You'd expect one 1920 by 1080 screen to show something just as well as another 1920 by 1080 screen. And often that's the case, and it is with my recently bought tv set, but... Computer monitors are designed to show text, televisions are designed for moving pictures. Modern televisions do a lot of picture processing, trying to hide noise and errors, sometimes trying to enhance detail that's just not present in the signal, and will quite often mess up a live picture in the process (even worse when it's displaying a non-native resolution, such as standard defintion TV signals being upscaled by the set to high definition). The set may have some PC mode that puts the set into an optimal mode for use with a computer. On some sets, simply using PC as the name for the input does the trick. Otherwise, you may have to go through turning off all the special features (noise reduction, enhancers, motion effects, film modes, reality creation, overscan, etc). Overscanning is a particular issue with domestic sets (the picture is rendered beyond the edges of the frame, by slightly magnifying it). In television this has been essential for decades. Domestic TVs always overscanned, studios took advantage of that and allowed things to get into the camera frame that would never appear on the viewers set. Turn off overscanning, and you see the mike in shot, cameras filming off the edges of sets, etc, on a hell of a lot of tv programs. That's not usuall a problem with analogue signals shown on old-school cathode ray tubes, or even digital signals which don't use 1:1 pixel relationships. But with flat panel displays, overscanning destroys the 1:1 pixel relationship of input signals to display rendering, and things that require it (like small text), become smudgy. You get sets that lie, too. Saying that they're a certain resolution, but the screen isn't that resolution. I think the DPI issue is a bit of a red herring, in this instance. If you take three different 1920 by 1080 sets, each with a different screensize, they'll each have a different DPI. But they can each show the display as good as each other, though you'd use the bigger screens further away from you. So-called high definition (1920 by 1080) isn't particularly *high* definition, and doesn't stand too much close scrutiny. -- [tim@localhost ~]$ uname -rsvp Linux 4.14.16-200.fc26.x86_64 #1 SMP Wed Jan 31 19:34:52 UTC 2018 x86_64 Boilerplate: All mail to my mailbox is automatically deleted.
