This website www.isthisretina.com calculates what the standard of 20/20 vision could see. For a display with ~300 DPI, a distance of around 30 cm is the maximum distance where 20/20 vision will stop discerning the individual pixels. So, yeah, you're off by 2900%.
Of course, not everybody has 20/20 vision, which is why glasses, not denial, exist.
I don't know the track record of Lenovo when it comes to battery life claims, but 12h on the V, to be honest, seems to be optimistic based on what I see so far.
What's impressive is that the Lenovo is about 15% lighter at ~750g, while still managed to pack active cooling.
Also from the notebookcheck review up there, the Lenovo managed to make it last 15% longer than the similarly-specced SP4, so the i3 model should be really good. (The m3 SP4 lasts 60% longer than the i7)
Could it be because of MOQ? Lenovo has the deep wallet to pay the MOQ amount for their orders.
