Hdmi connection not working toshiba laptop
Hello, I have been trying for hours and hours - sometimes getting different results - using hdmi to hdmi - toshiba laptop to sony TV - can't get it to recognize tv as a device then once in a blue moon it does pop up as a device - no matter what can't get anything to it....downloaded new driver just in case - that did not work. Toshiba is a satellite p305. Now sometimes when connected I can only see a blue screen with windows logo on my monitor and nothing else. uuuugh...no consistency and no answers....called toshiba - nothing...
checked no bent pins - downloaded the latest toshiba driver and downloaded something called a hdmi controller that does nothing....tv is set to the proper video 7 selection which the manual says is the hdmi connection in the back - I downloaded a copy of the manual but it has been pretty useless....uuugh....
this link had some stuff that seemed useful but it lost me.....BUT it seemed to resolve for someone - I am having trouble following it...
this is all my manual says and no other page reference:
HDMI-CEC (Consumer Electronics Control) is a standard in the
CE Industry which allows devices to work together over an HDMI
cable. Toshiba notebooks with HDMI-CEC include a Toshiba
utility dedicated to take advantage of its capabilities which can
allow you to:
❖ Use the TV remote control to output the computer screen onto
the TV screen.
❖ Use the TV remote control to launch, operate and close
applications on your computer.
❖ Turn on the TV when the HDMI output is selected using the
❖ Switch the video output (HDMI or LCD) when executing
certain desktop icons.
❖ Enable/Disable the HDMI-CEC function on the computer.

and this which just says cycle the function 5 key - BUT with the cable in and tv off I have no screen at all to see anything....that is the strange thing
The quickest way to change the display output settings is to use the
display hot key (Fn + F5):
1 While holding down Fn, press F5 repeatedly until the setting
you want takes effect. Briefly pause each time you press the F5
key to allow time for the display to change.
This hot key cycles through the settings in the following order:
❖ Built-in display only
❖ Built-in display and external monitor simultaneously
❖ External monitor only
❖ Built-in display and TV (or other external video device)
❖ TV (or other external video device) only
❖ Built-in display and external monitor (extended desktop)
❖ Built-in display and TV (extended desktop)
❖ Swap—Switch primary display between internal display
and external monitor when using extended desktop
