Ubuntu: HDMI/VGA connection cuts borders of screen or creates blurry text (8 solutions!)
Ubuntu: HDMI/VGA connection cuts borders of screen or creates blurry text The Question: Ok this is an extension of another problem I had with a VGA connection and an Nvidia Geforce GT 440 card. The question has been updated to include other problems related to HDMI Video and also since I have confirmed that it also affects ATI video cards. The explanation is the following: I have a Soneview 32' TV. This TV has many connections including VGA (First reason I bought it), HDMI (Second reason but did not have a HDMI cable at that time) and DVI. I have had this TV for little over a month now, actually I had it to celebrate the release of Ubuntu 11.10 and started using it exactly on that date (I know too much fan there but hey, I like geek stuff). I started using it with the VGA cable. After 2 weeks I bought an Nvidia GT440 card. The previous 9500GT which was using the VGA connection was working correctly with no problems whatsoever. I installed the GT440 and the first problem that I encountered using this latest card is mentioned here: https://askubuntu.com/questions/72245/nvidia-gt- 440-black-screen-problem-when-loading-lightdm-greeter. The solution to this problem was to actually disconnect then connect again the VGA cable. This would result in the screen showing me the lightdm screen for my login. If I did not disconnect then connect the cable I could be there forever thinking that there is no video signal. The black screen problem was solved in a later update for 12.04 and already solved using the default 12.10. So using 12.04 and updating or using 12.10 solved the black screen with HDMI problem. I got tired of looking for answers that did not work and for solutions that made me literally have to install Ubuntu again. I just went and bought an HDMI cable and changed the VGA one for that one. It worked and I did not have to disconnect/connect the cable but now I have this problem when using any resolution. My normal resolution is 1920x1080 (This TV is 1080HD) so in VGA I could use this resolution with no problem, but on HDMI am getting the borders cut out. Here is a pic: [enter image description here] As you can see from the image, the Launcher icons only show less than 50% of their width. Forget about the top and bottom parts, I can access them with the mouse but I can not visualize them in the screen. It is like it's outside of the TVs view. Basically there is like 20 to 30 pixels gone from all sides. I searched around and came to running xrand --verbose to see what it could detect from the TV. I got this: cyrex@cyrex:~$ xrandr --verbose xrandr: Failed to get size of gamma for output default Screen 0: minimum 320 x 175, current 1920 x 1080, maximum 1920 x 1080 default connected 1920x1080+0+0 (0x164) normal (normal) 0mm x 0mm Identifier: 0x163 Timestamp: 465485 Subpixel: unknown Clones: CRTC: 0 CRTCs: 0 Transform: 1.000000 0.000000 0.000000 0.000000 1.000000 0.000000 0.000000 0.000000 1.000000 filter: 1920x1080 (0x164) 103.7MHz *current ...
