Adding 3 monitors on Windows 10

August 14, 2015 11 comments

I’m currently using an HP EliteBook 9470m, and am trying to set up Windows 10 after some problems with my existing Windows 7 installation. Unfortunately, it’s not all plain sailing.

The last issue I just tackled is using more than two monitors. I have three – my main laptop display, and then two 1920×1200 HP monitors that are orientated in portrait mode, and then sat side-by-side.

This is quite a complicated concept, since not only more than two monitors, but one is 90′ rotated, and the other is 270′ rotated. They are also set up in virtual space to match the physical arrangement – if I move my pointer off the top of my laptop screen, it slides onto the bottom of my external screen – which is the left if you turned the screen back to landscape.

To top it off, one is running off Displayport, the other off VGA, off the internal Intel HD Graphics 4000 chip.

It’s weird, but it works

So – once Win10 was installed, naturally it just cloned to one of the two displays, in Landscape. My battle was then to get my setup as it was before, described above.

 

The first issue, is that it only seems to recognise two displays in any of the display settings. The default driver from Windows is 10.18.10.4252, dated 10/07/2015.

Going to the Intel website finds a slightly later driver, v15.33.38.64.4252, dated 27/7/15. Aalthough not certified by Microsoft WHQL, I installed this, rebooted, and then got some recognition of my three displays in the native windows config screen.

Given the same end build number of 4252, I wonder if perhaps it’s the same driver as was installed previously, and changed nothing. I wonder this, because even after the reboot, the main Intel HD Graphics Control Panel only let me use two displays. I could now choose from all three displays – it listed them all – but I could only select any two to be active.

Eventually, I managed to tease Windows into admitting I had three displays. I couldn’t find any way to do this within the (usually more powerful) Intel Control Panel, but did so from the right-click menu on the background, and went for a Clone Display option, choosing both the external displays

I kept juggling with these options, and then in the Control Panel, until I managed to get all three displays lit up at the same time. I was then able to configure each display in turn for orientation and resolution, and finally, position, to get the setup I wanted.

All this was generally much harder than with Windows 7 – mainly because the Intel Command Centre has various screens and options hidden in single panes, making it harder to quickly fire off a flurry of different changes. Doing so in the alternative interface, the native Windows background menu options, would have been laughably awkward to do, having to reopen the menu for each individual change.

Anyway, it all seems to be working so far, so on to the next issue.
