If your screen resolution is 1366 x 768, it means that the screen has 1366 pixels horizontally and 768 vertically.
A few ways to find out the screen resolution:
- Refer to your notebook manual. It should be, as a rule, in the specifications section.
- If the manual is not available, take a look at the manufacturer's website and search for the laptop specifications in the support section by using the serial number and model of the laptop.
- If your computer is running, you can check your resolution online. Please note that this site shows the correct resolution only if you do not change the factory settings of the screen in Windows or Mac OS. On-line Resolution Check.
- And finally, the most reliable way to make sure what screen is for you is by the model number of the old screen, which is written on it's back. You can do a search on the model of the screen on ScreenCountry.com to find out the actual specs for size and resolution.
