Re: G50 will not output video to hdmi connected monitor

Hi A1ci,

 

Welcome to Lenovo Community!

 

As per the query we understood that you are facing issue with system not able to connect to external monitor through HDMI on your IdeaPad G50.

 

  • Have you checked with different HDMI cable?
  • Are you connecting to External monitor or a Televisition?
  • Please check if the Graphic driver is updated? If not please download the file from the support site and install it.

Hope this helps.

 

Best regards,

Hemanth Kumar

Re: G50 will not output video to hdmi connected monitor

Here is what I did

  • Removed the graphics card and deleted the default drive (kit58411.inf)
  • The system reloaded the card and found the latest driver (igdlh64.inf)
  • The system boots and works on both screens UNTIL the laptop turns the screen off
  • Then the system cant see the hdmi connected monitor again
  • I plug and unplug the hdmi cable - still does not work
  • So I disable and enable the graphic card in device manager and then it works again (until the screen blanks)
  • I turned off the screen blanking when plug-in.
  • When I reboot the computer does not see the monitor until I disable/enable the graphics card

The bottom line is the monitor works fine (I have a acer laptop I can hook to it by hdmi and it works like it should) and the hdmi cable is fine (see above example).  There appears to be something wrong with the lenovo.

Hi A1ci,

 

This is not an issue with the laptop or with HDMI cable; in this case I think you are not installing the graphic driver properly. I suggest you to uninstall the entire graphic driver from the system through Control panel – Program and feature option, & download the latest driver from Lenovo support site, if the system is having dual graphic then install Intel graphic driver and after that go for other graphic driver (Nvidia, Ati).

 

Note: while performing this procedure please make sure you have not connected to internet or you can disable Windows driver update, because the windows will install generic drivers for your system.

 

Hope this helps.

 

Best regards,

Hemanth Kumar

Re: G50 will not output video to hdmi connected monitor

I have the same problem with my G50-70.  I had hoped that installing Windows 10 would solve the problem, but the HDMI is still not recognized in the Device Manager.  This feature is one of the reasons I bought this laptop, because it has both VGA and HDMI but the HDMI won't work.  What can I do in order for this to work properly?  Thank you.
