I have a MacBook Pro (Retina, Md 2012) running OS X El Capitan 10.11.3.
I purchased 1x DisplayPort to VGA and 1x DisplayPort to DVI.
I plugged these two into the 2x DisplayPorts on the MacBook Retina.
When I view the screens, however, one of them shows up fine but the other is at a low resolution (800x600).
I've seen some related posts, but nothing addressing this situation specifically. Most seem to be dealing with daisy chaining two external displays off of a single DisplayPort, but this MacBook Pro has two ports, so no daisy chaining.
Any thoughts on why the two different resolutions?
