Broken / Cracked Laptop Screen - use a External Monitor

How to Attach Broken or faulty Screen Laptop to an External Monitor ?

If you having a broken, faulty, or may be a no display problematic laptop by your side then it’s important to connect your laptop to some external monitor to check all the necessary function or hardware is working properly or not.

This is  a useful tip to get you through a typical scenario of dropping your laptop and breaking the screen:



It’s easy to connect your laptop to an external monitor as long as your laptop isn’t broken from the inside:

That means as long as your laptop boot up nicely and gives you the perfect start up sound like, windows opening sound or system boot up beeps etc. that does clarify your laptop is works properly

Almost all laptops can connect to an external display and have the laptop display sent to that external display instead of, or in addition to, the laptop screen. Examples of an external display include a CRT monitor, flat panel display, projector, or TV.

Connect the external display to the laptop's external video connection on the back of the computer. An example of a VGA connector for a computer monitor and VGA port on a laptop is shown to the right. Once connected, your laptop may automatically switch to the new external display, or you may be required to press one or more keys on the keyboard to switch to the external display.


The key sequence can vary depending on the laptop, but is typically one of the following: Fn + F3, F4, F5, F7, F8, F9, or F10. For example, pressing the Fn and F7 keys at the same time could switch between your laptop and external display. The F key to be used may be labeled as CRT/LCD or have a picture of a monitor on the key or close to the key. Unfortunately, the keys pressed to switch displays is dependent on the model and manufacturer of the laptop. If none of the above key sequences work, consult your laptop documentation or consult your laptop manufacturer.

Note: For computers with macOS X 10.8 or later, if you have trouble getting an external display to work with the computer, access the System Preferences menu and select the Displays option. Then, press and hold the Option key. In the bottom right corner of the Displays window, you should see a Detect Displays button. Click that button to force the macOS to look for any external displays that are connected to the computer.

Some laptops can output video to both the laptop and the external display at the same time or to a single display. Laptops with this feature can toggle between the two modes when the appropriate function key is pressed.

Tip: Newer laptops and monitors may use a DVI or HDMI connection. See these links for additional details and pictures of these connectors. If your display has a DVI connection, but your laptop only has a VGA connection, you need to use a video converter that converts VGA to DVI.

Newer laptops may also have a DisplayPort, which can be used to connect external display devices that utilize a DisplayPort cable. If your external display uses VGA, DVI or HDMI instead, you can also get a DisplayPort adapter cable, allowing you to connect your VGA, DVI or HDMI display to the laptop's DisplayPort.
