Lenovo's ThinkBook Plus series has always been a mixed bag.

The original ThinkBook Plus kicked everything off by incorporating an e-ink display on the back of the laptop's screen. It was an interesting choice, but it didn't really pan out as the plain e-ink tech had limited usage. 

Things mainly stayed the same with the second model. Then, with thethird-gen ThinkBook Plus , Lenovo decided to put the extra screen next to the keyboard. It received mixed reviews with critics pointing out how awkward it was to type the Gen 3 model with the smaller display taking up room.

But with the newest ThinkBook Plus Gen 4 , the rear e-ink display is back (and in color!), there's now a 2.8K resolution panel on the opposite side, and general improvements make this a solid laptop option for shoppers who want something truly unique.

Lenovo ThinkBook Plus Gen 4

The new ThinkBook Plus Gen 4 is one of the finest 2-in-1 laptops for creative professionals, thanks to its OLED and color E-Ink display combo.

As I mentioned before, the latest ThinkBook has returned to a rear e-ink panel. Only this time, it shows color. Of course, because the outer panel is an e-ink screen, colors are not as vibrant as a standard LCD or OLED display. But if you're a creative professional who favors an e-ink display and also wants to understand what colors you're working with, this is the next best thing.

I'll note that the display has a highly noticeable ghosting effect, as many e-ink panels often do. Ghosting, if you don't know, is where objects on a screen leave afterimages when they're moved. Below is a picture of what it looks like.  

Fortunately, this isn't permanent. Switching to the other screen or putting the notebook to sleep fixes this problem. Speaking of which, the other side of the display is a great-looking 13-inch OLED screen. It boasts a 2.8K (2,880 x 1,800 pixel) resolution with a refresh rate of 60Hz. 

OLED monitors typically have a 120Hz refresh rate, but the clarity and vividness of the Lenovo, even at 60hz, is more than good enough. The brightness is set at 600 nits, so it can shine even in sunnier environments. The OLED side has a slew of imaging-enhancing features, too. My favorite two have to be the anti-reflective coating, which ensures visibility when outdoors, and the anti-fingerprint properties to protect against smudges.

Now I can guess what you're thinking. "Is theThinkBook Plus Gen 4  stuck with an OLED on just one side? What if I have color-sensitive work and I don't want to use the e-ink side?" There's a solution for this. When this device was first revealed at CES 2023, it was known as the ThinkBook Plus Twist because its hinge can move a full 360 degrees. This means the OLED screen can be in the back while the E-Ink display now becomes your main view. Both are touchscreens, so you can use the pen on either side without a problem.

You can swivel the ThinkBook Plus display to switch between e-ink and OLED panels.

This is very ingenious. It shows Lenovo thought things through by deciding not to force people to use the e-ink screen at inopportune moments. This is by far my favorite thing about theThinkBook Plus Gen 4 . I like how you have a choice between the two, and I'd recommend using the e-ink display as the main image when working. The technology is much easier on the eyes than the OLED, thanks to the T
