My HDTV has a pc setting mode that good?

For most of TV's history, we used CRTs (Cathode Ray Tubes) to display the image. CRTs often had distortion at the edges, and so it was normal and common for TVs to "overscan" the image - meaning the image was stretched beyond the viewing area of the TV, so that some of the outside edges of the picture were cut off.

On over-the-air broadcasts that contained Closed Captions, the code for the Closed Captions was sent on scan lines that were normally cut off by overscan, in fact, and this artifact can still be seen today.

"PC Mode" on your TV likely just means that overscanning is turned off. And for the vast majority of your sources - digital sources - that's fine, because most content broadcast today is sent out at a fixed resolution that will fill your entire screen perfectly when overscan is turned off - BUT, if you, say, have an old analog source, like a VHS or an old game console with Closed Captions, if overscan is off, you can see white dots or lines at the top of the image, and the image may not go all the way to the edges of the screen the way modern content does. Having overscan on can make this look more presentable because it will cut off those edges. In "PC Mode" (or "Dot for Dot" or "Full Image" or whatever the TV company calls it), you'll see those artifacts on lots of analog-sourced content.

I think its just a mode so you can connect your pc to your tv and use your tv as a monitor.

[Supergodman12]

Yeah isn't that nice though?

[Astarlessnightsky]

I don't know, its a thing. Question is how often are you using this.

[Supergodman12]

I used to use it a lot but now not at all
