Anyway, my fears seemed confirmed when I logged into Windows for the first time with the S2440L connected. While my screen resolution was correct (1920x1080), there was a large black border around the viewable portion of my screen; the Windows desktop did not fill the whole screen.
I could not find any settings in the monitor's own menu options that made any difference, and changing refresh rates had no positive effects.
I should note that I have an ATI Radeon HD 5700 series graphics card and, and I eventually stumbled across a poorly documented feature of the ATI software that was causing the problem. Here's how to fix it on Windows 7:
- Go to Start > Control Panel > Display.
- Click Adjust Resolution, then click Advanced Settings.
- On the Catalyst Control Center tab, click Catalyst Control Center. After a while, the Catalyst Control Center dialog should appear.
- On the left side of the dialog, click My Digital Flat-Panels, and then click Scaling Options (Digital Flat-Panel).
- On my computer, the Scaling Options slider was set somewhere in the middle. Slide it all the way to the right (the "Overscan" direction), to 0%. You should see an immediate change.
- Click Apply, and then close the Control Center.
