3440x1440 not working

[gdotts]

I have a MSI GTX 1080 TI 11Gb card.  Been playing on it in DCS for over a year on 3440x1440.  Upgraded CPU from AMD 3600 to AMD 5600.  Now when I enter DCS it gives me 2560x1440.... so In options I change it to 3440x1440 and click X upper right corner.  Screen dosen't change so back into options but resolution still says 2560x1440 again.  Over and overI have tried to change resolution...am I missing something?  No OK button on bottom of options seen just X upper corner??  Maybe my 1080TI card is bad?  Please advise thank you!

X usually closes apps without changes - like a Cancel button. Try to edit \saved games\dcs\config\options.lua file, change the width=2560 to 3440 and run again. If it doesn't work, just make a copy and delete the file. DCS will make a new one with default values.

There should be OK button on right side. You can edit config file "C:\Users\%username%\Saved Games\DCS.openbeta\Config\Options.lua" find width and height and change it to your resolution. EDIT: draconus was faster. 

["width"] = 3440

["height"] = 1440

Just hit me.... All I had to do was start DCS "as administrator" and BAM!!  Full screen on a 3440x1440 34 " monitor.  All is good!!    Thanks guys
