dmesg output in a .txt file

I observe that desktop image sent by computer trough hdmi connexion is bigger than tv screen. I can not reach the hidden piece of desktop with my mouse. The fonts has an uncomfortable size, really small. Not only that, but also Terminal mode(Ctrl-Alt-F1) shows an uncomfortable size, really small as well.

Close button on windows is shown also small, and the rest of buttons are missing. All kind of resolution screen has the same problem. Websites show untidy contents.

On the other hand, media player works correctly in full-screen mode.

Thanks a lots for your time.

Hi again!

I don't know if this can help in someway. I also observe that image sent by computer to tv screen is bigger because I see in Configuration Settings that the screen recognize is 72 inches, however, my tv screen is 44 inches.

I'm running Trisquel, but I have tried difference distributions(Ubuntu, gnewSense) and I have the same problem.

I have only tried all this things in gnome-fallback, gnome-shell (and Unity). In each case, the screen is overscanned. But only in gnome-fallback, piece of desktop is missed, I can't reach into that hidden space.

Lastly, I have been using a monitor, instead of LG tv, and there isn't any problem there, everything works pretty fine.

Let me know if you need more information.

Thanks a lot for your time.

This is known as overscan. TVs do it by default. Computer monitors don't.

(a) look for an overscan-related setting on your TV
(b) look for underscan-related xrandr properties (xrandr --props). You can futz with these to compensate for your TV's overscanning.
