I 'borrowed' a picture from King Athelstan from the Lothlórien thread in the DCI:LA test forum. As you can access the Pei Beta, you can have a look there for yourself. Watch the factions symbols, they should be round and they would be, if we used the original Med2 4/3 aspect ratio instead of the 2560/1440 ratio that K.A, and I play on. And the mini map left at the bottom should be (almost) square. If you played on a 1920/1080 screen till now, you must have noticed this also.
The bigger 16/9 ratio screens don't actually show a worse effect, in my experience, they just make the effect more obvious.
Edit, I stumbled on something that looks to be an old 4/3 picture. This should give an idea on how Med2 was supposed to look:
