HI all, I just purchased a Thunderbolt Display for a reasonable price from the Apple refurbished deals. I was in desperate need of an external monitor to pair up with my MacBook Pro 15" due to limited working screen space. I know the display is out dated and we have 4/5K monitors available to us. But wanted to stick with Apple display for now. My question is seeing as my MacBook Pro is Retina display. Would the overall quality be lower on the display of images etc, would it give a non retina display look. I'm not to clued up on resolution and resizing. I also have not used one before. Did not have time check it out at an Apple Store. Thanks.
