Ok, I'm not totally awake yet, so please correct me if my logic is off, but if i take the word clock from the n900 screen, it's 38 pixels wide. This means it fits 12.6315789 times on a 480px screen. When i then measure the width of the n950 screen on the screencap, and take the black borders in account, i get something like 1120px wide, and 76px for the word Clock, meaning that it would fit 14.73 times on that screen. Multiplying 38px with 14.7368421 gives me 560px, so I'm leaning more to qHD, and thus 960*540.
