My experience with ThinkBook and Intel Iris Xe graphics

This is about ThinkBook 14 G2 ITL model but it applies to all ThinkBook and Intel laptops. Old review but still will share my experience for those considering it and related models. I bought this computer for all the reasons listead above: excellent upgradability, HDD bay in 14 inch format, great sound, USB charging while the device is off (Asus stopped this one years ago), so based on paper, it should be the perfect laptop by any means. But the screen, this screen...i think nothing hurt my eyes so much in my life, PWM or no PWM. First i noticed it has 'something' giving me a slight vertigo when looking into it. I thought it's the colours, the contrast, the matte surface... I was spending for a week 40% of my working time just trying to configure the screen. Nothing worked. Until i found it: temporal dithering. A viscious form of flickering that is undetected or nearly impossible to detect, except through your own side-effects. So that was it for me. I downloaded a program that was supposed to alleviate the problem and it did. I could watch the screen not for 15 minutes but for an hour maybe, but unnecessary to tell, any pleasure was lost in owning this laptop. After having gone to sleep three straight days in a row with a migraine that would last through the night, i decided it was time to sell it. This issue is not Lenovo or ThinkBook related, it's the hardware implementation of the Iris Xe graphics, so there is nothing you can do about it, except get a PC older than Intel 11th gen (or i3 11th gen), or AMD and others. That's it, hope for someone this advice has been usefull, i've found temporal dithering way more harmful than PWM and even less justified or even completely senseless. I'd rather have a bit worse but healthy image than this thing.
