T440p won't output to external monitor

#1 Post by Whitieiii » Sat Feb 17, 2018 1:05 am

I'm having a hard time getting my T440p to output to an external monitor it will not work over HDMI on docking station and it won't work via mini display port to HDMI adapter I don't have another HDMI cable to try yet and I've already updated my drivers but still get no output... my external monitor just says no signal... sometimes it will just flash from being on to off every 5-10 seconds.... the computer detects and sees the monitor just fine because my LCD panel in the computer goes into mirrored mode and doesn't fill the whole LCD panel... what else can I try in the mean time? I don't have another HDMI monitor to try and I don't have another HDMI cable long enough to try... any suggestions would be helpful as it's annoying

Fn-F7 comes to mind, as well as running Linux from a Live CD.
