I've got a my 5870 mobility working, following a tutorial (http://www.insanelym...howtopic=249669) It involves using a boot and rom file from another person. Internal screen works on high resolution. HDMI or DVI work (DVI using a trick involving rebooting with cable connected) But these outputs don't work simultaneous. It is not possible to have all three (internal, HDMI, DVI working simultaneous? Or maybe because the person has a slightly different type of 5870 (VGA instead of DVI)?
Are there ways to test or edit settings to get the DVI and HDMI output to working simultaneous?
