|Dear toxic51 and riider, the problem is not yet solved. |
It is a few hours since toxic51 replied to me and I have simply come back to the site to say thank you to him as any more delay would leave him feeling ignored. At the same time, I have just seen your comments riider.
First things first. Thank you both very much for giving your time and advice. It is genuinely appreciated.
I followed your advice toxic but in the process my laptop screen blacked out whenever I connected the HDMI lead to the laptop output. This time, no picture on the TV either.
I think what I have done is read help and support from Dell and Microsoft, plus the hard copy manuals of both devices for so many hours, I have gone cross-eyed and done something during all my 'tweaking' to alter settings which are causing this.
This is where things stand this minute. I shut down the laptop and turned of the TV. I then disconnected the HDMI lead at both ends. After a break, I re-connected the HDMI first, turned on the TV, selected the correct HDMI source, then booted up the computer.
Result? Black screen on laptop and nothing on TV. Tried to get my screen back up on the laptop but nothing worked. I disconnected the HDMI from the laptop and tried again. Still black screen!
So, I carried out a forced shutdown and after a minute booted up and there was my desktop in pristine condition.
First thing I've done is come here to say thanks. Your advice makes sense but I appear to have created an additional problem. One thing I can tell you both however, is that on Saturday night I did use a very similar procedure and set the TV as the default advice (green tick).
Sorry to have rambled on. I can be brief don't worry. Just please accept my thanks and after further efforts I will post my result here ASAP, tonight or tomorrow if I can.
Cheers guys from across the pond. We love you guys over here.
