So, second hand PCs, Dells. Want to run them with 2 monitors. Windows 7 does this.
So, buy VGA splitter cable. Install. I get duplicate monitors. But that’s all.
!windows button! P gives monitor choices. I want extend, not duplicate. But it won’t take. Won’t work, nowt happens.
So, am I being an idiot here? What is it that I’ve not done?
