What are the different LCD screen sizes for laptop and tablet PC computers?
Laptop and tablet PC screens range in size from 8.9 inches to 17 inches. The size is measured diagonally based on the viewable area of the screen. Laptops may come in the following LCD screen sizes: 8.9 inches, 10.1 inches, 10.6 inches, 12.1 inches, 13.3 inches, 14.0 inches, 14.1 inches, 15.0 inches, 15.4 inches, 15.6inches, 16.0 inches, and 17.1 inches.
Can I upgrade the size or resolution of my laptop LCD screen?
Screen size cannot be upgraded. Your laptop resolution may be upgraded sometimes depending on the type of video card contained in your laptop and if there exists a compatible LCD screen of a higher resolution. We generally discourage against upgrading resolutions as it is not easy to determine a compatible LCD screen between resolutions.
Are some laptop LCD screens compatible with other LCD screens?
Yes. Laptop LCD screens may be compatible with other laptop LCD screens. Moreover, laptop makers like Dell, HP Compaq, IBM, Toshiba and Sony may source more than one LCD screen (as distinguished by the LCD screen's part number) even from different brand LCD screen manufacturers to install in the same laptop model. There are many variables to take into consideration like various physical constraints, electronic signaling characteristics and power issues.
Do I need a new laptop LCD screen if my LCD screen is dim?
You may or may not need a new LCD screen if the LCD screen is dim. If your LCD screen is dim it may be as a result of either 1) a faulty backlight or 2) a faulty inverter. The backlight is basically the light bulb in the laptop LCD screen which as one would suspect has an average useful life. The inverter, though, is a separate piece from the LCD screen. The inverter essentially 1) takes the DC power which the laptop runs off of and converts it into AC power and 2) steps-up the voltage to light up the cold cathode fluorescent backlight.
We have found that when a laptop LCD screen is dim the majority of the time it is a result of a faulty inverter (especially for HP laptop components). Unfortunately, the best way to determine which is the cause of the dim screen is through process of elimination by trying either a new LCD screen or a new inverter and seeing which solves the problem. We highly recommend you purchase an inverter first as inverters are less expensive than LCD screens. Screentopdoes not carry inverters, however, we would be more than happy to refer you somewhere.

The problem of DIM Screen
You can faintly see an image on your LCD screen, but it is too dark to use the notebook. Adjusting your brightness feature does not help.
The cold-cathode fluorescent tube(backlight) has gone out or the inverter is bad. Nearly 75% of the time, if your screen is dim, the inverter is no longer working correctly. The inverter powers the backlight in the notebook longer working correctly. The inverter powers the backlight in the notebook screen. We suggest that you replace your inverter first, before considering replacing your notebook screen.
The problem of CRACKED Screen
Your notebook screen is cracked. It may look like there's an ink splotch on your notebook screen. Although the surface layer of the notebook screen isn't damaged, the glass inside your notebook screen is.
Cracked notebook screens in general are not repairable and should be replace. Click here on "How to replace your LCD Screen".
The problem of LINES SCREEN:
A notebook screen defect whereby an LCD screen exhibits vertical or horizontal lines and is not due to a defect of the notebook itself (video card, etc).
Connect your notebook to an external monitor. If the image appears normal on the external monitor, it maybe most likely a problem with something other than the notebook screen, such as the video card.
The problem of BLACK SCREEN:
The screen is completely black. The notebook screen does not even show a faint image.
Make sure your brightness controls are not turned to the lower levels. If your brightness controls do not solve the issue, you may want to try hooking the notebook up to an external monitor to eliminate the possibility of video card failure. If the image shows up correctly on the external monitor, the backlight (CCFL) is faulty.
The problem of FLICKERING SCREEN:
Your notebook screen's image goes in and out.
You may want to open the notebook to make sure the video cable is securely fastened in the video data port on the back of the notebook screen. Also, be sure the inverter cable, located at the bottom of your screen, is also securely fastened.
Examine the video cable to ensure there is no damage to it, this may cause flickering too.
If everything seems to be secured tightly and there is no other visible damage, there's a good change the LCD is faulty.
