Thanks for the insights.
Yeah well.. the Lenovo P51s (upcoming) looks lovely (compact yet powerful), but it seems like (a) it does not come with quad core processors, and (b) the screens are -again - PWM and 60% Adobe sRGB coverage AT BEST. Sigh..
why do you care about rgb ? none of the laptops have very good screens, they're OKKKK, even if it has high coverage, it's not going to have very good uniformity because of the way these screens are mounted, it's not on a rigid surface leading to non-uniformity as is, or develop non-uniformity over time..
High spec sRGB/Adobe RGB is a major factor as to why people buy Macbook Pros. C'mon tp4tissue.
maybe for n00bs or wannabee photographers. hahahaha.
Gray/white uniformity (backlight) AND color uniformity are an issue across the whole spectrum of monitors nowadays, not only monitors found in laptops. In my experience, the only way to truly salvage that is donating some organs to buy a professional high-end monitor with serious uniformity compensation, like the PA272. Even Dell's high-end monitors suck, comparatively speaking. Eizo also has some color accurate displays.
Typically, uniformity is an issue on larger panels (24" and above), not so much on lower panels, as reviews of the Razer Blade and XPS screens (Sharp or LG panels? I forgot) indicate. I'm not sure what Apple puts in their MacBook Pro's nowadays, but those also have fairly good uniformity scores, both backlight uniformity as well as color uniformity. As a matter of fact, Apple's screens even support the P3 gamut stantard, which exceeds sRGB coverage.
I am, actually, a semi-pro (outgrown hobby) photographer, but I do not have money to buy expensive monitors, probably because I buy too many boards and stuff
. So I try to get the best bang out of the buck. And Lenovo's screens REALLY ARE CRAP, except for the one's they put in the X1 Carbon and the YOGA.
Lenovo laptop screens typically have only up to 50% Adobe RGB coverage, whereas more high end laptops (XPS, Razer Blade, MacBook Pro) have 98-99% coverage, they have PWM, low nits (<= 250 nits), bad uniformity, backlight bleeding like your 32" IPS panels, and ghosting. The only upside is that they have matte displays.
I'm really REALLY sensitive to PWM, so I replaced all my monitors with non-PWM screens and never since then have I had eye issues. Alongside color accuracy and overall quality of the screen, I cannot choose a Lenovo that features a crappy screen, even though I really like the T470 / P50 / P51 otherwise.
The alternative would be the Dell XPS but yeah... so many issues. Throttling, heat, noise, warped case, backlight bleeding, dead pixel, battery life issues, coil whine. W T F.
