Hi, well in the TV inputs menu, as well as the inputs I'm familiar with, like HDMI (1, 2 and 3) there is a "PC" input option and a "media" option, but tbh I don't really know exactly what they're for or how you connect the laptop to be able to select one of those options (even if it is possible via one of those inputs).
I've tried simply connecting the laptop to the TV via one of the HDMI sockets on the telly and then choosing either the "PC" or "media" option (having already tried the various HDMI input options) but nothing come through. As I mentioned above, I used to connect this laptop to my LG TV, via HDMI, with no problem at all, but can't yet get it to come through on this Bush set for some reason!
I don't actually know what the "monitor switching button" is or where I'd find it on my laptop. Any further help would be much appreciated.
