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.
