The laptop comes with its own utility for switching among color spaces, which includes Standard (sRGB), PhotoPro (Adobe RGB) and Movie Pro (DCI-P3). The native screen mode really pushes everything (which is common), with a high 3.0 average gamma -- that's good for outdoor viewing, since it pumps up everything in the middle of the tonal range a lot -- but a too-blue white point of 7500K, despite a 6500K target. Peak brightness hits about 510 nits and minimum black about 0.4 (at 100 percent brightness), with contrast across all the profiles roughly 1400:1. Compared to most of its competition, it can look blindingly bright. In direct sun, you'll still find yourself fighting reflections, but the extra brightness does seem to help here.
That high contrast and brightness range is what will likely make the Dolby Vision content you stream while stuck in a hotel room look better than most competitors' once it's enabled. But it won't look as good as your TV, because the display has no local dimming, which is a key component for HDR to perform its magic. However, with the support for the Dolby Vision decoder, you could connect to an external monitor that does have local dimming, such as one of the new LG Nano IPS displays. Then you might be able to get a better view.
Aside from the HDR, Lenovo also says the display has 100 percent Adobe RGB color gamut. While that's true, if you were hoping this screen would be great for photo editing, it's not -- at least if you're picky about colors. For our evaluation unit, it did encompass the entire Adobe RGB gamut, but it wasn't particularly accurate -- Delta E 2000 values almost all between 4 and 6, gamma closer to 2.3 than 2.2 and a color temperature of 7500K.
That's out of the box, so there's room for improvement with third-party calibration software. But Lenovo's utility doesn't support any user calibration. There's a Custom profile, but that's for changing the target parameters -- white point, color space and gamma -- not ensuring that it hits them. DCI-P3 hits its correct gamma of 2.6, but its white point is similarly about 1000K too cool.
At least it charges fast
Performance on my X1 Yoga was excellent, which isn't much of a surprise given its maxed-out configuration: 1.9GHz Intel Core i7-8650U vPro processor, 16GB of 2,133MHz RAM and a 1TB PCIe NVMe SSD. For day-to-day office chores like email and word processing, though, you'll be fine with the entry-level config running a 1.6GHz Intel Core i5-8250U. If your days usually have you handling more intensive tasks -- anything from working in large databases or spreadsheets to creating multimedia presentations -- or you just want more headroom for the future, go ahead and get the i7.
Battery life, though, is a bit disappointing. Lenovo claims up to 15 hours, but that's for a lower-end configuration with a seventh-gen Core i5 processor. The X1 Yoga I tested ran for 7 hours and 34 minutes on our streaming video test. With power and screen brightness adjustments, you can get more work time out of it, but considering the long battery times we're seeing from other systems, this feels short. The thing that saves it, though, is that the USB-C port can charge the laptop to 80 percent in only an hour -- perfect to recharge on those airport layovers -- or you can run the X1 Yoga off an external battery pack.
Premium business 2-in-1 worth flipping for
The Lenovo ThinkPad X1 Yoga ($1,445 at Amazon) is definitely a laptop you won't mind getting from your IT department. Regardless of the configuration, you'll have a flexible, durable two-in-one with advanced features for privacy, security and usability that will help you get your work done.
