Upgrade to Dell computer monitors. Dell offer a wide variety of computer monitor sizes and specifications intended for a variety of home and office applications. Depending on the model, they're suitable for use with desktop computers, as a second monitor for a laptop, or as a display screen. Select the right display device for your application from Staples comprehensive selection of computer monitors.

Dell computer monitor size and aspect ratio
The size of a computer monitor depends on both its screen size and aspect ratio. The screen size is the diagonal measurement taken from the bottom left of the screen to the top right. Aspect ratio compares the screen's width to its height with a larger ratio indicating a wider screen. Screens with the same diagonal size but different aspect ratios will be very different. The common aspect ratio of 16:9 is the same as that used on most laptops and high definition TVs and offers a reasonably wide view. 

Dell computer monitor pixel density and size
The monitor resolution refers to the number of pixels across and vertically. The greater the number of pixels, the greater the screen definition.  Note that as the screen size increases, so does the size of each pixel, especially when viewed close-up. This is why larger monitors tend to have a higher pixel density to compensate for the loss in definition. Most monitors today have a pixel density of 1920 x 1080 pixels, the same as HDTV, although larger monitors often have what is known as Quad High Definition (2560 x 1440) and Ultra HD (3840 x 2160).

Dell monitor PC connections
Dell offers a number of options for connecting monitors to PCs. Standard definition and HD monitors usually have one VGA port as well as a DVI port that works with most desktops. Other monitors have HDMI, display port, mini display port, or USB sockets to match connectors available on many laptops and newer desktop PCs. The monitor and PC must have at least one connection that's the same. Although Dell monitors come with at least one video cable, in some instances it may be necessary to source a different video cable.

How do you use multiple Dell computer monitors?
Adding a second monitor increases productivity and helps multitasking. PCs can handle two monitors and those with a second video card, four. For desktops, two monitors can emulate a continuous widescreen, providing plenty of space for running multiple applications. Alternatively, using a larger monitor connected to a laptop is easier on the eyes. For desktops, it's a good idea to select monitors with a similar size, aspect ratio, and resolution to avoid scaling issues, although it's possible to adjust resolution using Windows settings.

What's the best Dell computer monitor for gaming?
A gaming monitor should have a high refresh rate to reduce motion blur. Typical refresh rates are 60 Hz, but performance improves at higher refresh rate frequencies. Also, consider the response time as this measures how quickly pixels can change color, for gaming this should be below 8 ms. A HD screen offers a good compromise between speed and definition, especially as graphics cards speeds fall off at higher monitor resolutions.

Which Dell computer monitors are best for photography and video editing?
An IPS screen is ideal as it has a wide viewing angle and colors don't change when viewed from different positions. On older TN screens, the colors vary with the viewing angle. A high-contrast ratio is better because blacks are blacker and whites whiter, while higher definition helps improve picture sharpness.
