Confused about native resolution

From Wiki:

The native resolution of a LCD, LCoS or other flat panel display refers to its single fixed resolution. As an LCD display consists of a fixed raster, it cannot change resolution to match the signal being displayed as a CRT monitor can, meaning that optimal display quality can be reached only when the signal input matches the native resolution. An image where the number of pixels is the same as in the image source and where the pixels are perfectly aligned to the pixels in the source is said to be pixel perfect.[1]

While CRT monitors can usually display images at various resolutions, an LCD monitor has to rely on interpolation (scaling of the image), which causes a loss of image quality. An LCD has to scale up a smaller image to fit into the area of the native resolution. This is the same principle as taking a smaller image in an image editing program and enlarging it; the smaller image loses its sharpness when it is expanded. This is especially problematic as most resolutions are in a 4:3 aspect ratio (640×480, 800×600, 1024×768, 1280×960, 1600×1200) but there are odd resolutions that are not, notably 1280×1024. If a user were to map 1024×768 to a 1280×1024 screen there would be distortion as well as some image errors, as there is not a one-to-one mapping with regard to pixels. This results in noticeable quality loss and the image is much less sharp.

I understand that, just basically wondering why two different specs are published on that review...I guess that means the graphics card is capable of 1400x1050 through the external port?

There are two different panels that laptop can come with.

Page 7-3 lists a 1400x1050 model
Page 7-4 lists the 1024x768 model

Zyky is correct, that laptop came with the option of different monitors. http://h18000.www1.hp.com/products/quickspecs/12241_na/... The html manual is a bit easier to read. The VGA port supports resolutions up to 2048 x 1536 at 75 Hz.

Thanks. That's interesting. What is the easiest way for me to find out which version I have?

If you can set your resolution to 1400x1050, then you have that one.
