Thomas Singh August 2, 2017 Share August 2, 2017 Hey! I just got my z820 back from service and one or my dual screens is black saying 'out of range'. Any idea what is going on? Tried to switch cables and screen and changed the screen resolution in Win 10 without any luck. Link to comment Share on other sites More sharing options...
Mazze August 2, 2017 Share August 2, 2017 Out of range usually means, the monitor is getting fed an unsupported refresh rate (e.g. 25 Hz instead of 60 Hz or so). Have a look at that and see if it gets you anywhere. 1 Link to comment Share on other sites More sharing options...
Abby Bader August 2, 2017 Share August 2, 2017 (edited) It could also mean that the dektop resolution is set higher than your maximum screen resolution. Edited August 2, 2017 by Abby Bader 1 Link to comment Share on other sites More sharing options...
