As the title says the GRID demo and full game work in TripleHead ... sort of ...
First you need to set the Aspect Ratio in the game to "Normal" ...
The menus are vert- with TripleHead resolutions ...which means a lot of what you need to see is off screen ... :(
For instance ... the select key/icon here below the image ...
There are many other things off screen in TripleHead depending on the menu ... :(
The in game views are fine ... but the HUD is behind the gaps between the screens.
What I did was learn all the menus, buttons, keys and made my profile with the game at 1280x1024 ...
Then changed the game back to 3840x1024 ... which requires a restart ... :roll:
It is a bit of a muddle to get through I know but the racing is awesome ... I love it ... :mrgreen:
EDIT ... added a second menu screenshot.
Edit #2 ... added the blue bit of text.
