Signs of a display defect can take on a wide variety of dimensions. This can be a cracked or broken screen, but also stripes, flickering or dark spots. This damage is usually caused by a fall or other mechanical impact. Single pixel errors are pixels that either show no or the wrong color. A completely black image does not necessarily indicate a display error. The defect can also have another cause.
The easiest and most efficient way to find the right display is via the manufacturer/model navigation. With the blue box in the upper left corner you can choose your laptop model. All compatible displays will then be shown.
For the display to be compatible with your laptop, the resolution must also be the right one. There may be different versions of the same laptop model. You can find the appropriate resolution for your new display in Windows under Settings under "Screen Resolution".
|HD (High Definition)||1366 x 768 Pixel|
|HD+ (High Definition Plus)||1600 x 900 Pixel|
|Full HD (Full High Definition)||1920 x 1080 Pixel|
|QHD+ (Quad High Definition Plus)||3200 x 1800 Pixel|
|WQHD (Wide Quad High Definition)||2560 x 1440 Pixel|
|UHD (Ultra High Definition)||3840 x 2160 Pixel|
With a matt display, the surface is roughened so that reflections in the display are greatly reduced. This can be particularly useful in bright rooms or outdoors.
Glossy displays have a smooth surface, which makes the image appear sharper. Colours and contrast are also better. Such a surface is often used in professional monitors for film and photo processing.
In most cases, we offer displays with both matt and glossy surfaces. So you can decide for yourself which of these two options you prefer.
In order to replace your defective display at home, you should have sufficient technical know-how. In addition, a removal guide specially designed for your laptop would be useful.
In general, however, we recommend that you have the display replaced by our experienced notebook technician. This is not much more expensive than a simple display purchase. In addition, you can be completely sure that your display will function perfectly afterwards. To get an idea of what such a display exchange can look like, we have filmed some repairs for you on our YouTube channel.
With a bit of technical knowledge and a manual specific to your notebook this could be possible.
We recommend letting a specialist do it.
Here a video as an example:
You have to measure the diagonal of your display by measuring from one corner to the opposite one.
You might have to convert from cm to inches. 1 inch is 2,54 cm, so a 19" display would also be a 48cm display.
When manufacturing a Display there can be errors in some pixels. This will result in the pixel or sub-pixel not letting any light pass or never blocking light. If a complete pixel is defective it will either be black or white. However, the same error can also occur in a subpixel, which will then result in it always/never displaying its respective color (either red, green or blue). Due to the very high number of pixels such errors are almost impossible to avoid, and that is why displays with a few pixel errors are still shipped.
Vertical or horizontal lines are almost always a sign for a display damage.
A display damage is also indicated by lines that (dis-)appear when the display is pressed on.
In this case the display has to be exchanged.
The digitizer is a part of the display; however, it does not display any images. Its main function is to protect the LCD underneath and it also handles touch input, if touch is present.
The LCD unit underneath the digitizer consists of the backlight and the LCD, which handles the colors of each pixel.
The display unit is all of this together. So, it contains the digitizer, LCD, backlight and usually a frame around all of it.
Only displays that are specifically made for your notebook are compatible.
Both are methods of connecting internal displays in devices like laptops or all-in-one PCs. LVDS stands for Low Volatage Differntail signaling and only specifies, that signals are transmitted using a lower voltage than usual. This allows higher data rates due to lower crosstalk and interference. When talking about the connection of a display via LVDS, the protocol FPD-Link (Flat Panel Display Link) is usually meant, which uses LVDS. This protocol has been introduced in 1996 and has been the main way of connecting internal displays for a long time. However, with the steady increase in the resolution of displays, FPD is reaching its limits.
That is why in 2008 Embedded DisplayPort (EDP) has been introduced. It is based on the external connection DisplayPort and is constantly being refreshed. It has no problem connecting displays with a 4K resolution at over 60Hz refresh rate, whereas LVDS is over at FHD (1080p).
TN, short form of Twisted Newmatic, panels have been the standard for flat-panel displays for a long time. Now they are being replaced by IPS (In-Plane-Switching) panels. The biggest disadvantage of TN panels is, that they only display a relatively small number of colours and that they have bad viewing angles. That means that if you don’t look at the panel in a 90° angel the colours quickly appear dull and distorted.
IPS displays solve these problems, they even show correct colours when looking at them almost at a 180° angle. However they still have some disadvantages compared to TN panels. They generally have a higher response time which means they take longer to display an image on screen. This is why gamers sometimes still prefer TN panels.
The difference is in the surface of the display. A matt display has a slightly ruff surface. This greatly reduces reflections, which is very beneficial for working in rooms with bright lights or outdoors. Additionally, fingerprints and dust are not so visible.
However glossy displays also have their advantages. Due to the extremely smooth surface the picture is a bit sharper and colors and contrast are also better, provided the display beneath the coating is good enough. Professional movie and photo editing monitors often use a glossy display in combination with a large anti-glare shield for the optimal image.
The part number can be found on the back of your Display, however finding it requires disassembly of your notebook.See also:
Nowadays, there are dozens of slightly different display resolutions for laptops and monitors. In order to stay on top of things, we created an overview of the most important ones.
Only when repairing ourselves we can guarantee, that the display will work 100% correctly with your device.
A lot of big companies use a custom firmware on their displays, this is why a replacement unit, even if physically compatible might not work as expected. However Displays are still listed in our shop, but not under the page of the notebook model, but rather by the part number specific to each notebook manufacturer.
If the Display is black, but the Desktop can still be seen a bit, this means, that the background light has died.
Some of the errors could be:
In most cases it is probably best if you send your device in for repair to a specialist.
