The DVI output is connected to an LCD monitor. The AVR has the feature to pass through HDMI signal when put into standby mode. When I swit= ch AVR from/to standby mode it looks like it for a very short time interrupts = the connection from PC to TV and during this time it appears that the video card output turns off and monitor layout is re-aranged to one screen (DVI) only = and then almost immediately back two previous dual screen layout. Would it be possible to delay turning off the HDMI output for a bit longer so that it w= ould wait long enough that AVR would reconnect entire HDMI path to TV back again= and the HDMI output on video card would not need to be turned off and keep send= ing output in the meantime? So that the display layout configuration would keep being in dual-screen mode for the whole time? --=20 You may reply to this email to add a comment.
