Can't Connect Laptop to TV with HDMI

Jump to solution

I've been trying to connect my Dell Studio to my Philips HDTV with a HDMI-HDMI cable, however my laptop does not recognize that an external monitor is attached.

I've tried using several different HDMI cables so I don't believe that's the problem.  I have my television set to the correct source.  I've tried hitting the F1 button on my keyboard to select a dual monitor display setting, however changing it doesn't matter because the television is not recognized.  I have connected my laptop to another TV using HDMI-HDMI in the past.  I am able to connect to this television using a VGA cable.

I'm not sure what other steps I could try taking.  Is there a setting on my computer or on my television that I need to change in order for my laptop to recognize the external monitor?

 

Thanks for any help.

You should mention your operating system and exact computer model. Open Display in Control Panel (or your video software if you have that) and see if you can select external display or switch to HDMI. When you say you have the correct input selected, make sure it is one of the HDMI inputs, not the PC input which is only for the vga port. Read the info in Windows Help about Connecting a TV to see what you might have missed.You should also check the Philips tv manual.

OS: Windows 7

Computer Model: Dell Studio 1558

Ok, when I open Display in the Control Panel all I see is:

- Adjust resolution

- Adjust brightness

- Calibrate color

- Change display settings

- Connect to a projector

- Adjust ClearType text

- Set custom text size (DPI)

"Change display settings" brings me to the Screen Resolution screen that doesn't recognize the external monitor.

"Connect to a projector" shows the pop up for "computer only," "duplicate," "extend," and "projector only."  These don't do anything though since the television isn't recognized.  I do have the HDMI source selected and not PC.

Windows Help told me to shut down my computer, attach the HDMI to the TV, turn on the TV, and then turn on my computer.  However, that still did not get me an image.

I've tried contacting Philips and they can't find any problems with how I'm connecting to the television.  Anyone have any other ideas for what I could be overlooking on my laptop?

Do you have another HDMI devide to connect to the TV to verify that:

A) The correct HDMI port is selected on your TV

B) that the particular HDMI port on your TV is not defective

Yeah there are 2 HDMI ports on my TV.  I've tried both.  And someone else used this TV as a dual monitor before I got a hold of it, so unless the port went bad very recently then I don't think that's the problem.

I found that a 15ft "Rosewill" brand HDMI cable does not work with my Dell Inspiron and Sony Bravia LCD TV(no recognition of either).Yet,a 5 ft. "Rosewill" brand HDMI cable works fine.If it is working,you can right click the desktop and it will give you options of connecting to "DIGITAL TV".(with a little searching).Hope this is of help to someone out there.

For what it's worth:

My problem had to do with my laptop's fan malfunctioning, causing overheating.  This eventually made my laptop's backlight turn off, which forced me to look into the problem.  Once the fan was fixed, the HDMI worked with no problems.

Solution is here http://forums.cnet.com/7723-13974_102-543610/unable-to-mirror-dell-xps-15z-s-display-on-a-hd-tv/

Basically you need to configure the display through the Nvidia control panel (right click on your desktop)

 

This worked for me Smiley Happy
