Would like to attached dual monitors to my 5570 and EXTEND. 5570 has one HDMI and one VGA.
Monitors have one VGA and one Display port.
Or even better, is there a device I can always keep both externals plugged into then when I arrive only have to plug ONE cable into the laptop?
We are having the same issue with that same model laptop, no matter what I do, I can't get both external display to work at the same time. I am using an HDMI > DVI converter though. I'm going to try getting an HDMI > DVI cable instead of an adapter and see if that works better. Otherwise, everything I've seen so far says you'll need to dock it.
The docks get *** poor reviews I wanted avoid those. I ended up using two items, making my own dock essentially:
Plugable USB 3.0 Universal Laptop Docking Station for Windows (Dual Video HDMI & DVI / VGA, Gigabit Ethernet, Audio, 6 USB Ports)
and this active adapter:
Plugable Active HDMI to VGA 6ft (1.8m) Converter Cable Supporting up to 1920 x 1080 (60Hz)
