No Signal When Lenovo Laptop Is Connected To Various Projectors .

Hello,

the connection worked fine in the past, however since recently when I connect my lenovo laptop with Windows 7 using VGA to various projectors, it shows no signal on the big screen. The same lenovo model of my colleague works fine. My laptop recognizes that a projector is connected since the resolution of the screen is changing to the resolution of the projector and you can see the connection in the display settings! I tried to switch between various projector setting (duplicate, show only projector etc). I also updated my driver for the graphics car (Nvidia GeForce 410m)! Nothing works! Please help!

 

Projectors do sometimes behave a little differently - what happens if you just connect an external monitor to this notebook? Do you get a display on it? If not, then it would appear there is something at fault in the notebook. The fact the notebook seems to be sensing the projector's connection but fails to actually send the video signal could suggest a simple loose connector or loose or crimped wire, or the card is failing. Disassembling to look for loose connectors or wires is about all I can suggest. If nothing obvious, not sure there is anything more you can do but shop for a new notebook - assuming that one is no longer under any warranty. I don't suspect it would be cost-effective to send it in for repair. Sorry.

 

I haven't tried to connect the laptop to an another monitor! I will try that and let you know! Thx
