  • I don’t think it’s correct though.

    The graph suggests that you should be looking at a 65-inch screen from a distance of 120 cm for resolutions above 4k to be worth it. I interpret that as the distance at which the screen-door effect becomes visible, so this seems awfully close actually.

    A 65-inch screen has a width of 144 cm, which gives you a 100 degree angle of vision from the left edge to the right edge of the screen. Divide the approximate horizontal resolution of 4000 pixels by 100 and you get an angular pixel density of 40 PPD (Pixels Per Degree).

    However for the pixel gaps to become too small to be seen or in other words for the screen-door effect to disappear, you need an angular pixel density of 60 PPD. That means you can sit at a more reasonable distance of 220 cm in front of a 65-inch screen for resolutions above 4k to be worth it.

    This is still too close for comfort though, given that the resulting horizontal angle of vision is 66 degrees. The THX cinema standard recommends a horizontal viewing angle of 40 degrees.

    So multiply 40 degrees by 60 pixels per degree to get a horizontal resolution of 2400 pixels. That means the perfect resolution for TVs is actually QHD.










  • Oh, Apple’s ecosystem is absolutely brilliant, but the problem is that it only works with Apple hardware and software with no indication of future cross platform compatibility. So you basically get suckered into buying Apple products only, if you want to keep your passwords, documents, podcasts, etc.

    Like migrating into Apple’s platform is easy, but moving back out is almost impossible. The main problem lies with how irritating it can get to consume content provided by services outside their domain.

    Personally I am happy with my Macbook, because I can still download and install apps without using the App Store, but I could never see myself migrating to iOS because that would mean losing my manga collection, my emulators, the ability to watch free movies on Stremio, etc.

    Edit: Oh, yeah the iOS keyboard is an absolute travesty. It makes textboxes so frustrating to deal with. How can you have a virtual keyboard without a clipboard in this day and age?
