested. Most of the things I tried led to the same place which started to download and got to 44% (I think from memory) and after 2 hours had not gone any further. He kept telling me that such and such a link would work with Windows XP with SP3. And I kept telling him that it didn't work when I tried it.
I think this link was
Create installation media for Windows 8.1 - Windows Help
I asked him if there was an ISO I could be given and he said no. He persevered and so I kept trying what he told me but nonthing worked. Eventually he gave me a link which downloaded fine (but only after I booted up the computer on the old hard drive into Windows 8.1). I got an ISO (3.5GB) and I then tried to burn it to a DVD with windows 8.1 but that failed. So I installed a 3rd party burner which could burn at a slower speed and I burnt a good copy of the ISO. When I used the ISO to install Windows 8, it ignored XP and put the 64bit version on because it recognised that my computer is 64bit.
I am not sure now which URL I used in the end. The second of these I believe. But I had to do it from my old hard drive running Windows 8. It would not work from XP.

Upgrading Windows with only a product key - Windows Help
The support guy told me that I could borrow a Windows 7 or 8 install DVD and use my code so long as it was "retail or pro".
Tried Display Fusion but no good. My system just will not accept that I have 2 monitors plugged in. It shows the same display on both and calls them both display 1.
I am wondering if I have to replace my motherboard just to keep Windows happy - or put up with only 1 monitor for Windows.
In the future, you should be able to do this, Clean Install with Windows 8 Upgrade , and skip having to install an OS to upgrade from. I'm assuming you have an upgrade key that won't let you do a clean install. Doing the above will let you clean install the 64 bit version of Windows 8.1 with the install media you downloaded from here, Create installation media for Windows 8.1 - Windows Help. The media creation tool will create bootable install media for you by the way. I do all my installs from USB thumb drives. Quick and easy.
Getting back to your dual display issue. have you installed the appropriate Windows 8.1 video card driver for your video card? Video card driver, not the monitor driver. What is your video card by the way?
I just use the onboard video. The Motherboard is a GA 880GA-UD3H.
I have no idea what the video driver is.
Windows says the Display Adapter is Microsoft Basic Display Adapter.
I ran Driver Booster (free) and it says my system is up to date.
Maybe I need to buy a graphics card.
It worked before. It's not working now because you need to install the driver for the video card, GPU. Go here, GIGABYTE - Motherboard - Socket AM3 - GA-880GA-UD3H (rev. 2.0) select support and downloads, then select your OS in the drop down. Windows 8 64 bit. Then download and install the chip-set driver. That should have the driver for the onboard video in it.
alphanumeric is right. Windows is using its own native drivers is uses so you can see what you are doing before the specific device drivers are loaded. You need to install the drivers your motherboard's graphic solution via the link he provided.Windows says the Display Adapter is Microsoft Basic Display Adapter
I thought I had already done that. I had downloaded the drivers for revision 2.2
GIGABYTE - Motherboard - Socket AM3 - GA-880GA-UD3H (rev. 2.2)
Which is called "motherboard_driver_amd_chipset_win8"
So if it did not install when I told it to then maybe I don't know how to intall it.
