Paradroid2 Posted January 15, 2007 Share Posted January 15, 2007 (edited) Hi I have a laptop : the ZD8000 with radeon x600 and a 17" 1440x900 LCD panel Installed 10.4.8 I have a situation with the external display The 1440x900 is working on the internal ; but the external display (also 1440x900 LCD 20" on my desk) reports a 1152x864 input signal . The actual image appears to be the correct 1440x900 but is overshoots (parts of the image are outside the monitor's edges) Is there a way to get the correct external panel output ? I think it somehow misreads the DDC info the monitor sends to the PC , or the PC which sends wrong DDC info to the external screen . I don't want dual screen or expanded screen or whatever it is called . Just the same image as the internal screen has Does anyone know how I can tell the monitor on the external port that my signal is 1440x900 ? EDIT: I used a breakoutbox to disable all DDC communication between monitor and PC . Still the same . The width of the image appears to be within boundaries ; the heigt is not . I suspect a wrong frequency ... not much ... 59 Hz instead of 60 or so Edited January 15, 2007 by Paradroid2 Link to comment https://www.insanelymac.com/forum/topic/38823-zd8000-x600-secundary-monitor-situations/ Share on other sites More sharing options...
Turbo50t Posted February 13, 2007 Share Posted February 13, 2007 Your monitor should have a screen adjustment control panel, just readjust the horizontal and it should display just fine, mine did the same thing and that is what I did to get it back into the boundries.
