TVs Vs. Monitors

[Dubfiance]

Hi, I'm new here and I'm not sure if this has ever been discussed, but I seem to notice a ton of similar instances with TVs and monitors and I am looking for an explination.

 

Every time you connect to a monitor the display fits perfectly on the screen without needing to tweak anything, however on a TV 9 times out of 10 the image is cropped all around the sides by a tiny bit until you fiddle around with the aspect ratio or other settings, sometimes even going as far as the graphics settings on your computer through dedicated graphics programs (intel, nvidia, amd menus) to manually correct the issue.

 

Why does this happen?

Because the settings on the TV are horribly wrong? 

 

That shouldn't happen.

A lot of TVs still ship with over-scan enabled.  This is a throw-back to a time when broadcast TV transmitted an image that was physically larger than the intended viewing image:

On a modern TV there will be a setting for turning it off; it might be called over-scan or native resolution or something, but the setting will be there somewhere.

Broadcast television and films (particularly older stuff) often had some junk around the edges, so in responses TVs have a setting which zooms the image in slightly to crop off the edges. On most TVs this setting is enabled by default. Older TVs sometimes do not even have an option to turn it off, but most modern TVs it can be turned off in the TV menu. It goes by different names, but usually it's a setting with the word "zoom" or "scan" in it.

Ehhh... Close.  It wasn't an issue for films since films when projected in a theater are will literally show the entire frame of the image.

The issue was CRT TVs.  Whey were kinda, well, wonky, so where and how far the edges would get cut off in a TV could vary by model.  Broadcasts had to account for 'title' and 'action' safe areas to be sure something would fit on EVERY TV screen.  CRT monitors could of course carefully adjust their edges but they also cost a lot more money relative to their size because they had more complicated hardware inside.

 

Though i'd argue that the REAL crime is the minority of HDTVs that have NO menu function to disable their overscan.  People should be shot for that. D:
