Splitting the screen in Windows 10 helps you work faster, stay organized, and multitask without switching windows again and again. Whether you want to use two apps side by side, a vertical split, a 4-way grid, or even use dual monitors, Windows 10 provides many flexible options.

This guide explains all methods step-by-step, including keyboard shortcuts, Snap Assist, and advanced multi-monitor setups.

⭐ Why Split Screen Helps in Better Productivity

Using a split screen helps you:

• Work on multiple apps simultaneously
• Compare files, documents, or web pages
• Drag-and-drop easily between windows
• Boost productivity (especially on large screens)
• Manage online meetings + notes together
• Edit videos/photos while referencing tutorials
• Improve workflow on 2 monitors or laptops

For multitasking, split screen is one of the most useful built-in features of Windows 10.

Windows 10 comes with Snap Assist, which helps automatically arrange windows side-by-side.

👉 Steps:

1. Open two apps or windows.
2. Drag the first window to the left corner until you see a transparent outline.
3. Drop it — it snaps to the left half of the screen.
4. Windows will show other open apps on the right.
5. Click one to fill the right half.

That’s it — your screen is now perfectly split into two.
