ThinkPad S540. Connection to projector is not working

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?

Hi Serge9,

 

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.


Best regards,

Hemanth Kumar

Dear Serage

 

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

 

Thanks

Alaa

Re: ThinkPad S540. Connection to projector is not working

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)

 

Nothing helped.

 

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
