JTL Yeah. First was XPS 13 9380 with the 1080p matte non-touch display. That was moderately painful to look at. Next I tried XPS 15 7590 also with the 1080p matte non-touch display. That was even more painful, possibly because I had to keep it at 26% to avoid PWM, while the XPS 13 did not use PWM.
Was pretty bummed about laptops, but my school was buying me one to use with assistive technology, and they buy Inspirons for students. We decided on Inspiron 7391 (non Black Edition), which comes with 1080p glossy touch display... and it's been good! Interestingly, it's painful driving any external monitor, but on the internal display I can use it. Has Chi Mei panel CMN1384. I inferred it is probably using 26KHz PWM based on this, from my notes:
Innolux bought Chi Mei and the panel has a different designation now, N133HCE-EPA. I got the spec sheet for it from panelook, but I don't know if it has any useful information or how to interpret most of it.
As an aside, I really like glossy now. I don't like the matte coatings at all anymore. Everything has much better clarity this way and the reflections don't bother me. I don't think this has anything to do with the pain though, as a glossy Macbook would cause instant pain.
