I need to change the second monitor's resolution when I login into an account.

I made a bat file which has a line ChangeScreenResolution.exe /w=1024 /h=768 /d=0 in it. I need it executed at login so whenever I enter a specific account the resolution changes to specified dimensions. I tried using task scheduler and use At Logon as a trigger but it didn't work. It throws 0x2 or 0xC0000005. I allowed the desired account to Log on as batch job in local politics. Another thing is that when I press Execute in the Task Scheduler interface, the task works, the resolution changes. But when I log out and in of the account, it throws errors.

Meanwhile If I choose At Unlock Working Machine, it works fine, I relogin with the desired resolution. I tried specifying paths to the .bat file in Start In property, tried using cmd.exe with the path to the bat as an argument. But with no avail. I require help of my peers because I've spent 6 hours already and my brain slowly deteriorates.

    Have you tried simply putting a shortcut into the startup folder?

  • @SeñorCMasMas I wrote my answer while you posted the comment. I only noticed after I submitted my answer.

  • Also, you don't need a batch file, just run the command. If using the startup folder, you can use a shortcut to ChangeScreenResolution.exe and specify the parameters. If using the task scheduler, you can specify the program directly.

Don't use the At Logon trigger. It runs very early in the logon sequence and it is possible the display isn't properly intialized at that point.
Just place a shortcut to the BAT file in that users Startup folder (c:\Users<userid>\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup)
Make the folder if it doesn't exist yet.

  • Actually, that was the first thing I tried but I considered it a bit slow, so I wanted somenthing more straight-on.

  • There is a reason that it is slower. That startup folder won't get called until everything is initialized that needs to be.

  • got it, thanks. I wish there were settigns for each account so I could just specify what resolution I want at login of a user.

  • By the way, is there a way to hide a popping cmd window when tasks execute? It flashes only for a brief moment but I'd like to hide it for aesthetic reasons.

The thing I did was I used At Logon trigger but delayed the task for 10 secs which is kind of same as putting a bat into the start-up folder. Well, I guess it is what it is.
