Input: (REVISED review, originally 5, now 4 stars)  I've been using the Lenovo on the go almost daily for 3 years, connected to a 15&#34; MacBook Pro. I work with Adobe design programs, so I dump all but a few of the panels onto the Lenovo (see pic), leaving a large, uncluttered design space on the laptop (I configure custom 'workspaces' inside Adobe).  (NOTE: if using a Mac, you need to download the Lenovo driver from displaylink.com.)  For the most part I've been loving it, it's been a godsend. Text and images are crisp. The anti-glare screen is a big plus. I would not use it as a main graphics screen, however. At maximum brightness the screen is noticeably dimmer than the maximum brightness of the MacBook Pro's screen, not a big drawback for my purposes, but it makes for dull colors, and there is a yellowish tint, impossible to correct. There are no color settings. When I bought it I paid a total of $165, not sure I would pay the $300 it's listed for now.  People commented on having trouble with the cover, I don't know why. If you grab one corner and pull up, it's easily removed. The newer ones slide on.  THE REASON FOR DROPPING ONE STAR After 2 years, the monitor suddenly wouldn't power on. I contacted Lenovo directly. GREAT customer service. I was told it actually had a 3-year warranty—almost unheard of, RIGHT? They promptly replaced it (although with a factory refurbished one). BUT THEN, the same thing happened to the 2nd one after less than a year. I contacted Lenovo again, and again they replaced it, to their credit, although this time it was more difficult, since it turned out that the serial number of the refurbished one wasn't in their system. After 2 HOURS on the phone and my having to send them a pic of the serial number, it got straightened out.  Don't know if I'm correct, but I've concluded that THE PROBLEM LIES WITH THE USB CORD'S BEING LOOSE where it connects to the monitor. My guess is it eventually tore wires inside the Lenovo. So, I decided to affix the cord semi-permanently but securely with a glob of silicone (I didn't want to use anything more liquidy that might seep into the connection). It's not pretty (see pic), but I don't care. Hopefully the monitor will now last for years.

Great portable 2nd monitor; BUT beware of loose USB cord connection
