Satellite L755-1HW - colours do not look natural on display

Question

I recently bought Toshiba Satellite L755 and I'm generally pleased with it. It's an upgrade from my Toshiba Satellite L300.
However I have an issue with the way it displays colours. At first glance everything seems ok, but then again some colours do not look right.
For example, gold on my old Toshiba looks 'gold'; on the new one it's kind of yellowish and generally, yellow seems to dominate in some ways and red is often not truly red.On the other hand, the old Toshiba seems to have a better picture; better contrast and more natural well saturated colours with no issues as above.
The colours on the new display look like they've been filtered and have some kind of tinge of an unidentified colour. I compared a number of photos on both laptops and the difference is consistent.
My L300 runs on default settings; the only thing I adjusted is brightness. I tried adjusting settings on my L755; brightness, contrast, hue, gamma, saturation but without any improvement.
I've done colour calibration and when I get to the 'shades of gray' they seem fine like everything else in this test and yet something's not right. I would appreciate any advice and I hope it's not just a poor quality display.
I cannot connect the laptop to another display, but I can paste screendumps if needed.

Answer 1

Connecting an external monitor would be a good test, but as I said at the beginning I don't have vga cables. I can compare colours on my old and new toshiba.
Perception of colours might obviously be subjective and without comparing, many would find nothing wrong with the colours on my new toshiba. However, I can tell warmer shades from colder ones and it's ultimately me using the computer.
I made a trip to a computer shop and looked at a number of different laptops and it's really difficult to see much difference in colours looking at e.g. Windows 7 sample pictures. In fact, when I look at them on my computer they seem OK and not different to what I saw on other laptops at the shop. It's only when I copied them to my old toshiba that I saw the difference.
Of course, you may say it's my old toshiba that shows colours wrong, but I'm sure you'd agree with me if you saw the difference. The colours are natural and warmer, something I cannot say about achieve on my new toshiba.
I used to have an excellent Samsung external LCD monitor and when I bought my old toshiba I was mostly disappointed with sharpness and angles compared to the samsung. Now this time it's the colours, notably yellow just like in the case of the person whose link I pasted. For them the problem disappeared after moving from intel (with HD Graphics 3000 as I checked) to AMD. That's why I asked about your card and impression.
Also, have you compared colours on your laptop with another one (older model) or connected it to an extenal monitor/tv?
