I have just bought an HP nc6120 laptop and I am overall satisfied with it.

However, the quality of the display disappoints me, as it's noticeably worse
than my previous laptop: a Toshiba Satellite Pro, bought 3 years ago.

The images looks low-quality, like the range of colors would be limited.
This happens although the display settings are set to the maximum: 1024x728
32bit 16M colors

I would expect that notebook by a good brand (HP Compaq), would be at least
better than a 3 years old model.

At the end of this email, I reported the display and the video adapter specs
for both models.
Does anyone have comments on this?


Do these specs confirm a worst video quality of the HP model?

Or could it be a matter of not optimized settings?


Thanks a lot for any clarification!

Daniele

You didn't report the critical spec for one of them.

These are the parameters you want to compare:

> a.. typical contrast ratio : 150:1
> a.. LCD brightness (AC adaptor, super bright) : 70
