In case anyone else has had similar problems, it appears to be an issue with portrait eyefinity in the v14.x drivers. Reverting to v13.12 works like a champ.
There is a thread about the issue on the AMD Forums, so it's not just me. So no upgrading drivers for a while until AMD gets it...
So I see my options as:
1. Do nothing. Stay on v13.12 indefinitely.
2. Install the BIOS update for the card, uninstall v13.12 and install v14.4.
It's really just a risk tolerance question, right? I've read online that people have had problems with Asus's R9 290X bios update, but I haven't...
But it also failed often before eyefinity. With v14.4 and v14.7 I struggled to even get the three monitors enabled in Windows at the same time. And disabling monitors down to just one active was impossible -- I never succeeded at that. After finagling Windows for 20-30 min to enable three...
I agree that it's somewhat unbelievable.
The monitors have a native resolution of 1920x1080. Yes, they were each tested individually with D-SUB, HDMI, and DP connections. They do not have a native DVI connector.

So I figured it out!
My Asus R9 290 doesn't support the most recent drivers from AMD (v14.4), nor the beta drivers (v14.7) nor the drivers on Asus' website!
However, one driver generation back (v13.12) works perfectly. WTF, right?
The only thing I can think of is that there is a...
I just had one more idea: The driver listed on the Asus website for the video card is not as new as the one on the AMD website. Tonight I'm going to try going to the driver from Asus and see if that resolves the issue.
It's a bit of a long-shot, but I'm running low on ideas.
There are no drivers on Asus' website for the monitor (VN279QL). They just have a "MultiFrame" utility to let you show multiple screens in a 4-corners pattern, which is not something I need.
The weirdness continues. With the fresh Windows install I got three monitors in portrait as an...
Tried the 14.7 beta drivers. Still no good.
Wiped the HDD and reinstalled windows 8.1. Still has the same problems.
I'm an stumped and frankly out of options. I cannot get bezel compensation to work correctly, and it can't be a Windows problem because it's a fresh install. But other...
