      Hello,

       

      we've bought 3 zotac boards with atom D525 which has integrated gma 3150 graphics card.

      starting Xorg with screen on HDMI port yields something we don't understand:

       

      #> xrandr

      Screen 0: minimum 320 x 200, current 1280 x 720, maximum 32767 x 32767

      LVDS1 connected 1280x720+0+0 (normal left inverted right x axis y axis) 0mm x 0mm

         1280x720       60.0*+

         800x600        60.3     56.2

         640x480        59.9

      VGA1 disconnected (normal left inverted right x axis y axis)

       

      wtfl? 1280x720 is highest resolution on HDMI??? VGA does 1920x1080 fine. I don't understand... is this a hardware limitation or can this be fixed somehow in the driver or wherever?

       

      same on windows 7, btw.
