When playing at the resolution of1440x900 the HUD is not directly centered on the screen. This issue never occurred until the release of Halo 3 on PC. Shots do not line up either.

Another issue is the season point system user interface is also off-centered as well and cuts off the remaining unlocks at the right-edge of the screen.

Note: The first issue does not affect any other Halo game on the PC.
same issue
Same thing is happening to me. Super weird. It only happens on multiplayer. The only fix i have for it is to go into windowed mode, kinda sucks but works.
Edit: going into windowed only helps a bit, hud is still a bit off center
Exact same problem. I can only get the crosshair to stay centred if I change the resolution to an unplayable resolution where everyone looks super tall and skinny (i.e. tiny horizontal x regular vertical).
It was fine before the update; I guess halo 2 is unplayable until it’s fixed 
Ye same issue, even player tags are to the left of players,
Same for both of these on my end. I’m using a 16:10 aspect ratio.
I’ve submitted bug reports on them, do so as well ^^
Any update? It’s still like this on my end.
