The Good With one of the only 21:9 screens we've seen on a PC, the Lenovo IdeaCentre B750 offers a ton of desktop space to fill with browser windows and productivity apps. With the right software, Blu-ray and HD movies can play without letterbox bars, and games feel much more immersive.
The Bad The midlevel graphics card, left over from last year, can't push the higher screen resolution and high-end game settings at the same time; bundled media player software oddly doesn't help with 21:9 playback, and the lack of a touch screen feels dated.
The Bottom Line A refreshing new way to look at all-in-one desktops, the Lenovo B750's Blu-ray-friendly, extra-wide display is great for movies (if you add some extra software), and games greatly benefit from a wider field of view. It's different, and fun to use, but it cries out for a touch screen.
Lenovo's B750 all-in-one desktop PC isn't the first system we've seen with a wider-than-normal screen, but it's still a relatively rare animal. And, with a discrete GPU, high-end CPU, and excellent IPS display, it's also a fun alternative to run-of-the-mill all-in-ones, and hopefully something we'll see more of in the future.
The B750 swaps the usual 1,920x1,080 screen, a 16:9 aspect ratio (the same as HDTV screens), for a 2,560x1,080 screen, which works out to 21:9, or the same as many theatrical release films. Technically, the aspect ratio is 64:27, but that's commonly rounded to 21:9. This wider style of display may never become a mainstream trend, but it's a nice change of pace and serves three major goals.
Third, the wide desktop allows you to put full apps and browser windows side by side, much as one might do on a multiple monitor setup. For example, putting a Web browser and Word doc next to one another, or a large video playback window and another app.
At $1,449 for our configuration, which included a current-gen Intel Core i7 CPU, a big 2TB HDD, 8GB of RAM, and a Nvidia GeForce GTX 760 graphics card, the B750 feels fairly priced, considering its unique features. My most notable complaints are two-fold: the older video card (Nvidia is up to the 800-series now) suffers from serious frame-rate drops when trying to push the higher native resolution; and the otherwise excellent display isn't a touch screen, making Windows 8 hard to use, and making the entire system feel dated.

Design and features
The Lenovo B750 cuts a different desktop footprint than other all-in-one PCs, just because it takes up so much room. The screen itself measures 29 inches diagonally, but it's an entirely different aspect ratio, so that translates to a shape that's wider and shorter than a regular 16:9 monitor of the same size would be. You won't mistake this for a high-design all-in-one like the Apple iMac or even Dell's excellent XPS 27, and at 32.5 pounds it's heavy enough that you'll want to move it only when absolutely necessary.
Bundled with the system are a basic Lenovo wireless keyboard and mouse. The keyboard is slim and angles up at the rear. It includes a full number pad, but I like my space bars a little wider, and the backspace button is too small. The plastic mouse is as basic as it gets; if you want to use the B750 for gaming, I'd suggest a more specialized model with more buttons and a sleeker shape.
The end effect is still very impressive, giving you an expanded sense of peripheral vision in games, which is even more immersive in some ways than playing in stereoscopic 3D, which can have a tunnel-vision effect. Skyrim, the expansive fantasy RPG, worked well, although I had to force the correct resolution in a config file. Metro: Last Light and BioShock Infinite both also benefited from the added field of vision, although their detail levels needed to be knocked back for smooth gameplay.
Seeing this wider screen up close while gaming, I quickly got used to it, making it a letdown to go back to a normal 16:9 display. To take it one step further, I can see how having a curved 21:9 display would be even more immersive, although I'm not aware of any curved 21:9 PC monitors for sale right now.
Audio from the 2.1 speakers was good for internal sound, helped by a rear-firing subwoofer on the back of the chassis, but you'll still want to hook up external speakers if you're DJing a party from your desktop.

Connections, performance, and battery
One of the nice things about working with a full all-in-one desktop computer rather than a laptop, tablet, or even hybrid "tabletop" all-in-one is having plenty of room for ports and connections. Here, you get a total of six USB ports, although one is needed for the included keyboard/mouse dongle, as well as both HDMI-in and HDMI-out connections. The former is interesting in case you want to hook up an external source -- a tablet, laptop, game console, or other device -- and just use the B750's display.
The Nvidia GeForce GTX 760 graphics card in the system is good for mainstream gaming but a few stops short of the top of the line (and part of last year's 700-series of cards from Nvidia). We tested games two ways -- at the same 1,920x1,080 resolution we use to test other PCs, and also at the higher 2,560x1,080 resolution. At 1,920x1,080, the B750 ran BioShock Infinite at high detail settings at 23.5 frames per second; bumping up to 2,560x1,080 gave us 17.9 frames per second. In Metro: Last Light at both resolutions, a challenging benchmark, the scores were 10.0 frames per second and 7.7 frames per second, respectively.
While gaming is a major attraction of this unusual screen size/resolution, it's disappointing that you can't crank game detail levels up. I'd be willing to pay a bit more for a newer, higher-end GPU.
Conclusion
The Lenovo B750 is unusual, and it's not for everyone. But if you're looking to skip the multiple monitor setup while still maximizing screen real estate, it's an interesting way to go. And "interesting" is the operative word here. Games, while requiring a detail/frame rate trade-off, take on a new immersive quality on a 21:9 screen, and movie-watching feels more cinematic.
Even better, with a high-end CPU, a big 2TB hard drive, a decent GPU, and a massive extra-wide display all for $1,449, it's a decent deal if you're looking for a desktop that's a little different without breaking the bank. But beyond the specs and price, I just found it fun to use. With a few tweaks, such as a touch screen and a faster GPU, it could be a hard-to-beat alternative to more common all-in-ones.
