Laptop LCD Screens come in different resolutions. Resolutions are the number of pixels per inch that a screen is able to display. Most screens sold today have TFT active matrix technology. The more pixels or higher the resolution a screen is the crisper the image. In addition, higher resolution screens allow more of a picture to be viewable.
Once a student came to me and asked “I want to upgrade size of my screen” It was little funny, I replied him “No, the screen size cannot be upgraded.”
and if you want to upgrade resolution it depends on the type of video card contained in your laptop and the availability of a compatible Laptop LCD of higher resolution, the screen resolution may be upgraded.

But sometimes it can also be due to a defective video cable or video card. To find out the actual cause you need to connect your laptop to an external monitor if the lines don’t disappear it definitely means you need to get a new laptop screen.
What if display is dim?
Usually dim display is because of a problem with the inverter or by the backlight (screen).

You can use different laptop screens with your laptop. Because normally the laptop manufacturer don’t produce there own screens and they use screens from different manufacturers in the same laptop model.
Do-It-Yourself Laptop LCD Repairs
Laptop LCD repairs usually entail a replacement of the LCD. One option is to look for a broken laptop to serve as a donor for the LCD. Or you can buy a new one from your laptop’s manufacturer.

You can ask the manufacturer of the LCD to give you a manual that has instructions on LCD replacements. With this helpful tool, you should be ready to do your own laptop LCD repairs.

The first step replacing an LCD is to remove the power cable and the battery. Next in line are the rubber grommets around the bezel. Make sure that you are using the right size of bit when working on the removals.
After you’re done removing the grommets, work on the bezel itself. Be extra cautious though. These bezels easily break as they are made of thin plastics. Also, bezels have a property that allows for an easy snap. This basically means a difficult job on unsnapping.
After a successful bezel removal, turn your attention to the metal frame at the laptop’s top lid. You will have to remove 14 screws before you can release the metal frame. After this step, you now work on the LCD. You have to lower the LCD panel into a resting position after which you remove 4 screws. This should release the LCD Replacement from the frame. Finally, unplug the wire connections ands remove the LCD panel.
It’s time to install your new LCD panel. Again, be very careful especially when handling your LCD panel. You didn’t buy a new one only to damage it. For a better protection, make it a point to lay down the panel on a soft surface. You can use a towel as buffer. Attaching the replacement LCD is actually doing the whole process of laptop LCD repairs I just mentioned above.
If I may reiterate, in laptop LCD repairs first thing to do is to reattach the four screws you removed from the old LCD panel after which you reattach the metal frame. You then lift the lid over the frame, just where you unattached it. You then reattach the 14 screws. Finally, you snap the delicate bezel back. This should be easier than the painstaking unsnapping process. Don’t forget to replace the rubber grommets and of course the bezel screws.
Now test try your laptop and celebrate all the benefits of doing laptop LCD repairs yourself. You get to save a lot of money and frustrations from dealing with sometimes impertinent technicians. And of course there is the prized benefit in the form of a sense of accomplishment.
Be careful not to turn the whole thing into a false economy. Be very careful in handling the delicate parts and be very meticulous with the instructions. You don’t want to turn a simple problem of LCD defect into a laptop overhaul. Remember that you intend to save money, not waste some.
