SecondGlow vs a new Studio Display

If you have a 27-inch 5K iMac and a newer Mac, the real question isn’t which app to use. It’s whether to buy a new 5K display at all. Apple’s Studio Display is the obvious one. Here’s what $1,599 buys you that your iMac with SecondGlow doesn’t, and the other way round.

Choose a Studio Display if you want a camera and microphones built in, one cable that also charges your laptop, or the iMac off your desk.

Choose SecondGlow if you already have a 5K iMac you like looking at and want it as your Mac’s monitor for $39 instead of $1,599.

Where a Studio Display is better

  • A camera and microphones for calls, built in.
  • One cable that charges your laptop and carries the picture, with more ports on the back.
  • Just a display. No second computer to keep on, new, with Apple’s warranty.

Where your iMac with SecondGlow is better

  • $1,560 less. $39 once, for a screen you already own and already like.
  • Nothing to sell, nothing to throw away. A used 5K iMac sells for a few hundred dollars; as your monitor it’s worth far more to you.
  • It stays a computer. Unplug the cable and the iMac is an iMac again. Nothing is opened or changed.

Which should you choose?

If you’d buy a Studio Display mainly for the screen, try your iMac first: SecondGlow is free for 7 days, so you’ll know on your own desk whether its 5K picture is enough before you spend $1,599. If you need the camera, the microphones or one-cable charging, buy the display.

Other options, including free apps and conversion kits, are in the full guide.
