Lenovo Ideapad S540-14IWL - all the listings in lazada, shopee only got model with fhd 250 nits, 45% srgb which is crappy screen

in lenovo website, said that up to 300 nits, 100% srgb screen but no button to buy

any suggestions? thin and light, at least nvidia mx250 (prefer full-power mx250), 8gb ram, metal body no plastic

acer swift 3 is near perfect for my usage but too bad nvidia mx250 is crippled version
