Latitude E6420 HDMI Output

Okay, maybe this sounds silly.  But I have an E6420 with this fancy HDMI port on the back of it.  And I have a 6 month old Toshiba TV with plenty of empty HDMI-in ports.  How the heck do I get it to display on my TV?  Apparently just plugging in an HDMI cable isn't the trick, because nothing happens.  Is there some kind of Fn+F8 combo like there is with VGA that I need to use or something?  Thanks!

Re: Latitude E6420 HDMI Output

Hi igendreau,

Welcome to the Community.

Once you connect the HDMI cable between the TV and system,you need to select the Input source using the remote or the menu on the TV itself ( Example HDMI 1 or HDMI 2 depending on which HDMI port you have used on the TV)

Than on the system go to Control Panel,Display,Change Display settings.

On that window you’ll see that it shows there are two different displays, but one of them will be disabled.

Click on the second monitor then choose “Extend the desktop onto this monitor” and click “Apply”. The HDTV screen should come to life and show you a Windows desktop background photograph. If it doesn’t, try again. Sometimes you have to select this more than once.

I recommend that you now tweak the resolution on the second screen to be at least 1100 x 650, depending on what options you have.By adjusting the resolution you can have the background photo spread across the TV screen.Make sure the sound is not muted and adjust the volume on the TV and system accordingly.

Now you can drag things across to the TV screen and use TV as the extended display.

Hope this helps,

Thank You

Roshan.

Re: Latitude E6420 HDMI Output

I'm very familiar with using VGA with external monitors, TVs, projectors... both to clone or to use as extended desktops.  So what you're saying is, it should basically work similar to that.  I was just wondering if the HDMI process is somehow different.  For some reason, my laptop isn't showing up on the secondary screen.  Maybe I'll try updating the NVidia driver and see if that helps matters.  Thanks for the update though!

I have a brand new E6420, and although 2 monitors (a DVI and a VGA) are hooked up, it will only recognize one of the monitors.     Plese help

Re: Latitude E6420 HDMI Output

Here's what I ran into, and how I fixed it:

We use 6420s, and I noticed in device manager that they have BOTH Intel AND NVidia video drivers installed.  The only conclusion I could find was that Intel was driving the computer's LCD display and NVidia was driving HDMI.  So, if I would use the keyboard (Fn + F8) to change the display, it would work fine for VGA connections, because those fell under the control of the Intel card.  Same thing for if I chose "screen resolution" from the desktop.  All those were only addressing the intel card, which controls VGA and built-in display.

To use HDMI, which falls under Nvidia, connect your cable and then right-click on the desktop and choose the Nvidia control panel.  From there, you can control display cloning and extending the display to your HDMI monitor/display.

Hope this helps someone- I spent a lot of time tearing hair out over this.

Hi Muthu,

Welcome to the Community,

Try the steps below and see if it helps :

Turn off both TV and your Latitude system.

Connect the HDMI cable between the TV and system.

Turn on both TV and system.

Select HMDI input on the TV Display menu.

On the system go to Control Panel,Display,Adjust Resolution,click on Detect.

It should ideally detect the Sony TV connected to your system.Then you can select Duplicate display to get the system display on the TV.

If this does not help post for your full system model with Windows version installed.

Example Latitude E6420 running with Windows 7 (64 bit).

Re: Latitude E6420 HDMI Output

Hi Guys,

In my case the problem was the cable - I got a quality cable (by quality I mean any branded cable and not the one that comes free with cable box) and everything worked fine.

It's more of a TV not accepting the wrong cable - laptops are pretty flexible.

Regards,

Pawan
