120 hz dynamically allocated, which means when you read text or do office work you save energy on a lower frame rate, and when you need higher frame rates for scrolling, movie or gaming it automatically increases it up to 120 hz. 120 hz on a 4 k display is something you can’t get from other brands. I have to uprade from my Lenovo X1 Carbon and have to buy a complete new Laptop just to get more RAM, but would have to downgrade the display as Lenovo doesn’t offer good display options in their Laptops anymore. I’m not going to sacrifice my eye sight to save Lenovo production costs. Fortunately, there is Framework now with their user orientated approach. And in the future, I won’t have to throw away a perfectly working high quality display and keyboard just to upgrade RAM, CPU, or ports, as all components can be swapped and independently upgraded on a Framework.
