[quote]I can confirm that the game works correctly with Portrait Eyefinity. I can access all of the HUD elements. See below:
I imagine it is the same reason that Borderlands works fine for you in portrait......
For some reason I would assume all games would work with portrait I see no benefit playing games in portrait.
3 X 24" would only be 1920 X 3600.
It is obvious you would still see more but it does not seem like it would be as amazing as landscape. And the bezels would be even closer together which would really bug me.
Personal Preference I know but I imagine a game would support portrait more so then landscape. And it would make more sense to me to just play on one big screen rather then 3 in portrait. I think Eyefinity only really shines in landscape.
Actually ME1 does not work properly in Portrait Eyefinity as the HUD elements are partially obscured. It's worth noting that ME2 doesn't share the same problem.
I think certain games work particularly well in landscape mode, such as racing and flight sims. Other games lend themselves well to portrait mode. Compared to one big screen, you've got 3x the resolution either way. Portrait is slightly wider, while landscape is obviously much wider.
I had posted a poll on another forum and found that there is a 60/40 split in landscape/portrait preference. It all comes down to personal preference as you say.
