This is so frustrating, i wonder whats the difference between our setups, i just tried 5040 * 1050 with bezel correction and the same issues for me, vendor menus and any other menu draws outside of the screens, did you change anything in your config files? anything at all? so desperate :(
How are you setting the resolution? via config files or using the Mass Effect 3 Config Utility?? For me I dont see the triple screen resolutions listed in game, do they show up for you?
Is the resolution in game set to the same as your desktop resolution?
Last night I messed around with it some more, enabled bezel compensation and set the in game res to 6024x1080, which worked fine. However, when I changed my desktop resolution back to 5760x1080 and forgot to change the in game res from 6024x1080, it broke really badly and did what your describing.
Try setting your desktop res to 5760x1200, then set the in game resolution to 5760x1200.
EDIT: Actually, relevant question; are you using an Nvidia or AMD card?
Skripka: Ok, so the cracked version and the retail version work exactly the same on Eyefinity. My game looks the same as those pics and I'm running 5760x1080 with the retail Origin client. The whole game pretty much runs perfect straight out of the box on Eyefinity. The only thing that isn't perfect from a multi-monitor perspective is the in game HUD (ammo count, powers quickbar, etc.) is not centred on the middle monitor. The only other thing that isn't perfect from a PC gaming perspective is the lack of a native FOV adjustment.
It sounds like there are significantly more issues running the game with NV Surround.
I don't know the finer details of how the game is graded for the detailed report, but I do agree it should probably be higher than a C for Eyefinity systems at least. Even a side note in the comments about better support in Eyefinity would probably be worthwhile.
