Lenovo is upping the stakes in the all-in-one (AIO) PC wars with a new IdeaCentre that supersizes the screen that's at its heart.

The IdeaCentre B750 will offer users a huge 29-inch display that is also notable for its extra-wide 21:9 aspect ratio (2,560 x 1,080 resolution). To help with multitasking, the company has added its Lenovo Split Screen technology to manage multiple on-screen windows. You can also reach out and touch the display to make use of Windows 8's touchscreen features, or you can use Lenovo Motion Control to handle basic tasks with gestures instead. To make things sound as good as they look, the B750 comes with a built-in 20-watt subwoofer and Dolby Home Theater technology.

You can deck the B750 out with a new Intel Core i7 Haswell processor, 16GB of RAM, a 2TB hard drive, and Nvidia GeForce GTX 760 graphics. Obviously, none of this comes cheap: The starting price for the system is $1,199 when it's available on the Lenovo website starting next month.

For less money, Lenovo has unveiled another three IdeaCentre AIOs, all also to be released in October. The 23-inch B550 starts at $799, while the 21.5-inch B530 should be cheaper still, though pricing is still TBD. Of course, if you add the fastest processors and max out RAM and hard drive space, these can still cost over a grand.

Finally, the A530 is nearly as pricey as the B750, thanks to its ultra-svelte form factor (a mere 0.8 inches thick at its thinnest point), aluminum cladding, and highly tiltable screen (from -5 to 90 degrees). Like the B550, it features a 23-inch display, though its maximum amount of RAM (8GB) and storage (1TB of either hard drive or solid state) are half that of the B series. The A530's starting price is $1,099 and it looks to be a Best Buy exclusive.
