Thanks for the answers. At the moment I said “no, is not possible” to the client that was asking me to color evaluate some pictures on a mobile PC.
I don’t need something perfect (and I also don’t 100% trust what I see on my monitor, I usually make an “hard proof” printing a sample when I am involved in color critical applications). I don’t think that anybody will ever be able to show on a monitor the difference between two papers with different texture-surfaces, I have some colors that my 7900 on certain papers reproduces that are outside my monitors gamut. My monitor resolution-per-area is smaller than my printer resolution, so it is also hard/impossible to have a good idea of the sharpening of the image... Sometimes you can trust your calibrated-monitor, sometimes you will need a print. I found limits in all the monitors that I have tested (and owned)…
I opened this discussion hoping that someone could understand that is not always possible to bring a good LCD screen with you... I need a fast, small, portable solution to show some files that need to be color-evaluated very fast. Sometimes you simply can’t say “I am sorry, you will need to come to my studio where we will see the pictures in my gray-painted room where I use 98% CRI lights and all the right hardware to do this evaluation”. I am of course not expecting good results, but maybe something “decent”. I know how hard is to get good color-matching, it is hard also to install properly a monitor in a studio if the light is not well balanced, so I am not expecting “miracles” from a laptop screen, but maybe something better than a 200k color TN display.
I know what limits a mobile display solution will have (related to ambient conditions).
I found the Lenovo X220, any idea about this product and his IPS screen? Do you know if the video card in this mobile PC has 1 or 3 LUTs? I tried to search but I had no success, maybe someone can help (or suggest a different product.
