Recently had my monitor repaired after it stopped displaying on it's analog input. After I got it back, it no longer displays it's optimum resolution of 1600x900. Prior to the repair, it worked fine.
As of right now, I've tried the following to fix the issue:
-Updated graphics drivers
-Installed and updated monitor drivers
-Creating a custom resolution in the graphics card setting.
Funny thing is, if I force it to 1600x900 using the graphics card settings, the monitor settings says it's displaying at 1400x1050. Monitor settings are all on defaults (which they were at when they worked).
