Spanning vs. Switching Remote Monitors: How to Choose

Choose a combined view for comparing information across screens; choose switching for reading and operating one screen at a time. A combined view is useful only if you can still read the details you need without continually zooming or panning.

Here, “combined view” means showing several remote monitors together in one viewing area. Switching means selecting one remote monitor at a time. Splashtop’s documentation illustrates both choices: select an individual monitor or display all monitors in one window. Availability depends on the product, subscription and client.

Be careful with the word “span.” Microsoft’s Remote Desktop Connection uses /span for a specific mode that spreads a single desktop across local monitors of the same resolution arranged horizontally. Its /multimon option instead matches the session’s monitor layout to the client-side configuration. Those controls concern local displays; they are not interchangeable with selecting an existing home PC monitor in a screen-sharing viewer.

Your home PC might have two large monitors while the device in front of you has one laptop screen. Reproducing the whole home desktop in that smaller area can preserve its arrangement while making individual windows inconvenient to use.

Consider a simple geometry example: two 1920 × 1080 remote displays arranged side by side form a 3840 × 1080 image. Fitting that image proportionally into a 1920-pixel-wide viewing area halves its displayed width and height. Each monitor occupies roughly 960 × 540 pixels, before allowing for viewer controls. That can work as an overview, but it leaves much less room for reading spreadsheet cells or selecting small buttons.

Use your smallest necessary text as the deciding detail. Can you read a cell value, distinguish punctuation in code and click the intended control at your normal viewing distance? If not, switch to one monitor or give each remote monitor more local space.

Also distinguish fitting from resizing. AnyDesk documents original-size viewing with scrolling, proportional shrinking and stretching that may distort the aspect ratio. Check which mode is active before deciding that a monitor layout is unusable. [AnyDesk’s display settings](https://support.anydesk.com/display)

Comparing a spreadsheet with a reference document: start with both monitors visible. Keep the combined view if you can read the relevant entries on each. If you need to enlarge either side repeatedly, try placing the two required windows together on one remote monitor instead.

Writing, coding or editing a detailed document: start with one remote monitor. Switch to the reference screen when needed. If each sentence or edit requires another switch, simultaneous visibility deserves another try, ideally with more local display space.

Checking a download or render: a combined overview may be sufficient when you only need to see whether progress continues. Switch to the relevant display to inspect an error or operate a small control.

Moving a window between remote displays: temporarily use a combined view if available so you can see the starting point and destination. Return to a single display for detailed work.

These are starting recommendations, not measured productivity findings. The practical question is whether hiding the other monitor interrupts your next action more than shrinking both monitors does.

If two remote monitors must remain readable at once, look for a way to open each in its own local window. Put one window on each local display. This can preserve simultaneous visibility without squeezing the entire remote desktop into one laptop-sized area.

This capability is product-specific. AnyDesk documents numbered monitor controls and viewing different remote displays through separate AnyDesk windows. Splashtop also documents a multi-window mode for viewing individual remote monitors on local displays. These examples establish possible arrangements, not support in every remote viewer. Check the requirements for your particular client and subscription.

Keep a local display available for local applications if your task needs them. For example, you might prefer one remote monitor beside a local reference document over filling both local displays with the home PC.

Identify the home PC’s displays rather than assuming monitor 1 is on the left. Windows provides Settings > System > Display > Identify to show display numbers. You can also drag displays into position in Display settings, apply the arrangement and test pointer movement.

Keep two maps in mind: the home PC’s Windows display arrangement and the way your viewer presents those displays locally. Treat monitor selection as a viewing control; check host settings separately if you intend to rearrange the desktop.

For a portrait monitor beside a landscape monitor, inspect whether a combined view leaves either screen too small. A tall reference page and a wide editing window may be easier to use separately. Prefer viewer selection or zoom before changing the home PC’s orientation.

Windows Duplicate displays repeats the same content, while Extend provides desktop space across displays. Changing the host to Duplicate changes the workspace rather than simply changing your remote view.

If an application seems to be waiting for something you cannot see, inspect each remote monitor before clicking repeatedly. A dialog on another display is one possibility to check. A temporary combined overview can help locate it.

Automatic following can also explain unexpected view changes. AnyDesk documents options that follow the remote cursor or the focused window. If your selected monitor keeps changing, check for equivalent settings in your viewer. Use automatic following when it helps you locate the active work; choose manual selection when a stable reference view matters more.

Before typing after a switch, click the intended application and confirm where input will go. Seeing a monitor and having the intended window focused are separate checks.

Use a representative task: compare two figures, edit a paragraph while consulting a reference, or move a window and open its settings. Try it with all necessary monitors visible, then with individual monitor selection.

Notice three things: whether you can read comfortably, whether you lose track of windows or the pointer, and whether you repeatedly switch or pan just to finish the next step. Choose the arrangement that removes the obstacle you encounter most often. This is a suggested personal usability check; no product testing is claimed here.

Keep the choice flexible. A combined overview can help you find a window, while switching can make that window easier to operate. You do not need one mode for every part of a session. Verify the controls available in your actual viewer before planning around them.
