The Windows 8 Snap feature lets you view apps and the desktop side by side. To use the feature you need a monitor with 1366 x 768 resolution or better. What if you have a smaller monitor with less resolution? All it takes is a quick registry tweak and you’re good to go.
Note: There’s a limit on how low of a resolution display you can use. To use Windows 8 apps at all, you need a minimum of 1024 x 768.
Whenever you mess with the registry — in any Windows version — it pays to be extra prudent. Be careful to follow the steps slowly and carefully. As always, back up the registry first.
To open the Registry Editor, use the keyboard shortcut Windows Key + R and type: regedit and click OK.
Or from the Start screen type: regedit and click the regedit icon under results.
When the User Account Control window comes up, click Yes.
Now, navigate to:
Right click on ImmersiveShell. Click on New >> Key.
For the new Key value, type: AppPositioner and hit Enter.
Highlight AppPositioner and in the right panel. Right click and select New >> DWORD (32-bit) Value.
Now type: AlwayEnableLSSnapping and hit Enter.
Next, right click AlwaysEnableLSSnapping and select Modify.
The Edit DWORD (32-bit) Value windows will display. Change the Value Data from 0 to 1 and click OK.
Here’s how it will look.
Close out of the Registry Editor and restart your computer.
Now you’ll be able to use the Windows 8 Snap feature on the lower resolution display.
Play around and experiment. Move your two screens around so you have the perfect view into your apps.
