Hi, I recently bought a new BenQ monitor with the intention of setting up an extended display, dual monitor setup for my desktop. My first monitor is connected via VGA, and I have connected the second monitor via HDMI. The second monitor was detected and has up to date drivers installed and on display settings I am able to configure the dual monitor set up. However the second monitor remains on standby, so I swapped over the cables (VGA and HDMI) and now the second monitor displays while the first doesn't- only the VGA connection works.
I would be really grateful if anyone could help me out here, thanks!
