This also occurs to me, when I connect my TV to my laptop with the HDMI cable and start my computer, I'm forced in 1280xXXX resolution on my laptop's screen, and the TV gets the same low resolution while it can handle higher resolutions. The solution is, as Hadmut noted, to use xrandr, but I grew tired of this so I usually leave the low resolution.
Another irritating thing (I don't know if this happens to you too, Hadmut) is that when I have the TV on and connected to the laptop, the login screen's text input is acting strange: The size of the box is exactly the same, but the text that you type in (your user name and password) are SOOOO tiny, it's impossible to read (or even to know if you have entered all the letters of your user name) This is pretty strange, as for the rest the text behaves normally once logged in. I've marked this bug as affecting the "One Hundred Paper Cuts" projects, because for me this represents a paper cut, nothing devastating but quite irritant and surprising the first time you try this out. -- Wrong screen resolution with HDMI TV https://bugs.launchpad.net/bugs/350234 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
