Currently having issues with my lenovo laptop and toshiba tv. My laptop screen cracked some time ago and so i removed this leaving only connecting wires & plastic frame work. I was able to use the laptop by connecting hdmi straight to tv. My boyfriend suddenly unplugged the laptop from the hdmi cable and plugged in his xbox 360.. he could not get this to work. Simce then i am no longer able to connect the laptop to tv. I have purchased a new hdmi cable but thid has made no difference. I have a feeling the output settings have auto changed but as i have no laptop screen i am unable to check the idividual didplay setting. I am able to hear the laptop loading. Any suggestions would be helpful.
