How do I project to a connected screen?

September 5, 2019 updated by Leave a reply »

Is it possible to make the screen of one laptop appear on another laptop? How do you mirror desktop PC to laptop wirelessly? Windows 10 includes a useful feature that lets you turn your Windows 10 PC into a wireless display, so you can mirror another PC’s display with ease. In this tutorial we’ll walk you through the steps to project your screen to another Windows 10 computer through Wi-Fi.

Before getting started, make sure you have two Windows 10 computers that support Miracast, and they are connected to the same Wi-Fi network.

Part 1: Set Up The Receiver Computer

On the computer you want to use as a wireless monitor (which we’ll call it “receiver computer”), press the Windows key + I together to open the Settings app, navigate to System -> Project to This PC. By default the Projecting To This PC feature is turned off. You can turn it on by selecting “Available everywhere“.

If your PC needs to run on battery power only, just turn off the last option labelled “This PC can be discovered for projection only when it is plugged into a power source“. Now, your main computer can cast screen on this computer.

Part 2: Project Your Screen

On the main computer – the one you’re projecting the screen from, press the Windows key + P together. The Project menu will appear as a flyout to the right of your screen. Just click the “Connect to a wireless display” link.

It will take a while to scan around for wireless monitors. Once your receiver computer is found, just click it.

Now, a Connect permission prompt will display on your receiver computer. Go back to the receiver computer and click Yes to allow the connection.

Now, your receiver computer will merely mirror what’s on your main PC’s screen, and you can you can control it with your mouse and keyboard.

Computer projectors are incredibly popular these days. Whether used for showing PowerPoint presentations and business reports during meetings, or movies at a party, projectors add value and convenience to many businesses and homes. Any modern Windows computer can connect to a projector, and the Windows 7 operating system makes set-up a breeze. Before beginning, make sure you have the correct video cable for your device, and dim any lighting in the vicinity of the projector screen to increase visibility.

Step 1

Plug one end of a video cable -- the plug will either be a blue VGA plug or a white DVI, depending on the projector -- into the laptop’s video port.

Step 2

Plug the other end into the projector’s “video in” port. Again, the port will either be blue (VGA) or white (DVI).

Step 3

Turn on the computer and the projector. The projector may need a minute or two to warm up.

Step 4

Click “Start,” and then type “projector” (without the quotation marks) in the search box. Or, press the Windows key and "P," and skip to Step 6. A similar shortcut involves pressing and holding the "Function" (FN) key and your external display function key, which would probably be among the top row of keys. It may have a monitor icon or "LCD/CRT" printed on it.

Step 5

Click “Connect to a projector” when it appears in the list.

Step 6

Click on the display option you want.

Choosing "Duplicate" will project the image onto your projector screen, while also displaying it on the laptop screen. "Extend" allows you to use the projector screen and your laptop in a dual-display configuration. This means that both the laptop and projector screens will combine into one huge display; while "Projector only" will shut off your laptop screen and enable viewing on the projector screen only.

Tips

• If your laptop does not have a VGA or DVI port, it’s still possible to use it with a projector if you have a docking station, port replicator, or USB to VGA/DVI adapter. Similarly, if the projector and laptop have differing video ports -- one has a VGA and the other a DVI -- adapters are widely available and fairly inexpensive.

Warnings

• Projector bulbs get extremely hot during use, so be very careful.
• When you shut down the projector after use, you’ll notice that the unit stays on, and the lamp may remain lit, although dimmed. This is the beginning of a cool-down process, which may last for several minutes. Once completed, the unit will shut off, and may be unplugged. Do not be impatient and unplug the unit during the cool down process, as the (very expensive) bulb may break if you do so.
