Ensuring that users can upgrade firmware is a major advantage. I once had a firmware problem with an older, nontouch display, and the only fix was to ship it back to the manufacturer. Two of them, in particular, are quite interesting:įirst, a display must be firmware-upgradable by the user. But if the display you’re considering is Windows 8 certified, it does support those features. Other requirements in the certification document involve things that aren’t listed in product specs and that you can’t check for when comparison-shopping. Whether I connect it to a USB 3.0 or USB 2.0 port doesn’t seem to matter: The touch features work fine either way.Īcer Acer’s T232HL is a 23-inch IPS display with touch support. It’s already available at retail, and it comes with a USB 3.0 connection and cable. I’ve been using a 23-inch Acer T232HL panel. Microsoft doesn’t specify a particular version of USB, so USB 2.0 is probably good enough. Bottom line: If you want to attach an external touch display, you’ll need an open USB port on your PC. Because i2C is a circuit-to-circuit connection that’s unavailable when you attach an external monitor, USB is the only practical option as a connection path under those conditions. Microsoft specifies that the touch interface must connect via either USB or the i2C bus. This sheet typically incorporates the capacitive touch sensor as well.ĭell Note the smooth glass extending across the bezel in the Dell S2340T.Īnother key requirement addresses how the touch interface should communicate with system hardware. Various Windows 8 gestures involve swiping inward from the edge of a bezel, which demands a new approach to display design. All of the Windows 8 touch displays I’ve seen add a thin layer of glass that covers both the LCD panel surface and the bezel in a continuous sheet. Microsoft also established fairly strict guidelines governing how displays should integrate side bezels. These sensors are pricey, which clearly contributes to the fairly high price tags on Windows 8-ready desktop displays. The solution of choice for current-generation displays is ten-point capacitive touch sensor arrays, similar to those used in smartphones and tablets. This excludes touch technologies based on side-mounted infrared sensors, for example, as they often can’t detect occluded finger touches. To be Windows 8 certified, a monitor must be able to to react to five simultaneous touch points. Microsoft’s certification requirements for Windows 8 devices are fairly stringent. Fortunately, display quality is great at 1080p on many touch displays. ![]() Even 27-inch touch displays are limited to 1080p and no 2560-by-1440-resolution displays with capacitive touch are yet available for discrete, stand-alone monitors. You won’t find multitouch desktop displays with resolutions higher than 1920 by 1080 (also known as “full HD”). Most boast IPS (in-plane switching) technology, which offers a wide range of satisfactory viewing angles plus good color fidelity. Luckily, current-generation touch displays, though expensive, seem to be using high-quality components. And for the same reason, the current crop of touch-enabled monitors is fairly expensive. Windows 8 certified displays are already hereĪt this writing, Windows 8 isn’t yet a month old, so touch-ready desktop displays constitute a very immature product category. You just need to choose the one that best suits your needs and your budget. The good news is that numerous multitouch displays that fully support Windows 8 are on the horizon. But as you start to use more Windows Store apps, you’ll find yourself reaching out to touch your screen more and more often, and you may start to regret that your display doesn’t support touch. And if you work primarily in traditional desktop applications-such as Microsoft Office, Adobe Photoshop, and various PC games-that’s probably true. Many traditional desktop PC users may feel that touch support is unnecessary for Windows 8. In fact, some new Windows 8 devices come with pressure-sensitive styluses that let you draw or paint digitally with predictable precision.
