what is the best portable monitor compatible with a macbook pro (USB 2.0)?

The Duet app will let you use an iPad as a second monitor for your Mac (using a Lightning cable).

There is a kickstarter for a wireless solution called the Luna Display, but like all kickstarters it is still vaporware for the moment:

What is a "portable monitor" and why do you want to use the USB port?. Any recent display/monitor will work with the Thunderbolt/Mini Display Port or HDMI port

Cool. I never saw or used one before. Thanks for the info. I can't comment on which is best though. Maybe try a product review site.

I have the AOC e1659Fwu USB-Powered Monitor and it is freaking awesome! It will only work on a Mac with USB 3.0 so be careful! Sorry, Bob, you won't find any that work on USB 2.0 for Mac.

The GeChic Portable Monitor is another great option. It's a bit more pricey than the AOC but as the saying goes, you get what you pay for...

Hi John, I have seen reviews saying that this monitor doesn't work correctly with MacBook pro but you seem to have a different view. Im looking to buy two of these monitors and connect them both to my mac book pro via USB 3. Do the monitors work perfectly with the mac and are they easy to set up? Also will the mac be able to power them both do you know?

Thank you

What is the best USB monitor today for MacBook Air Mac with OS X 10.10 1.7 GHz Intel Core i7 chip?

How do you run it with 2 USB cables? Is that necessary or possible?

There are some pretty portable monitors compatible with USB 3 notebooks, unfortunately the offer is limited for mac users. One good option is GeChic, which manufactures portable displays with VGA and HDMI interface, wo all you need is a simple adaptor. Another option is the AOC E 1649 FWU 16 in display, which may be connected via USB 2. This could be another abandoned niche by Apple. This is what I need too, and have not decided what to purchase.

I have not tested any, though, but GeChic tech specs recommend it as most appropriate. AOC via USB 2 may be another good option, but am not sure whether the driver works OK with The Captain.

Hello,

AOC E1649FWU USB Powered Monitor is best for macbook pro. I am also using this. It's amazing, has great features and easy to use. Try this. Thanks.

Thanks

I will give a try to http://www.packedpixels.com/collections/all

I have a Lenovo ThinkVision LT1421 - 14" LED Monitor - Portable monitor (USB connection only) and it works perfectly with both my Lenovo T440S laptop from work as well as my wife's MacBook Air with Yosemite.

However, I have just bought a MacBook Pro (with El Capitan) and it does not recognise the monitor. Apple should definitely sort this out, it is a shame that they pride themselves so much about plug & play and this does not work. Complete rubbish.

This is not only an issue for Apple, but for the manufacturer as well. As long as Apple does not have a constant co-operation with other companies, in our case companies, which manufacture USB displays, the results are bad. As an old macuser, I must admit that Apple has not had any major innovation over the last 5 years, bar—perhaps, am not sure—their watch, which does not tell me very much. Curiously enough, Apple has not invested in a genuine pro tablet with a pro OS. iPad Pro has a ‘pro’ just to be there as long as the OS is not fit, and was not planned, for a genuine pro tablet. Portable USB monitors have become more and more used, but this detail seems ignored by Apple. And I stop here. Read above my other considerations on USB displays. There are some, incidentally some of them compatible with OS X too, not that Apple wished that. Why? Do not ask me, I really do not know and am puzzled with this behaviour of Apple. Apple must come up with pretty innovations of other companies, it is a reversed situation against some 5 years ago, and all the other companies strove to come up with Apple.

After waiting for more than a year and hoping that DisplayLink technology will finally be working with OS X I am giving up and selling my AOC e1659Fwuto some Windows user.

There were times when it worked, there were times when it didn't. I don't care whether it's the drivers or OS X updates. It simply is not reliable enough. Even when it worked there is no brightness adjustment so I had to adjust everything according to the brightness of AOC.

I hope that Packed Pixels connected via Thunderbolt will be more reliable, though they are twice as expensive and smaller.

What great features?

Feels cheaply made and I am unable to control brightness.

Poor graphics as well.
