My daughter is wondering why the same image on her laptop has the blue tinge. The end result is true when printed. The laptop is about 3 to 4 years old now. She is considering upgrading as she is going to Uni next year doing graphic design. So another question would be, she can't afford to buy an apple (that is her dad can't) what should she be looking at spec wise for a new laptop. Thanks

It has a cooler colour temperature. Natural white point is something like 6500k


See this review on anandtech for a comparison


In comparison the imac looks much warmer, its not necessarily more accurate, but probably is.

If neither screen has ever been calibrated then a difference is normal.

One indicator of how well a display might be able to be calibrated and how consistent it will be when viewed off-angle is to look for something with an IPS panel display (normal low cost laptops tend to have TN display panels).  I don't  know how successful you'll be finding an inexpensive laptop with the grunt to run photoshop etc comfortably, also with IPS panel and hopefully reasonable battery life.  Macbook Pro and Surface Pro seem expensive, but by the time you've got those specs in another brand, the price premium has evaporated.

I'm guessing it's an cheap laptop, the screen in your iMac probably costs more then her whole laptop. Apple put a lot of focus on having good looking, accurate screens in their computers, hence why they are so expensive (you are probably looking at well over $1k if you had to replace your iMacs screen). Apple screens are also pre-calibrated, I'm not sure to what standard, but a fairly high one (even their phones).




You may get an improvement on her laptop if you calibrate it, but it is likely a cheap laptop/screen, and is never going to look as good/accurate as the iMac. Your best bet is to either do some research on the inter-webs for a good accurate screened laptop (they do exist), or go into a large retail store, with an digital image, and an printed version of it, and put it on their laptop screen and see if you like how it looks. Also just a note, the consumer lines of laptops you see in retail stores, will in general haver lower quailty screens then the same brands Business models. For example Toshiba Portege's and Tecras, vs their Satellite range, but you are also talking more $.

All display's no matter what level require some form of correction to output to sRGB standard.
This includes professional monitors, medium grade affordable monitors and general run of the mill displays.

The more you pay "generally" you might get the ability to tweak the monitor itself to get reasonable adherence to standards. Laptops are a minefield, rarely they will even calibrate to standards.
Applications and windows do their best to ignore PC based calibration software, some software does pickup corrections in the windows profiling. Apple has it's fun practices as well however do need work.

Fundamentally if the display default output is too far the standards there isn't enough adjustment to correct the output. Main reason in laptops is lack of luminance, simply not bright enough. They push blue to try and convince a casual viewer that the image is brighter. Correct the image so that the RGB balance is the correct white point and the display can lack life, become dull.

The windows calibration guide can help with the basics, however to really do it correctly you need a measurement device and software to modify the profile and even manage it with some software.
