i just got my new 15 inch macbook pro yesterday, but i somehow feel my display is not as vivid as those shown in the retail store for the nature background resolution. plus, is it normal to load with a pure navy color background when i turn on the macbook pro after the pure white background with the icon of apple?
sorry, i just have nevered used mac os before, don't blame me for the ignorance of those 2 questions
If the colors you're seeing at startup really are
white (rather than light gray) and
navy (rather than a somewhat lighter shade of blue), something is wrong. But I doubt that's what you're really seeing.
There are a few possible reasons why your display might not appear as vivid. First things first, go to the Apple menu (top left corner of screen, apple icon) and choose System Preferences. In sysprefs, choose Displays and note the brightness level. Set it to maximum to see what your monitor is like.
Also note the "Automatically adjust brightness as ambient light changes" setting. If it's checked, this will be your answer when you start wondering why your screen keeps dimming and brightening unexpectedly. It's a whiz-bang neat-o feature that's cool for about two minutes. A lot of folks choose to turn that feature off.
You may also want to go to "Energy Saver" in System Preferences and choose to deselect the "Automatically reduce the display brightness before display sleep" feature, as this can be annoying for folks who are unaccustomed to it. Also notice the setting for "Slightly dim the display when using this power source" under the "Battery" tab. Some folks deselect this; I keep it selected because it increases battery life.
If the display still doesn't seem as vivid to you, go to
http://www.bergdesign.com and download SuperCal to calibrate your screen. This isn't quite as good as a hardware/software calibration tool, but it's a helluva lot better than Apple's built-in calibrator.
That's a lot of info, but hopefully you'll find it helpful.
