this may sound cliche but normally laptops have a special key combination which switches between internal monitor and external monitor (the sequence actually goes, Intermal Monitor Only, Both Internal and External, and External monitor Only).
what i do when the monitor is not regocnized properly, is that i disconnect the monitor, wait a couple of seconds, reconnect the monitor and press the key combination a few times to get the right settings. wait a few seconds between pressing the key conbination.
Other than that, perhaps there is some special configuration to look out for with this particular laptop so perhaps the manufacturer could help as well.
Thanks that worked just fine.
glad to hear that.
