Hi all

 

I have a Dell Vostro 3500 with Nvidia 310m graphics card and HDMI output port.  

 

Firstly, my video card seems to have massive issues with the Nvidia driver - I can install an intel hd graphics driver for Windows 7 and it runs fine, but if i install using the Nvidia driver from their webisite or from the dell website, it just crashes on start up.  I beleive it operates on a dual graphics processor system whereby I can run with the onboard intel driver fine, but for anything more intensive the Nvidia kicks in and so presumably im crashing because of a fault with that when it self checks or something on start up.  Anyway...all that is by the by, im happy running of the intel driver asi dont do gaming and it runs perfectly ok.  Just to note in advance that the graphics have some issues...

 

However my actual quesiton is regarding connecting my laptop to my TV via HDMI.  Just got a new tv with HDMI input and would like to connect my laptop to it via HDMI.  I tried this last year on another tv and I couldnt get it to show on the TV screen, and my housemate can connect his laptop to my TV fine so we can assume the TV side is working fine and its a laptop issue.

 

When I plug the HDMI cable in I get the "usb connection" noise from windows (Windows 7), the screen on my laptop briefly goes blank then comes back.  I am connected. However I get nothing on the TV screen when I go to the correct HDMI input.  I have gone through the settings on the graphics properties - it lists two monitors, my laptop monitor and the TV by name, so it knows its there.  I have tried "extend screen", and "duplicate screen" and all the others, and still I see nothing on my tv.  Identify screen gives me a "1" on my laptop but obviously nothing on the TV. 

 

So the TV works and cable works, the laptop seems to recognise the tv, acknowldge the HDMI cable and is supposedly sending a signal, but im getting nothing on tv.

 

So....any suggestions?

 

Cheers!

Did you purchase your laptop Before Oct 2010 or after?

According to dell 

 

All 3500's shipped before Oct of 2010 will have either integrated Intel, or discrete Nvidia.  Systems sold after that will have switchable graphics.

 

You need  the Nvidia 310M discrete driver from dell. When installing make sure you follow the correct install order and reboot every time your supposed to. If there is still a problem using the hdmi try this. Turn off the laptop, turn off the tv, plug in the laptop charger, connect the tv to the laptop and turn on the tv. Make sure the tv is set to the correct hdmi input. Turn on the laptop and see if you can select the external screen. Lastly check your memory using Memtest 86 a loose or failing module won't have enough system memory available for the graphics chip to load properly.

Edit: There are other options listed by the dell support representative in the link above. Checking the nvidia website, there was no option to select the discrete 310m driver,

Thanks for your help, its appreciated...

 

Hadnt considered it an issue, but due to what is basically poor design by dell, these laptops suffer from over heating after dust clogs up the fans after a year or two of use.  I recently disamantled and cleaned mine to resolve just this issue - however, I called dell to report the problem while my laptop was under warranty and they sent a technician out who replaced the motherboard, this would have been around may 2011 - i am presuming they replaced with a later motherboard which has switchable graphics as mine does seem to show both intel and nvidia and allow me to disable one and run off the other.

 

However for the record I have installed and re-installed the Nvidia driver both from the Nvidia website and the Dell website and still seem to struggle with it....will give the steps you suggest a go and let you know what happens

 

Thanks!
