I can't adjust the resolution because Windows doesn't recognise the TV in Screen resolution.
I have tried all sorts of approaches, including deleting all apps and returning to factory settings, but have only mnade limited progress.
I now have this slightly bizarre situation -
If I have both screens connected -
On initial boot the Lenovo logo shows up on the TV, not the monitor
When Windows loads it shows up on the monitor, not the TV
If I go into the BIOS editor it shows up on both screens
If I boot into Windows Safe Mode it shows up on the TV
If I go into Screen resolution when in full Windows only the VGA monitor shows, the TV is not recognised
If I go into Screen resolution when in Safe Mode only the HDMI connected TV shows, the monitor is not recognised
After being in Safe Mode I've tried rebooting into full fat Windows with the VGA connection unplugged, but it still comes up with a black TV screen and I have to plug the VGA back in to see anything
Not sure what to try next....
