Win 7 Pro (64bit)
When HDMI cable has been connected and laptop has been switched to duplicate screen mode the projector (Acer) shows that HDMI port is connected but nothing is visible in the screen except info messages (HDMI connection, etc.).
What can be a reason that brand new S540 does not work with projector through HDMI link?

Welcome to Lenovo Community!
As per the query we understood that you are facing issue with connecting Dual display through HDMI on your ThinkPad S540.
Have you checked updating latest graphic driver from Lenovo support site?
Hope this helps.

Welcome in lenovo community
First of all there is some point we need to make sure of :-
1-Have you tried another cable
2- Have you tried the VGA cable
3- Have you checked the Graphic card in device manager if installed or not .
Let us know

Sorry for delay...
1. Drivers were latest one according to version num numbers. Date somehow were different and I updated them
2. No problems were shown by Device manager
3. Several cables were checked (actually 3 different cables)
4. There is no VGA connector in this laptop (ThinkPad S540)
But after that I went to settings of display (Intel blah-blah-...) and decreased the quality of signalfrom maximum to 12xxx760. It helped.
Seems projector is not suitable for such quality of signal
