How to find the correct replacement screen for your laptop

Replacing a damaged or faulty laptop screen can often be a much more cost effective option than replacing the entire laptop. Whether you’re dealing with a cracked display, flickering screen, dead pixels or a completely black display, finding the right replacement laptop screen is essential.

However choosing a replacement screen isn’t always as simple as matching the laptop brand and screen size. Two laptops from the same manufacturer can use completely different display panels, connectors and specifications.

In this guide we’ll explain how to find the right laptop screen for your model, what information you need before ordering, and some of the key specifications to check when buying a replacement laptop screen.

Find Your Exact Laptop Model Number

The first and most important step is identifying the exact model of your laptop.

Knowing that you have a Dell, HP, Lenovo, Acer or ASUS laptop isn’t enough. Manufacturers produce many different models, and even laptops within the same product range can have very different screen specifications.

There are several places you may be able to find the model number. It may be displayed on the bottom of the laptop or on the original box. If not you can boot the laptop up and check in the BIOS or in Windows system information.

Look for a specific model number rather than just the manufacturer name.

For example, “Lenovo ThinkPad” describes a product family, whereas a more specific model number identifies the particular laptop you have.

The serial number can often be used to identify the model number of the laptop and the exact screen required. If contacting us to buy a new screen please provide this if possible.

Check the machine’s documentation

Checking the maintenance manual for the machine, either in paper form if you have it or online, can often provide information on the correct part number for the screen. Occasionally the manual will cover multiple models however and the screens listed may have slightly different specifications or not be compatible with your machine so in these cases more research may be necessary.

Contacting the laptop’s manufacturer is often worthwhile as they may be able to provide a replacement part number based on your laptop’s model number or serial number.

Check the Existing Laptop Screen

Many laptop screens have a label on the rear containing a screen part number or panel number. This can be more useful than the laptop model alone because it identifies the exact display panel fitted to your machine.

You may need to carefully remove the laptop’s LCD bezel and detach the screen from the rear cover to access the label. If you’re not comfortable doing this, it’s often better to have a qualified technician check it for you.

A part number might look like a combination of letters and numbers, and it can usually be searched to identify the screen’s specifications. There can be multiple part numbers, one may be a part number listed by the laptop manufacturer- Dell, HP, Lenovo etc and one may be the part number used by the screen manufacturer themselves.

If you have the panel part number, include it when searching for a replacement laptop screen.

Screen Size 

Screen size is one of the most obvious specifications to consider, but it shouldn’t be the only one.

Common laptop screen sizes include:

• 11.6-inch
• 13.3-inch
• 14-inch
• 15.6-inch
• 16-inch
• 17.3-inch

A 15.6-inch laptop screen, for example, may be available with several different resolutions, connector types, refresh rates and panel technologies.

This means that simply searching for a “15.6-inch laptop screen” isn’t enough to guarantee compatibility.

The physical dimensions of the panel, mounting points and connector position can also vary.

Screen Resolution

Screen resolution is another important specification when choosing a replacement laptop display.

Common resolutions include:

• 1366 × 768 HD
• 1920 × 1080 Full HD
• 1920 × 1200
• 2560 × 1440 QHD
• 2560 × 1600
• 3840 × 2160 4K

If your original laptop screen is Full HD, you may want to replace it with another Full HD panel rather than assuming any screen of the same physical size will work.

In some laptops, upgrading to a higher-resolution display may be possible, but compatibility needs to be checked carefully. The laptop’s motherboard, display cable and BIOS may all affect whether a different panel will work correctly.

For a straightforward laptop screen replacement, matching the original specifications is generally the safest approach.

Screen Connector

One of the most important compatibility factors is the screen connector.

Modern laptops commonly use eDP (Embedded DisplayPort) connections while older machines may use LVDS connections.

Even when two screens use the same general type of connector, they may not necessarily be interchangeable. Connector pin counts, cable arrangements and other specifications can differ.

For example, an eDP panel might use a 30-pin or 40-pin connector.

The position of the connector can also matter because the laptop’s internal display cable needs to reach it correctly.

It is important not to assume that 2 panels are compatible because they are the same size and resolution. If you aren’t sure which connector your laptop uses, checking the original panel’s part number is often the easiest way to identify the correct replacement.

Consider the Panel Type

Laptop displays are available with different panel technologies, with IPS and TN being two common examples.

IPS panels are generally known for offering better viewing angles and good colour reproduction, making them popular in modern laptops.

TN panels can be found in some older or budget laptops and can have different viewing-angle and colour characteristics.

There are also different types of finishes, such as matte and glossy.

If you’re replacing a damaged laptop screen, matching the original panel type and finish can help ensure the replacement looks and feels similar to the original display.

Don’t Forget Touchscreen Compatibility

If your laptop has a touchscreen, make sure you specifically check whether the replacement display needs to support touch functionality.

If your laptop originally came with a touchscreen, make sure the replacement part is explicitly listed as compatible with the touchscreen version of your model.

Mounting Points and Brackets

The panel’s physical design is another consideration.

Some laptop screens are secured using side mounting brackets, while others may have different mounting arrangements or rely on other parts of the laptop chassis.

The replacement screen needs to physically fit inside the laptop lid.

This is another reason why matching the exact panel number can be preferable to simply buying a screen based on size.

A screen can have the correct dimensions but still be unsuitable because the mounting points or physical layout are different.

Can You Upgrade Your Laptop Screen?

Depending on the laptop, it may be possible to replace an existing display with a higher-resolution or better-quality panel.

However, screen upgrades aren’t universally compatible.

Before upgrading, you’ll need to consider the display cable, connector, resolution support, power requirements, mounting points and whether the laptop’s firmware supports the new panel. It is best to consult the machine’s manual or contact the laptop manufacturer directly to confirm what options are available.

For this reason, an upgrade should be treated differently from a straightforward replacement laptop screen.

If your priority is simply getting a damaged laptop working again, replacing the original panel with a compatible equivalent is usually the least complicated option.
