You put a film on in your browser, open a screen recording program, hit record, and what you get is a black rectangle. That is not a bug: it is exactly what was meant to happen. The same film that com...
You log out, delete every cookie, clear your history, open a private window and come back in. And the site still recognises you. There is nothing supernatural about it: most modern tracking does not r...
You buy a new TV, start a film with an HDR badge on it, and half the scenes look dimmer than they did on the old set. It is not a fault or a setting gone wrong: it is what happens when the file is ask...
