Well response time wise they're worse than the new Macbooks, and those are pretty terrible: https://twitter.com/andreif7/status/1452622025550438403 https://twit

They're not actually using the Innolux display this year sadly, only the AUO and BOE panels (which both have awful ghosting). Once you know what to look for (or feel, since bad ghosting gives me headaches and eyestrain :/), it becomes obvious.
- shmerl 5y agoIs the higher res panel better for them?
- elabajaba 5y agoI'm not sure which exact 4k panel(s) Lenovo is shipping with the T14 this year. From what notebookcheck has tested, the P14 4k panel they had was pretty good (still a bit slow, but usable, and no PWM), while the X1 carbon 4k panel they got was unusable (fast enough, but 200hz PWM so basically guarantees that it'll cause headaches).
- shmerl 5y agoWhat exactly does PWM affect and how do you check if it's used?
- elabajaba 5y agoComment chain was too deep so I couldn't reply. Good article on PWM: https://www.notebookcheck.net/Why-Pulse-Width-Modulation-PWM-is-such-a-headache.270240.0.html https://www.notebookcheck.net/Why-Pulse-Width-Modulation-PWM... I think you need an oscilloscope and some other tools if you want to test what the PWM frequency is. The easiest way to check for PWM is to just look up reviews for laptops using the same panel (you can find the panel number using hwinfo on Windows). To just test for if your display has PWM, lower the brightness, and use the blurbusters test: https://www.testufo.com/blurtrail https://www.testufo.com/blurtrail
- shmerl 5y agoThanks for the pointer. Sounds like PWM frequency is something that should be specified in the screen specs.
