Laptop to HDTV connection through HDMI

[moxie264]

I have also noticed that my hp laptop is automatically detecting that there are 2 display screens but I continue to get "No Signal" on my HDTV. Could there be problem with the TV itself or possible the laptop? I would appreciate any suggestions and I am reallly stumped by this. I've been working on this for a week, but just essentially trying the same things overs and over...

Hello,
I am trying to connect an HP laptop to a Samsung TV using HDMI cable. Tried using all 3 HDMI ports on TV and 2 different HDMI cables. Have set TV HDMI input to corresponding input as well. Also changed screen resolution on laptop. What else can I do to get this to work? Graphics driver ATI Mobility Radeon HD 4200 series. Error message "No Signal." Please help

Have you tried rebooting the computer with the cable attached?

Have you looked in your screen display options to see if one is blacked out. (Heck, if your computer is newer, there should be a presentation button on one of the function buttons that'll switch between display modes.)

I have tried rebooting the computer with the HDMI cable still plugged in, but I continue to get a "No Signal" error on the tv. I can bring up the display options by selectin Fn/F4. I tried selecting both Duplicate and Extend without any luck. What else can I try?

Does the laptop have a FN + Fkey to swap displays(looks like 2 boxes on the button in most cases.), that is how most work.

Yes, the laptop has the Fn +F4 to bring up the display only. I have to manually select the type of display I want: Computer Only, Duplicate, Extend, Projector Only. The weird thing is that on Halloween night I was able to connect fine. I wish that I knew what I did differently!!!

I would try projector only and see what it does.

Failing that see if windows built in extend desktop works.

I would suggest that you power up the HD Tv after u have connected the HDMI out cable....Then let it be detected by the laptop and then press f4 for a duplicate screen

If I select either Extend or Projector in the display options, the laptop screen goes black and the desktop icons disappear. I have to manually restart the computer.

I still continue"No Signal" on the tv

You are almost at a point that you have to try it on another HDMI TV(or monitor) or try another cable.

Then see if there is something wrong with the HD tv u seem to have forgotten all about that........

I was wondering about that also. I have changed the resolution on the tv to match that on laptop and also have used all 3 HDMI ports to receive a connection.
