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...
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?
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!!!
