Ok so after trying EVERYTHING I can think of to get this resolved.... I'm slowly losing my mind.
Basic history. For a couple of years now I've been using my Sony Bravia HD as my display monitor for my PC. Since using it I've hardly ever had a problem with it save for one. This one problem is something I've experienced only a couple of times in those years and I have it again now with ALL the same symptoms except this time I haven't been able to solve it!
I came home one day (with my PC left running) and there was nothing on the display which I thought was weird because I'd done nothing before I left except left it to download.
I've now.... after spending hours tinkering, been able to get my display back by hooking it back up to my monitor but I WANT it back to my HD Sony Bravia.
Well, I've updated the graphics card (which really shouldnt have been neccessary as the driver
was fairly up to date and worked fine before anyway).
I've tried going into display settings but there's nothing to directly TELL windows to look for a different display device.
I've tried different HD slots and nothing, different cables and the cables work fine.
The interesting thing is this. one of the symptoms I had before when I had this problem was that when I plugged in a lead from the PC to the default dell monitor AND also plugged in a HD lead for hd to hd from pc to tv, what I get is a blank desktop on the dell monitor. everything suddenly dissapears (no icons, taskbar NOTHING, just the background) and nothing on my TV.
This has happened before but I've got it working, Not sure how but I think a reboot with just the HD lead in did it, doesn't work now.
Then when I unplug the hd lead from the graphics card and leave the monitor lead to the dell monitor IN, the desktop comes back.
What I've done before is shutdown or restart with just the HD lead to TV in but this isn't working now. I've changed NOTHING settings wise on my TV since it was working and the same with my PC other than uninstalling and reinstalling some C++ and .net framework 4 which has no relation to this problem.
Can somebody PLEASE tell me if there is something I'm missing because I've had this problem before but it's always come back. I really don't want to revert back to this monitor.
