    Ubuntu will only allow 1024x768 or 800x600 resolution options for my external monitor, an HP 2159m (which supports 1920x1080). The laptop's built-in monitor works fine.

    I'm running Ubuntu 12.04 and my graphics card is an Intel HD 4000.

    Do I need to update the drivers? Can someone point me in the right direction?

    Many thanks

  • Hi adamf,

    To use the Graphics Installer, you will have to upgrade to the latest version of Ubuntu which is 13.04.

    In general, however, you will have to dive into Ubuntu's display settings. Some desktop environments attempt to find a "common" resolution across displays. Consult Ubuntu's documentation for how to "extend" your desktop across multiple displays so you can utilize your external monitor's highest resolution.

    Cheers, hope that helps

    Can confirm a very similar situation with my Lenovo G400 running Ubuntu 13.04 and a 32" LG LCD TV which is capable of diplaying 1366x768 but only has 1024x768 and 800x600 as options for the extended display.  Is this a common problem?

  • Hi ericdraven,

    Alas, "TVs" introduce some complexity. Overscan and other issues bite users all the time.

    I have a circa 2006 digital TV at home that, per its documentation, is capable of a max resolution of 1080i. However, whenever I plug it in via HDMI to may favorite computers, it exposes a preferred resolution of 720p-- less than the documented maximum. All the while my game console gets 1080i. I yield to your favorite search tool to explain why this is-- I'll have to delve into it sometime.

    Some digital TVs have a "PC Mode" or like setting that plays nicer. I'm looking at my second monitor (technically a "TV") that has such a setting and made my life much easier. Is that option available on yours?

    Thanks for replying to the question!

    The thing is, I'm not even after whether my 2009 LG LCD TV is capable of 1080p or i.  It just says in the TV's documentation that the set is capable of displaying 1366x768, and I'm not even getting that option when I connect the TV to the laptop.  I have it hooked up through a VGA connection, and my graphics card supports the resolution (945GM), so I'm wondering why the 1366x768 setting isn't even offered at all.  And you're right, the TV has a "PC" setting that I switch to when I try to connect it to the laptop.

    I guess, for now, it's off to the favorite search tool for additional info :) please do comment again when you have more info on this.  Thanks!
