Why cant i connect my computer to my sony bravia tv

might be your cable check your cable if not it might be a button on your laptop check the top row of keys

right click on desktop>personalization>display>set up the tv however you want to. Also, make sure the tv input is set to the right hdmi port.

I have HDMI connectet to sony, I also have a cable to the monitor port connected to both, but no signal keeps on apperarin when I tell the tv to use the computer for a signal. I'v attempted all the options in the controle panel for changing displays. It worked two days ago but I have lost the connection capability yesterday. the tv keeps telling me "no signal is it the tv noe seeing the computer or the Toshiba not sending it to the tv? Do you have a opinion what settings I should use for the display options?

Which setup would be the right one. there are several, and i'm not sure which one I used two days ago. I'v connecter the HDMI to most all of the ports on the tv. And the computer only has One each of the HDMI and the monitor ports to plug the HDMI and Monitor ports. I have a Y in the monitor port and the TV to one side of the Y and a samsung 22" to the other side of the Y. Is there an order as to which I plug in first-- TV orr Samsung?

I just tried three sidddernt ports for the HDMI no signal! appears on the tv when I switch between the three HDMI ports. The same wnen I switch to the Monitor podt. I unpluged the samsung from the Y then tried the tv--no signal I think you have to plug in the tv first the reconnect the monitor. Which of the F5 options would get the toshiba to send the signal to the SONY?

Disconnect the computer monitor and try the HDMI to TV only.
