    Need help adding higher resolutions for 1920x1080 display

    I am trying to run my monitor @ 1920x1080 on my ati 9600, but the display settings only go as high as 1280x1024 (and I am certain it is capable of the resolution, as it was used before i made the switch from vista rc1). I have edited /etc/X11/xorg.conf to add the resolution to the list, but this didn't work. I have added other resolutions (1920x1200 and 2560x1024), however only 1920x1200 was available, along with several other resolutions that i did not add to the list...any clue?

    If you know that the monitor is capable of the higher resolution, then you may want to try reconfiguring the xserver:

    From a Konsole session:

    sudo dpkg-reconfigure xserver-xorg

    This will take you through reconfiguring X. At one point you will be asked to identify all the resolutions that you want X to install.

      Re: Need help adding higher resolutions for 1920x1080 display

      Thanks for the suggestion. I ran through the setup and ran both the "simple" and "medium" setups for the monitor, however neither worked, and instead my system now boots into a resolution that I cannot display, with my monitor giving me a "signal out of range" message. I was skeptical about the "advanced" setup because I dont know what to input for the "horizontal sync range". Also, earlier in the setup when selecting available resolutions, 1920x1080 was not listed, so instead i checked several others in a range around that res, to see if it could be made available. I know that 1920x1080 (on a 42" lcd) is an uncommon resolution for computer systems, but it is because i intend to use it as an htpc.

        The 'advanced' option is no big deal. Accept the defaults for the frequencies - I did when I was trying to get Kubuntu to load X (and the KDE Desktop) on my 17" Toshiba laptop - and see if that makes any difference.

        What video card/driver do you have?

          Re: Need help adding higher resolutions for 1920x1080 display

          Thanks again for the help. I am running ATI 9600 (with what i believe is the most recent driver / fglrx). I did make some progress adding the necessary resolutions by taking some of the Modelines and settings from this post http://www.linuxquestions.org/questi...37#post2678037 , in the "monitor" and "screen" sections. I assume the values here should be accurate for me because he us using the same monitor/tv that I am (LVM-42w2). The result is that my resolutions are now all available, however, now that 1920x1080 is an option, it still does not display, with my monitor displaying "signal out of range". My assumption for this would be that the horizontal sync range is probably still incorrect. In System Setting>Monitor & Display>Hardware tab, when I view the configuration for the monitor it lists the horizontal range as 28.0-33.0, which is well below most LCD's (somewhere like 55-81). Not exactly sure where to go from here. I could try to reconfigure the xserver again, but I had assumed that the correct values should have been added by the lines I took from the other guy's xorg.conf. Let me know if you need to see my xorg.conf.

            Go ahead and post your xorg.conf file here. I'm going to do a bit of searching in the Forum, as I believe that there are some posts concerning fglxx video drivers.

                Fast post! Okay, I'll look your xorg.conf over. In the mean time, you may want to look at this post:

                http://kubuntuforums.net/forums/inde...opic=3082677.0

                This was a dual monitor issue, but it did involve the ATI 9600 video card, and the issue got solved.

                Posts due say that there are issues with the fglrx drivers.

                  Is the xorg.conf file you posted what the configuration setup created, or what it looks like after you tweaked it? Specifically, the following section doesn't look correct (to me):

                  Section "Monitor"

                    This is after I tweaked it. I took the lines from the link I listed where the guy had the same monitor. If you like, I can reconfigure xserver again and let you see the generated xorg.conf. However, whenever I run the xserver setup, it leaves me with a max res of 1280x1024.

                      Here is the generated file. Also, for the Hsync values i set them to 55-85.....I have no clue if that is right for me, but I do know that the 28-33 was too low for lcds, if you think i should go back, though, i can try.

                        Re: Need help adding higher resolutions for 1920x1080 display

                        From the xorg.conf you posted:

                        Section "Monitor"
                        Identifier "LVM-42w2"
                        Option "DPMS"
                        HorizSync 55-85
                        VertRefresh 43-60
                        EndSection

                        Section "Screen"
                        Identifier "Default Screen"
                        Device "ATI RADEON 9600"
                        Monitor "LVM-42w2"
                        DefaultDepth 24
                        Depth 1
                        Modes "1280x1024" "1024x768" "800x600" "640x480"
                        ....
                        If this is the xorg.conf generated from the installation, then based on the Modes, it appears that you didn't identify the highest resolution your monitor is capable of displaying. Was the resolution you want an option? Were the hor/vert rates suggested during the installation, or did you type them in?

                          These resolutions were the ones I chose, but only because choosing any other higher options has always xleft me with booting to a res that my monitor reports as "out of range". 1920x1080 is not listed as an available option, and choosing 1920x1200 was ineffective as well. I did alter the horizontal sync range because it did not auto-detect my monitor and the suggested range of 28-33 is usually to low for a lcd. the vertical refresh was the default.
