Randomly changing resolution

[RedBoy]

I've been having an issue since 1.0 dropped with my resolution.
I used to run my game on 3440 x 1440 resolution before the update and it was fine.

But since the update the game would automatically force a weird resolution of 1936 x 1119
and would open on the left corner of my screen.
While 2 cycles of pressing alt enter work there are two issues.

1.After I press alt enter twice to get to my normal resolution the game locks it self in 30 fps
even though the limit is 144

2. After something changes I joing the game or I leave a server it defaults back to the 1936 x 1119 resolution.

Has anyone encountered this problem before? and is there a way to fix this?
(P.S. I tried deleting my config files to see if maybe something got messed up with the config after the update, but that didn't do much)

I am also encountering this issue, when I restart my computer it seems to fix it. Did you ever figure out a solution?

I have found the potential short term solution and probably the cause of the issue.

Playing around with the Scale setting in windows display I noticed that the resolution of Arma Reforger would change. In windows display settings I changed the resolution to 1920x1080 at 100% and Arma would display at 1920x1080. I changed it to 2560x1440 at 100% and Arma would launch at 3860x2160 for some reason, but then at 150% scale Arma displayed at 2560x1440. So I guess play around with those scale settings until you are able to get Arma to display at your desired resolution.

Alright, more long term solution time.

Locate the file Armareforgersteam.exe by right clicking Arma Reforger in your steam library then click Properties>Installed Files>Browse

Right click the Armareforgersteam.exe file and go to Properties>Compatibility>Change High DPI Settings

Click the box under "High DPI Scaling Override" and set the scaling override to be performed by the application.

This should fix the issue and the game will now launch at whatever resolution you have set in windows/nvidia/amd without applying the scaling.
