By default most graphics cards won't just start outputting to the HDMI. I have my computer set up with an HDMI connection and the monitor won't show
anything until windows get's to the log-in screen. I have an Nvida graphics card and I had to go into the the Nvidia graphics control system and tell
the computer that I had two monitors and then set the HDMI as the primary monitor. To cover the possibility that you don't have the right HDMI
selected on the TV, most TV's have the HDMI connections labeled on the back of the TV. (HDMI 1, HDMI2 etc.. ) When you switch inputs on the TV you
should be able to select the correct one. If you know you have the correct connection selected on the TV but are still getting "no input signal"
then either the TV can't understand the information the computer is putting out or the graphics card isn't outputting anything to the TV. I would
advise that you have your normal monitor connected as well as long as that monitor isn't connected to the HDMI port. This might allow you to see
other messages that you might not be seeing when you connect to the TV with HDMI.
Hey! Same problem here with two different tv's. Put your hdmi cable in hdmi2, worked on both, laptop straight to TV, yes the first hdmi1 didn't
work for me either, so try that, hope you get sorted. You may have to also go to menu, input, then scroll down to Hdmi2, but you should have no other
problems than posted above, good luck! Let me know
to make it simple try this. Turn computer off. Disconnect the original computer monitor you have connected to the pc.. Hook up HDMI cable from
computer video card to HDMI port on tv. Turn on TV. Now turn on computer. Does it work? Some video cards need to detect both the TV and computer
monitor at time the computer is turned on.
