The touchscreen is a barely oddball dimension at 14.5 inches diagonally, providing a 16:10 facet ratio at a decision of three,072 x 1,090 pixels. The show is backlit by the newish mini LED know-how (similar as on the 12.9-inch iPad Pro), which makes use of hundreds of tiny LED mild sources to create individually controllable dimming zones. The affect is highly effective: Not solely are pictures extremely lifelike, with spectacular distinction, the machine is so brilliant it’s painful to take a look at at full energy. I’ve been commonly cataloging laptops with “file” brightness ranges all 12 months, one after another, however the Lenovo Slim put all of them to disgrace, beating the next-highest brightness benchmark I’ve measured by 38 p.c. I’m assured that this new file goes to face for a while.
The Slim Professional 9i places up the efficiency numbers to again that up, too. With an overclockable CPU and devoted graphics, there’s loads of juice to drive stable benchmarks on each enterprise and graphics assessments. Unsurprisingly, the laptop computer didn’t fare in addition to HP’s Envy 16, which has a extra highly effective Core i9 CPU and a higher-end graphics card, however much less RAM. On common, the Slim Professional 9i was 20 to 30 p.c slower than the Envy 16 throughout the board—however I’ll rapidly be aware that it nonetheless gives spectacular, wholly workable efficiency. If it has a efficiency flaw, it’s that storage operations—putting in apps and getting them to load—are an obvious bottleneck.
The Slim Professional 9i isn’t all about what’s underneath the hood. The keyboard, with its 1.5-mm journey (known as out particularly on a sticker on the chassis), is certainly among the best I’ve encountered in years, and the touchpad is roomy and fairly quiet when clicked. 4 Dolby Atmos audio system present loads of audio energy, with a thumping bass that noticeably causes the chassis to vibrate once you get away the bangers. Enlargement is ample, with two USB-A ports, HDMI, an SD card reader, and two USB-C ports, one in every of which helps Thunderbolt 4.
